Introduction
1.1 Overall Operation
The SIPROTEC® 4 7SJ62/63/64 are numerical, multi-functional, protective and con-trol devices equipped with a powerful microprocessor. All tasks, such as the acquisi-tion of the measured quantities, issuing of commands to circuit breakers and other pri-mary power system equipment, are processed in a completely digital way. Figure 1-1illustrates the basic structure of the devices 7SJ62/63, Figure 1-1 illustrates the basicstructure of the device 7SJ64.
Analog Inputs The measuring inputs (MI) section consists of current and voltage transformers. Theyconvert the signals from the measuring transducers to levels appropriate for the inter-nal processing of the device.
Four current inputs are available in the MI section. Three inputs are used for measur-ing of the phase currents. The use of the fourth input depends on the version of thedevice ordered. The fourth input can be used for measuring the ground current as theresidual of the phase current transformers (In), or for measuring the ground currentfrom a separate current transformer (INs/3I0). The latter is used in a highly sensitive

The 7SJ62/63 has three voltage inputs in the MI section. The inputs can either be usedto measure the three phase-ground voltages, or two phase-phase voltages and 3V0from, for example, open delta voltage transformers. Displacement voltage is anotherterm used for 3V0. It is also possible to connect two phase-to-phase voltages in open-delta connection.
The 4 voltage transformers of 7SJ64 can either be applied for the input of 3 phase-ground voltages, one displacement voltage Uen or a further voltage for the synchroniz-ing function.
The analog input quantities from the MI stage are passed on to the input amplification(IA) stage, which provides high-resistance terminations for the analog quantities. TheIA stage consists of filters for processing the measured values. The filters are opti-mized with regard to bandwidth and processing speed.

Introduction
The analog-to-digital (AD) stage consists of memory components, a multiplexer, andan analog-to-digital (A/D) converter. The A/D converter processes the analog signalsfrom the IA stage. The digital signals from the converter are input to the microcomputersystem where they are processed as numerical values in the residing algorithms.
MicrocomputerSystem
The actual protection and control functions of the 7SJ62/63/64 are processed in themicrocomputer system (µC). In addition, the µC controls the measured quantities.Specifically, the µC performs:
− Filtering and preparation of the measured quantities
− Continuous monitoring of the measured quantities
− Monitoring of the pickup conditions for the individual elements and functions
− Evaluation of limit values and sequences in time
− Control of signals for the logic functions
− Decision for trip, close, and other control commands
− Output of control commands for switching devices (output contacts)
− Recording of messages and data for events, alarms, faults, and control actions, andprovision of their data for analysis
− Management of the operating system and the associated functions such as data re-cording, real-time clock, communications, interfaces, etc.
Binary Inputs andOutputs
The µC obtains external information through the binary inputs such as blocking com-mands for protective elements or position indications of circuit breakers. The µC is-sues commands to external equipment via the output contacts. These output com-mands are generally used to operate circuit breakers or other switching devices. Theycan also be connected to other protective devices, annunciators, or external carrierequipment for use in Pilot-Relaying schemes.
Front Elements The devices with integrated or detached operator panel light-emitting diodes (LEDs)and a display screen (LCD) on the front panel providing information such as messagesrelated to events and functional status of the device.
Integrated control and numeric keys in conjunction with the LCD facilitate local inter-action with the 7SJ62/63/64. All information of the device can be accessed using theintegrated control and numeric keys. The information includes protective and controlsettings, operating and fault messages, and metering values (see also Chapter 2).The settings can be modified; the procedures are discussed in Chapter 2. In addition,control of circuit breakers and other equipment is possible from the 7SJ62/63/64 frontpanel.
Serial Interfaces A serial PC Port on device is provided for local communications with the 7SJ62/63/64 through a personal computer. Convenient operation of all functions of the device ispossible. The operating program DIGSI® 4 is required which facilitates a comfortablehandling of all device functions.
A separate Service Port can be provided for remote communications via a modem,or substation computer. The operating program DIGSI® 4 is required. This port is es-pecially well suited for the fixed wiring of the devices to the PC or operation via a mo-
4 7SJ62/63/64 ManualC53000–G1140–C147–1
Overall Operation
dem. The service port can also be used to connect a RTD-Box (= resistance temper-ature detector) for entering external temperatures (e.g. for overload protection).
The additional port (only 7SJ64) is exclusively designed for the connection of a RTD-Box (= resistance temperature detector) for entering external temperatures.
All 7SJ62/63/64 data can be transferred to a central control and monitor system (RTU/SCADA) through the Scada Port. Various protocols and physical interfaces are avail-able to suit the particular application.
A further port is provided for the time synchronization of the internal clock via externalsynchronization sources.
Further communications protocols can be realized via additional interface modules.
Power Supply The 7SJ62/63/64 can be supplied with any of the common power supply voltages from24 VDC to 250 VDC. The device can also be supplied with 115 VAC. Momentary dipsof the supply voltage up to 50 ms are bridged by a capacitor (see Technical Data, Sub-section 4.1). Voltage dips can occur, for example, if the voltage supply system (sub-station battery) becomes short-circuited or experiences a severe variation in load.

Introduction
1.2 Applications
The numerical, multi-functional SIPROTEC® 4 7SJ62/63/64 are versatile devices de-signed for many applications. The 7SJ62/63/64 can be used as protective, control,and monitoring devices for distribution feeders and transmission lines of any voltagein networks that are grounded, low-resistance grounded, ungrounded, or of a compen-sated neutral point structure. The devices are suited for networks that are radial orlooped, and for lines with single or multi-terminal feeds. The 7SJ62/63/64 areequipped with motor protection applicable for asynchronous machines of all sizes.
The 7SJ62/63/64 includes the functions that are necessary for protection, monitoringof circuit breaker positions, and control of the circuit breakers in straight bus applica-tions or breaker-and-a-half configurations; therefore, the devices can be universallyemployed. The 7SJ62/63/64 provides excellent backup facilities of differential protec-tive schemes of lines, transformers, generators, motors, and busbars of all voltage lev-els.
ProtectiveFunctions
Non-directional overcurrent protection (50, 50N, 51, 51N) is the basis of the 7SJ62/63/64. Four definite-time overcurrent protective elements exist, two for the phase and twofor the ground (50 and 50N) currents. The elements can be set with no time delay,where instantaneous tripping is desired. Inverse-time overcurrent protective elementsare also available for both the phase and the ground (51 and 51N) currents. The com-mon U.S. ANSI time-characteristics are also available. Alternatively, user-definedcharacteristics can be programmed or IEC characteristics can be selected.
Depending on the version of the device that is ordered, the non-directional overcurrentprotection can be supplemented with directional overcurrent protection (67, 67N),breaker failure protection (50BF), and sensitive ground fault detection for high-resis-tance ground faults or systems that are resistively grounded (50 Ns, 67Ns). The highlysensitive ground fault detection can be directional or non-directional.
Other protective functions are available, some of which depend on the version of thedevice that is ordered. These additional functions include negative sequence (phasebalance) current protection (46), automatic reclosing (79), thermal overload protection(49), overvoltage protection (59), undervoltage protection (27), and over/under fre-quency protection (81O/U). For motor protection, starting time supervision (48), startinhibit (66/68), and undercurrent monitoring (37) are optionally available. Finally, the7SJ62/63/64 is equipped with a fault locator.
A protection feature can be ordered for the detection of intermittent ground faultswhich detects and accumulates transient ground faults.
External detectors account for ambient temperatures or coolant temperatures (bymeans of an external RTD-box).
Before reclosing after three-pole tripping 7SJ64 can verify the validity of the reclosureby voltage check and/or synchronous check. The synchronization function can also becontrolled externally.
Control Functions The 7SJ62/63/64 supports all control and monitoring functions that are required for op-erating medium to high-voltage substations. A major application is the reliable controlof switchgear or circuit breakers. Such control can be accomplished via the integratedoperator panel, the system interface, the binary inputs, and the serial port using a per-sonal computer with DIGSI® 4.
6 7SJ62/63/64 ManualC53000–G1140–C147–1
Applications
The status of the primary equipment or auxiliary devices can be transmitted to the7SJ62/63/64 via auxiliary contacts connected to binary inputs. The present status (orposition) of the primary equipment can be displayed on the 7SJ62/63/64, and used forinterlocking or, if applicable, plausibility monitoring. Only the quantity of binary inputsand outputs available in the 7SJ62/63/64 limits the number of primary devices that canbe operated. Depending on the primary equipment being controlled, one binary input(single indication) or two binary inputs (double indication) can be used in the positionmonitoring process.
The capability of switching primary equipment can be restricted by a setting associat-ed with switching authority – Local, DIGSI® 4 PC, or Remote, and by the operatingmode – Interlocked or Non-Interlocked, with password request. Processing of inter-locking conditions for switching (e.g. switching error protection) can be establishedwith the aid of integrated, user-configurable logic functions.
Messages andMeasured Values;Recording of Eventand Fault Data
The operating messages provide information about conditions in the power systemand the 7SJ62/63/64. Measurement quantities and values that are calculated can bedisplayed locally and communicated via the serial interfaces.
Messages of the 7SJ62/63/64 can be indicated by a number of programmable LEDson the front panel, externally processed through programmable output contacts, andcommunicated via the serial interfaces (see Communication below).
Important events and changes in conditions are saved under Annunciation in theEvent Log or the Trip Log, the latter being used for faults. Waveform capture is avail-able, as an option.
Communication Serial interfaces are available for communications with PC’s, RTU’s, and SCADA sys-tems.
A 9-pin D-subminiature female connector on the front panel is used for local commu-nications with a personal computer. DIGSI® 4 software is required to communicate viathis port. Using the DIGSI® 4 software, settings and configuration can be made to therelay, Realtime operating quantities can be viewed, Waveform capture and Event Logrecords can be displayed, and controls can be issued.
A DIGSI® 4 service interface port, a system (SCADA) port and a time-sync port (IRIG-B or DCF77) are optionally available on the rear of the device.
A rear service interface can be supplied as RS-232, RS-485, or multimode fiber opticstype ST. DIGSI® 4 software is required to communicate via this port.
The additional port (only 7SJ64) is designed exclusively for connection of a RTD-Box(= resistance temperature detector) for entering external temperatures. It can also beoperated via data lines or fibre optic cables.
A rear system interface can be supplied as RS-232, RS-485, or multimode fiber opticstype ST for communications between the 7SJ62/63/64 and a PC’s, RTU’s, or SCADAsystems Standard Protocols, IEC 60870–5–103 are available via the system port. In-tegration of the devices into the automation systems SINAUT® LSA and SICAM® alsotake place with this profile.
Alternatively, a field bus coupling with PROFIBUS FMS is available for the 7SJ62/63/64. The PROFIBUS FMS is performed in accordance with IEC 61850, is an open com-munications standard that particularly has wide acceptance in process control and au-tomation engineering, with especially high performance. A profile has been defined forthe PROFIBUS communication that covers all of the information types required for

Introduction
protective and process control engineering. The integration of the devices into the en-ergy automation system SICAM® can also take place with this profile.
Besides the field-bus connection with PROFIBUS FMS, further couplings are possiblewith PROFIBUS DP and the protocols DNP3.0 and MODBUS. These protocols do notsupport all possibilities which are offered by PROFIBUS FMS.

2.1 General
The settings associated with the various device functions may be modified using thecontrols on the front panel of the device or by using the operator interface in DIGSI® 4in conjunction with a personal computer. The SIPROTEC® 4–System Manual gives adetailed description of the procedure. Therefore, it will only be described briefly here.Password No. 5 is required to modify individual settings.
From PC withDIGSI® 4
To select a function, the user should double-click on Settings, and then double-clickon the desired setting function (e.g. Power System Data 1 is selected by double-clicking Settings, and then double-clicking Power System Data 1 as illustratedin Figure 2-1).
Figure 2-1 Navigating Using DIGSI® 4 — Example
A dialog box associated with the selected function is displayed (e.g., if Power Sys-tem Data 1 function is selected, the dialog box shown in Figure 2-2 will appear). Ifa function contains many settings, the dialog box may include multiple windows. In thissituation, the user can select individual windows via tabs located at the top of the dia-log box (e.g., In Figure 2-2, tabs exist for Power System, CTs, VTs, and Break-er).

Figure 2-2 Power System Data Dialog Box in DIGSI® 4 — Example
The left column of the dialog box (identified as the No. column) contains the four-digitaddress number of the setting. The middle column of the dialog box (identified as theSettings column) contains the title of the setting, and the right column of the dialogbox (identified as the Value column) contains the current value of the setting in textor numerical format. When the mouse cursor is positioned over a numerical field in theValue column, the allowable range is shown.
To modify a setting, the user must click on the setting value which is displayed in theValue column.
Text Values When a text setting value is selected, a pull-down menu of possible setting options isdisplayed. To modify the setting, the user simply clicks on the desired option. The pull-down menu closes, and the new setting value appears in the Value column.
Numerical Values(including ∞)
When a numerical setting value is selected, the setting is modified using the numberkeys, if applicable, with a decimal comma (not a decimal point). A value of “infinity”may be entered by pressing the small o key twice. The setting modification is con-firmed by clicking on Apply, or the user may select another setting to modify.
If the value entered is outside the allowable range, a message block appears on thescreen describing the error and displaying the acceptable range of values. To ac-knowledge the message, the user should click OK, and the original value reappears.A new entry can be made or another setting value can be modified.
Primary orSecondary Values
Setting values can be entered and displayed in primary terms or secondary terms, asdesired. DIGSI® 4 automatically performs the conversions. For this, the station datahave to be entered correctly.

2.1.1 Configuration of Functions
General The 7SJ62/63/64 relay contains selectable protection functions as well as many otherfunctions, based on the options purchased. The first step in configuring the relay is todetermine which functions are required.
Example for the configuration of functional scope:
A protected system consists of overhead and underground feeders. Since automaticreclosing is only needed for the overhead feeders, the automatic reclosing function isnot configured or “Disabled” for the relays protecting the underground feeders.
The available functions must be configured as enabled or disabled. For individualfunctions, the choice between several alternatives may be presented, as describedbelow.
Functions configured as disabled are not processed by the 7SJ62/63/64. There areno messages, and corresponding settings (functions, limit values) are not displayedduring detailed settings.
197SJ62/63/64 ManualC53000-G1140-C147-1
Functions
Determination ofFunctional Scope
Configuration settings must be entered using a PC and the software programDIGSI® 4 and transferred via the front serial port, or via the DIGSI® 4 serial port inter-face. Operation via DIGSI® 4 is described in the SIPROTEC® 4 System Manual.
Entry of password No. 7 (for setting modification) is required to modify configurationsettings (see Section 4). Without the password, the settings may be read, but may notbe modified and transmitted to the device.
The functional scope with the available alternatives is set in the Device Configu-ration dialog box to match equipment requirements.
SpecialCharacteristics
Most settings are self-explaining. Peculiarities will be explained in the following.
If use of the setting group change function is desired, address 0103 Grp Chge OP-TION should be set to Enabled. In this case, up to four different groups of settings(see Chapter 6) may be entered quickly and easily during device operation. Only onesetting group may be selected and used if the setting is Disabled.
For the relay elements associated with non-directional overcurrent protection (bothphase and ground), various tripping characteristics may be selected at the addresses0112 Charac. Phase and 0113 Charac. Ground. If only the definite time char-acteristic is desired, then Definite Time should be selected. Additionally, depend-ing on the relay model ordered, various inverse time characteristics are available(based on either IEC (TOC IEC) standards or ANSI (TOC ANSI) standards), or userdefined characteristics may be specified. The dropout behavior of the IEC and ANSIcurves will be specified later during the setting (addresses 1210 and 1310), however,for the user-defined characteristic you determine in address 0112 and 0113 whetherto specify only the pick-up characteristic (User Defined PU) or the pick-up and thedropout characteristic (User def. Reset).
The superimposed high-current stage 50-2 is available in all these cases. Non-direc-tional overcurrent protection may be defeated during configuration by selecting Dis-abled.
For directional overcurrent protection, the same information can be entered at ad-dresses 0115 67/67-TOC (phase) and 0116 67N/67N-TOC (ground) that was en-tered for the non-directional overcurrent protection at addresses 0112 and 0113.
For sensitive ground fault protection, address 0131 Sens. Gnd Fault is used tospecify whether the function should be Disabled, enabled with definite time trippingcharacteristics only (Definite Time), or enabled with a user defined inverse timecharacteristic (User Defined PU).
For the intermittent ground-fault protection specify in address 0133 INTERM.EF themeasured quantity (with Ignd, with 3I0 or with Ignd,sens.) which is to beused by this protection function.
For negative sequence protection, address 0140 46 is used to specify whether thefunction should be Disabled, enabled with Definite Time tripping characteristicsonly, or enabled with an inverse time characteristic (TOC IEC or TOC ANSI).
Note:
Available functions and default settings are depending on the ordering code of the re-lay (see table 2-1 and ordering code in the appendix for details).
20 7SJ62/63/64 ManualC53000-G1140-C147-1
General
Set in address 0142 49 for the overload protection whether (With amb. temp.) ornot (No ambient temp) the thermal replica of the overload protection will accountfor a coolant temperature or ambient temperature or whether the entire function is setto Disabled.
Up to four function groups are available for the synchronizing function. They are en-abled in address 016x (x = 1 ... 4). Parameters 0161 25 Function 1 to 0164 25 Function 4 indicate whether a synchronizing function is to be Disabled or en-abled. The latter is determined by pre-selecting the operating mode ASYN/SYNCHRON(switching takes place for asynchronous and synchronous conditions) or SYNCHRO-CHECK (corresponds to the classical synchro-check function). The function groupswhich are configured to enabled via ASYN/SYNCHRON or SYNCHROCHECK are dis-played when you select the synchronizing function; function groups set to Disabledare hidden.
For trip circuit monitoring, address 00182 74 Trip Ct Supv is used to specifywhether two binary inputs should be utilized (2 Binary Inputs), one binary inputshould be utilized (1 Binary Input), or the function should be Disabled.
If you want to detect an ambient temperature or a coolant temperature and send theinformation to the overload protection, specify in address 0190 RTD-BOX INPUT theport to which the RTD-box is connected. For 7SJ62/63 Port C (service port) is usedfor this purpose, for 7SJ64 either Port C (service port) or Port D (additional port).The number and transmission type of the temperature detectors (RTD = ResistanceTemperature Detector) can be specified in address 0191 RTD CONNECTION: 6 RTD simplex or 6 RTD HDX (with one RTD-box) or 12 RTD HDX (with two RTD-boxes).Appendix A.3.4 gives design examples. The settings in address 0191 has to complywith those at the RTD-box (see Subsection 2.17.2).

2.1.2 General Device Data
The device requires some general information such as the type of annunciation to beissued in the event a power system fault occurs.
The required data can be entered directly at the device if it features an integrated ordetached operator panel: Select the MAIN MENU by pressing the key. Using the
key, select Settings, and then press the key to navigate to the SETTINGSdisplay. There use the key to select the Device submenu.
Double-click SETTINGS in DIGSI® 4 and the corresponding menu appears. A dialogbox will open under the option Device in which you can configure the individual pa-rameters.
“No Trip – No Flag”Option
The indication of messages masked to local LEDs, and the maintenance of spontane-ous messages, can be made dependent on whether the device has issued a trip sig-nal. In this situation, messages are not reported, if one or more protective functionshave picked up on a fault, but a trip signal has not been issued yet by the device be-cause the fault was cleared by another device (for instance, in another line). Thesemessages are then limited to faults in the line to be protected.
Figure 2-4 shows the logic diagram for this function. When the relay drops off, station-ary conditions (fault display on every pickup/on trip only; trip/no trip) decide whetherthe new fault will be stored or reset.

2.1.3 Power System Data 1
The device requires certain basic data regarding the protected equipment, so that thedevice will be compatible with its desired application. Phase sequence data, nominalsystem frequency data, CT&PT ratios and their physical connections, as well as,breaker operating times and minimum current thresholds are selected in the Power System Data 1 display.
To modify these settings from the front of the device, the user should press the keyand wait for the MAIN MENU to appear. From the MAIN MENU, the user should use the
key to select Settings, and then use the key to navigate to the SETTINGSdisplay. To obtain the P.System Data1 display, the user should use the key toselect P.System Data1 in the SETTINGS display, and then press the key.
To modify settings associated with Power System Data 1 using DIGSI® 4, the usershould double-click Settings, and then Power System Data 1, and the desiredselection options will be displayed. A dialog box opens under Power System Data 1 which contains the tabs “Power System”, “CT’s”, “VT’s” and “Circuit Breaker”. Inthese tabs individual settings are configured. Thus the following Subsections arestructured accordingly.
2.1.3.1 Power System
Nominal Frequency Address 0214 Rated Frequency corresponds to the frequency at which the pro-tected equipment operate. The setting is dependent on the model number of the relaypurchased, and must be in accordance with the nominal frequency of the power sys-tem.
Phase Sequence Address 0209 PHASE SEQ. is used to establish phase rotation. The default phasesequence is “A B C”. For systems that use a phase sequence of “A C B”, address0209 should be set accordingly. A temporary reversal of rotation is also possible usingbinary inputs (see Section 2.18).
Temperature Unit Address 0276 TEMP. UNIT allows you to display the temperature values either in de-gree Celsius or in degree Fahrenheit.

Polarity of CurrentTransformers
At address 0201 CT Starpoint, the polarity of the wye-connected current trans-formers is specified (see Figure 2-5 for options). Modifying this setting also results ina polarity reversal of the ground current inputs IN or INS.
Figure 2-5 Current Transformer Polarity
Voltage Connection Address 0213 VT Connection specifies how the voltage transformers are connect-ed. When the voltage transformers are connected in a wye configuration, address0213 is set at Van, Vbn, Vcn. VT Connection = Vab, Vbc, VGnd meaning thattwo phase-to-phase voltages (V-connection) and Vgnd are connected. The latter set-ting is also selected when only two phase-to-phase voltage transformers are utilizedor when only the displaced voltage (zero sequence voltage) is connected to the de-vice.
7SJ64 features 4 voltage measuring inputs which enable further options besides theabove mentioned connection types: VT Connection = Van,Vbn,Vcn,VGn is se-lected if the three phase voltages in wye-connection and Vgnd are connected to thefourth voltage input of the device. Select VT Connection = Van,Vbn,Vcn,VSy ifthe fourth voltage input is used for the synchronizing function.
Units of Length Address 0215 Distance Unit corresponds to the units of length (km or Miles) ap-plicable to fault locating. If a fault locator is not included with the device, or if the faultlocating function is disabled, this setting has no effect on operation of the device.Changing the length unit will not result in an automatic conversion between the sys-tems. Such conversions must be entered at the appropriate addresses.
ATEX100 Parameter 0235A ATEX100 allows to fulfil the requirements for the protection of haz-ardous-duty motors for thermal replicas. Set this parameter to YES to save all thermalreplicas of 7SJ62/63/64 in the event of a power supply failure. After the supply voltagehas been restored the thermal replicas will resume operation using the stored values.Set the parameter to NO to reset the calculated overtemperatures of all thermal repli-cas to zero if the power supply fails.
Ground FaultProtection
With Parameter 0613A 50N/51N/67N w. You can specify whether the ground faultprotection function operates with measured values (Ignd (measured)) or with thevalues calculated from the three phase currents (Ignd (measured)) .
In the first case the measured quantities applying at the fourth current input are eval-uated, the latter case calculates the summation current from the three phase current

inputs. If the device features a sensitive ground current input (measuring range startsat 1 mA), the ground fault protection generally uses the calculated quantity 3I0.
2.1.3.2 Current Transformers (CT’s)
CT’s Nominal Val-ues
At addresses 0204 CT PRIMARY and 0205 CT SECONDARY, information is enteredregarding the primary and secondary ampere ratings of the current transformers. It isimportant to note that the primary ampere rating of the current transformers is basedon the actual tapped connection of the current transformers’ secondary winding (i.e.for a 1200/5 ampere multi-ratio current transformer connected at a 600/5 ampere tap,the user should enter a value of 600 for CT PRIMARY and a value of 5 for CT SEC-ONDARY). It is also important to ensure that the rated secondary current of the currenttransformer matches the rated current of the device, otherwise the device will incor-rectly calculate primary amperes.
Addresses 0217 Ignd-CT PRIM and 0218 Ignd-CT SEC provide the device withinformation on the primary and secondary rated current of the ground CT. In case ofa normal connection (starpoint current connected to Ignd-transformer)0217 Ignd-CT PRIM and 0204 CT PRIMARY must be set to the same value.
If the device is equipped with a sensitive ground fault current input, parameter 0218 Ignd-CT SEC is preset to 1 A. In this case the setting cannot be modified.
2.1.3.3 Voltage Transformers (VT’s)
VT’s Nominal Val-ues
At addresses 0202 Vnom PRIMARY and 0203 Vnom SECONDARY, information is en-tered regarding the rated primary nominal voltage and rated secondary nominal volt-ages (L-L) of the connected voltage transformers.
VT’s Ratio Address 0206A Vph / Vdelta corresponds to the factor by which the secondaryphase-to-ground voltage must be adjusted relative to the secondary displacementvoltage (zero sequence voltage), and only applies in situations where the displace-ment voltage is actually measured by the device as opposed to calculated by the de-vice.
If the voltage transformer set provides open delta windings and if these windings areconnected to the device, this must be specified accordingly in address 0213 (seeabove margin heading “Voltage Connection“). The relationships between the second-ary device input voltages and the primary phase-to-ground and displacement voltagesare given as follows:
For the secondary input voltages representing phase-to-phase voltages:
For the secondary input voltage representing displacement voltage:
Vsec-input Vprim-φφVT Ratio------------------------ 3 Vprim-φg
VT Ratio------------------------⋅= =
Vsec-input 3 Vprim-dispVT Ratio
----------------------------×=
28 7SJ62/63/64 ManualC53000-G1140-C147-1
General
Since the per unit base values of the phase-to-ground voltage and the displacementvoltage are equivalent, Vsec-input / Vprim-φg should equal Vsec-input / Vprim-disp.To compensate for the voltage transformer connection, the device must adjust thesecondary phase-to-ground voltage upward by a factor of √3. Therefore, in this case,address 0206A Vph / Vdelta would be set at 1.73 (= √3).
For situations where displacement voltage is measured by the device and other typesof voltage transformer connections are utilized, the setting at address 0206A shouldbe modified accordingly.
2.1.3.4 Circuit Breaker (CB)
Trip and CloseCommand Duration
Address 0210A TMin TRIP CMD is used to set the minimum time the tripping con-tacts will remain closed. This setting applies to all protective functions that initiate trip-ping.
Address 0211A TMax CLOSE CMD is used to set the maximum time the closing con-tacts will remain closed. This setting applies to the integrated reclosing function andmust be long enough to allow the circuit breaker contacts to reliably engage. An ex-cessive duration causes no problem since the closing command is interrupted in theevent another trip is initiated by a protective function.
Current Flow Moni-toring
Address 0212 BkrClosed I MIN corresponds to the threshold value of the integrat-ed current flow monitoring system. This setting is used by several protective functions(e.g., voltage protection with current supervision, breaker failure protection, overloadprotection, and restart block for motors). If the threshold value set at address 0212 isexceeded, the circuit breaker is considered closed.
The threshold value setting applies to all three phases, and takes precedence over allother protective functions.
With regard to breaker failure protection, the threshold value must be set at a level be-low the minimum fault current for which breaker failure protection must operate. Onthe other hand, the current threshold should not be set more sensitive than necessaryto avoid extended resetting times on transient phenomena of the current transformersafter interruption of high short–circuit currents. A setting of 10% below the minimumfault current for which breaker failure protection must operate is recommended.
When using the device for motor protection, overload protection, and restart blocking;the protective relay can distinguish between a running motor and a stopped motor, aswell as take into account the varying motor cool-down behavior. Under this application,the set value must be lower than the minimum no-load current of the motor.

2.1.4 Waveform Capture
The 7SJ62/63/64 relay is equipped with an oscillographic data saving feature. Themomentary values for the measurement quantities
Ia, Ib, Ic, IG, and INs, and Va, Vb, Vc, 3V0 and VSYN (only 7SJ64)
(voltages depending on the connection) are scanned at intervals of 1.04 ms for 60 Hz(1.25 ms for 50 Hz) and stored in a revolving buffer (16 samples per cycle). For a fault,the data are stored for an adjustable period of time, but not more than 5 seconds. Upto 8 fault records can be recorded in this buffer. The memory is automatically updatedwith every new fault, so no acknowledgment for previously recorded faults is required.Waveform capture can also be started with protection pickup, via binary input, via PC-interface, or SCADA.
Using the PC-interface or the rear service port, data can be retrieved by a personalcomputer and processed, using the protective data processing program DIGSI® 4,and the graphics program DIGRA® 4. DIGRA® 4 graphically prepares the data gener-ated during the fault, and calculates additional quantities, such as impedance or rmsvalues, from the delivered measured values. The currents and voltages can be repre-sented as primary or secondary quantities. In addition, relay sequence of events sig-nals are recorded as well.
Fault data may be retrieved via the serial interface of a PC. Data evaluation is per-formed by the PC using the respective programs. For this, the currents and voltagesare related to their maximum values, are standardized to the nominal value, and pre-pared for graphical display. Additionally, events such as the pickup of a relay elementor the initiation of a trip signal can be displayed as well.
If configured in SCADA, data are transferred automatically to the SCADA computer.
Programming Settings
Waveform Capture Waveform capture of faults is executed only when Address 0104 OSC. FAULT REC.is set for Enabled. Other settings pertaining to waveform capture are found underthe OSC. FAULT REC. sub-menu of the SETTINGS menu.
The trigger for an oscillographic record and the criterion to save the record are deter-mined with the setting of Address 0401 WAVEFORMTRIGGER. With the setting Save w. Pickup, the trigger and the criterion for saving are the same – the pickup of aprotective element. Another option for Address 0401 is Start w. TRIP. A trip com-mand issued by the device is both the trigger and the criterion to save the record withthis setting. The final — and more commonly used — option for Address 0401 is Save w. TRIP. The trigger under this setting is the pickup of a protective element (firstelement to pick up) and saving of the waveforms occurs only if the device issues a tripcommand. Each setting for Address 0401 has specific advantages. The choice de-pends primarily on the expected duration of faults, the time period of a complete faultduration that is of most interest (e.g. inception or clearing), and the frequency of wave-form capturing that is to be expected.
There are two options available for the coverage of oscillographic recording. The se-lection is made under Address 0402 WAVEFORM DATA and is based on the user’spreference for recording events that occur while automatic reclosing is performed bythe device. With the setting Fault event, waveform capturing occurs each timethe recording trigger and save criterion are established. If automatic reclosing in thedevice is employed, the second option Pow.Sys.Flt. can be selected if desired.
317SJ62/63/64 ManualC53000-G1140-C147-1
Functions
With this setting, the entire course of a fault - from inception, through reclosing, toclearing - is captured. This option provides detailed data for analysis of the entire faulthistory; however, the option also requires considerable memory for recording duringdead times.
An oscillographic record includes data recorded prior to the time of trigger, and dataafter the dropout of the recording criterion. The user determines the length of pre-trig-ger time and post-dropout time to be included in the fault record with the settings inAddress 0404 PRE. TRIG. TIME and Address 0405 POST REC. TIME. The set-tings depend on Address 0401 and the information desired. For example, consider thetrigger being a pickup of a protective element and the save criterion being a trip. Thepre-trigger time is set based on the amount of pre-fault information that is desired. Thepost-dropout time is set based on the amount of information desired after clearing (e.g.checking for restrikes).
The maximum length of time of a record is entered in Address 0403 MAX. LENGTH. The largest value here is 5 seconds. A total of 8 records can be saved. However thetotal length of time of all fault records in the buffer may not exceed 5 seconds. Oncethe capacity of the buffer is exceeded the oldest fault is deleted, whereas the new faultis saved in the buffer.
An oscillographic record can be triggered and saved by a change in status of a binaryinput or via the operating interface connected to a PC. The trigger is dynamic. Thelength of a record for these special triggers is set in Address 0406 BinIn CAPT.TIME (upper bound is Address 0403). Pre-trigger and post-dropout settings inAddresses 0404 and 0405 do not apply. If Address 0406 is set for “∞,” then the lengthof the record equals the time that the binary input is activated (static), or the MAX. LENGTH setting in Address 0403, whichever is shorter.

2.1.5 Setting Groups
Purpose of SettingGroups
A setting group is nothing more than a collection of setting values to be used for a par-ticular application. In the 7SJ62/63/64 relay, 4 independent setting groups (A ~ D) arepossible. The user can switch back and fourth between setting groups locally, via bi-nary inputs (if so configured), via the operator or service interface using a personalcomputer, or via the system interface. For reasons of safety it is not possible to changebetween setting groups during a power system fault.
A setting group includes the setting values for all functions that have been selected asEnabled during configuration (see Chapter 5). While setting values may vary amongthe 4 setting groups, the selected functions of each setting group remain the same.
Multiple setting groups allows a specific relay to be used for more than one application.While all setting groups are stored in the relay, only one setting group may be activeat a given time.
If multiple setting groups are not required, Group A is the default selection, and thefollowing paragraph is not applicable.
If multiple setting groups are desired, address 0103 Grp Chge OPTION must be setto Enabled in the relay configuration. For the setting of the function parameters, youconfigure each of the required setting groups A to D, one after the other. A maximumof 4 is possible. Please refer to the DIGSI® 4–System Manual, Order No. E50417–H1176–C151 to learn how to copy setting groups or reset them to their status at deliv-ery and also what you have to do to change from one setting group to another.
Subsection 3.1.2 tells you how to change between several setting groups externallyvia binary inputs.

2.1.6 Power System Data 2
General protective data (P.SYSTEM DATA2) includes settings associated with allfunctions rather than a specific protective or monitoring function. In contrast to theP.SYSTEM DATA1 as discussed in Sub-section 2.1.3, these settings can be changedover with the setting groups. To modify these settings, the user should select SET-TINGS menu option Group A (setting group A), and then P.System Data2.
The other setting groups are Group B, Group C, and Group D, as described inSubsection 2.1.5.
Definition ofNominal RatedValues
At addresses 1101 FullScaleVolt. and 1102 FullScaleCurr., the referencevoltage (phase-to-phase) and reference current (phase) of the protected equipment isentered (e.g., motors). These values do not effect pickup settings. If these referencevalues match the primary VT’s and CT’s, they correspond to the settings in address0202 and 0204 (Subsection 2.1.3). They are generally used to show values in refer-ence to full scale. For example, if a CT ratio of 600/5 is selected and the full load cur-rent of a motor is 550 amps, a value of 550 amps should be entered forFullScaleCurr. if monitoring in reference to full load current is desired. 550 ampsare now displayed as 100 % in the percentage metering display.
Ground ImpedanceRatios (only forfault location)
The ground impedance ratios must be entered to facilitate line fault location. At ad-dress 1103 RG/RL Ratio, the resistance ratio of the line is entered, and at address1104 XG/XL Ratio, the reactance ratio of the line is entered. The ground impedanceratios are calculated separately, and do not correspond to the real and imaginary com-ponents of Z0/Z1. Therefore, no complex calculations are necessary. The ground im-pedance ratios are obtained from conductor data using the following formulas:
Resistance Ratio: Reactance Ratio:
Where
R0 = Zero sequence resistance of the line
X0 = Zero sequence reactance of the line
R1 = Positive sequence resistance of the line
X1 = Positive sequence reactance of the line
The ground impedance ratios may be calculated using the impedance values for theentire line or the impedance per mile values associated with the conductor, since the

length of the line is factored out in the formulas above.
Calculation example:

R1/s = 0.39 Ω/mileX1/s = 0.55 Ω/mile Positive sequence impedance
R0/s = 1.42 Ω/mileX0/s = 2.03 Ω/mile Zero sequence impedance
For ground impedance ratios, the following emerge:
These values are set at addresses 1103 and 1104 respectively.
Reactance Setting(only for fault loca-tion)
The reactance setting must be entered if line fault location is desired. The reactancesetting enables the protective relay to report fault location in terms of distance.
The reactance value is entered as a secondary value at address 1105 in ohms permile if address 0215 is set to Miles, or at address 1106 in ohms per kilometer if ad-dress 0215 is set to Kilometers (see Subsection 2.1.3 under “Units of Length”). If thesetting of address 0215 is modified after entry of a reactance value at address 1105or 1106, the reactance value must be modified and reentered accordingly.
The calculation of primary ohms in terms of secondary ohms is accomplished usingthe following formula:
Because the reactance value must be entered in secondary ohms per unit length, theformula above must be used to convert primary ohms per unit length into secondaryohms per unit length as shown below:
Example calculation:
The same example used to illustrate calculation of ground impedance ratios will beused to illustrate calculation of the reactance setting, with the following additional dataon the current transformers and voltage transformers:

This value is entered at Address 1106.
Recognition ofRunning Condition(only for motors)
Address 1107 I MOTOR START, is used for motor protection applications and corre-sponds to the minimum starting current of the protected motor. The current setting en-tered at address 1107 enables the device to determine if the protected motor is instart-up mode, thus allowing the device to properly perform the start-up time monitor-ing and overload protection functions.
In determining the setting for address 1107, the following should be considered:
• A setting must be selected that is lower than the actual motor start-up current underall load and voltage conditions.
• Because the thermal cure of the overload protection is “frozen” (held constant) dur-ing motor start-up, the setting must be high enough to allow operation of the over-load protection at higher load current levels.
2.1.6.1 Settings
In the list below, the setting ranges and default setting values are for a device with anominal current rating IN = 1 A. Consider the current transformer ratios when settingthe device with primary values
For a nominal current rating IN = 5 A:

2.2 Overcurrent Protection (50, 50N, 51, 51N)
General Time-overcurrent protection is the main protective function of the 7SJ62/63/64 relay.It may be enabled or disabled for phase or ground faults, and may be configured withvarious time-overcurrent characteristic curves.
There are four definite time (Instantaneous elements with optional timers) and two in-verse time-overcurrent elements in the device. The definite time elements include twophase elements and two ground elements. The definite time (Instantaneous) phase el-ements are designated 50-2 and 50-1, whereas the definite time (Instantaneous)ground elements are designated 50N-2 and 50N-1. The inverse time elements includea phase element designated as 51 and a ground element designated as 51N.
The overcurrent protection for the ground current can operate either using measuredvalues Ignd or the quantities 310 calculated from the three phase currents dependingon the parameter 0613A 50N/51N/67N w.Devices featuring a sensitive ground cur-rent input, however, use generally the calculated quantity 3I0.
All overcurrent elements, inverse and definite time, enabled in the device may beblocked via the automatic reclosure function (depending on the cycle) or via an exter-nal signal to the binary inputs of the device. Removal of the external signal to the bi-nary input will re-enable these elements. Also, a feature described as Manual CloseMode can be configured to improve fault clearing times associated with Switch-on-to-Fault Conditions. Under this situation, the time delay may be bypassed for one of thethree time-overcurrent phase elements and one of the three time-overcurrent groundelements via an impulse from the external control switch, thus resulting in high speedtripping. This impulse is prolonged by a period of 300 ms. The phase and ground ele-ments utilized for high speed tripping in this situation are selected at addresses 1213and 1313 respectively.
The automatic reclosure function may also initiate the immediate tripping for the over-current stages and high-current stages depending on the cycle.
Pickup and delay settings may be quickly adjusted to system requirements via ColdLoad Pickup function (see Section 2.4).
Tripping by the 50-1, 51, 50N-1, and 51N elements may be blocked for inrush condi-tions by utilizing the inrush restraint feature.

Currents above the pickup values are detected and recordedwithin the protective relay. After the user-configured time delay has elapsed, a trip sig-nal is issued.

Currents above the pickup values are detected and recordedwithin the protective relay. After the user-configured time delay has elapsed, a trip sig-nal is issued.
If the inrush restraint feature is enabled (see below), and an inrush condition exist, notripping takes place, but a message is recorded and displayed indicating when theovercurrent element time delay elapses.
Different messages are recorded and displayed appear depending on whether trippingtakes place or the time delay expires without tripping.
The dropout value of the definite time, time-overcurrent elements is roughly equal to95 % of the pickup value for currents greater than or equal to 30 % of the nominal cur-rent of the device.
These stages may be blocked by the automatic reclosure function.

2.2.1.2 Inverse Time-Overcurrent Protection (51, 51N)
Inverse time-overcurrent protection, the 51 and 51N relay elements may contain IECcharacteristic curves or ANSI characteristic curves depending on the model ordered.A user-specified curve may also be applied to the inverse-overcurrent relay elements.The curves and associated formulas are given in Technical Specifications (Figures 4-1 to 4-6 in Section 4.3). During configuration of the 51 and 51N characteristic curves,the definite time relay elements (50-2, 50-1, 50N-2, and 50N-1) are enabled (see Sub-section 2.2.1.1).
Pickup and Trip-ping
Each phase and ground current is separately compared with the pickup values of the51 and 51N relay elements. When the current in the 51 and 51N relay elements ex-ceeds the corresponding pickup value by a factor of 1.1, the element picks up and amessage is displayed and recorded within the device. Pickup of a 51 or 51N relay el-ement is based on the rms value of the fundamental harmonic. When the 51 and 51Nelements pickup, the time delay of the trip signal is calculated using an integratedmeasurement process. The calculated time delay is dependent on the actual fault cur-

If the inrush restraint feature is enabled, and an inrush condition exist, no trippingtakes place, but a message is recorded and displayed indicating when the overcurrentelement time delay elapses.
These stages can be blocked by the automatic reclosing function.
The characteristic curves of the 51 and 51N relay elements may be selected indepen-dently of each other. In addition, pickup, time multipliers, and time dials for the 51 and51N elements may be individually set.

Dropout for ANSIand IEC Curves
For ANSI and IEC curves you can specify whether the dropout of a stage, after it hasfallen below a threshold, takes places instantaneously or via disk emulation. Instanta-neously means that the dropout of a stage which has picked up is performed as soonas the value falls below approximately 95 % of the pickup value. The timer will startagain for all new pick-ups.
Dropout of an element occurs when the current decreases to about 95 % of the pickupvalue if instantaneous reset is selected, or 90 % of the pickup value if disk emulationis selected. When instantaneous reset is selected, reset of the element occurs withoutdelay. When disk emulation is selected, reset occurs just as it would for an electrome-chanical relay utilizing an induction disk.
For disk emulation, the reset process begins after fault current is interrupted. Resetcorresponds to the unwinding of an induction disk. A subsequent pickup of the deviceelement prior to full reset will result in a reduced tripping time delay. The reduced trip-ping time delay will be based on the degree to which the device had reset when thesubsequent pickup occurred. When the current in the relay element is between 90 %and 95 % of the pickup value following dropout, neither disk movement in the trippingor reset direction is simulated. When the current in the relay elements falls below 5 %of the pickup value, disk emulation is canceled and full reset takes place.
Disk emulation offers advantages when the inverse time, time-overcurrent relay ele-ments must be coordinated with conventional electromechanical overcurrent relays lo-cated toward the source.
User SpecifiedCurves
When user specified curves are utilized, the time-current characteristic curve may bedefined point by point. Up to 20 pairs of values (current, time) may be entered. Therelay element then approximates the curve using linear interpolation.
When utilizing user specified time-current curves, the reset curve may user specifiedas well. See reset for ANSI and IEC characteristics in the function description. If userspecified reset curves are not utilized, the relay element drops out when current de-creases to about 95 % of the relay element’s pickup value, and immediate reset takesplace.

2.2.1.3 Dynamic Cold Load Pick-up Function
With the dynamic cold load pick-up feature, it is possible to dynamically increase thepickup values of the directional and non-directional overcurrent relay elements whendynamic cold load pickup conditions are anticipated (i.e. after a long period of zerovoltage). By allowing pickup settings to increase dynamically, it is not necessary to in-corporate dynamic cold load capability in the normal pickup settings, and directionaland non-directional overcurrent protection may be set more sensitive.
This dynamic pick-up value changeover is common to all overcurrent stages and is de-scribed in Section 2.4. The alternative pick-up values can be set individually for eachstage of the time overcurrent protection.

2.2.1.4 Inrush Restraint
When the 7SJ62/63/64 relay is installed to protect a power transformer, large magne-tizing inrush currents will flow when the transformer is energized. These inrush cur-rents may be several times the nominal transformer current, and, depending on thetransformer size and design, may last from several milliseconds to several seconds.
Although pickup of the relay elements is based only on the fundamental harmoniccomponent of the measured currents, false device pickup due to inrush is still a poten-tial problem since, depending on the transformer size and design, the fundamentalharmonic comprises a large component of the inrush current.
The 7SJ62/63/64 features an integrated inrush restraint function that may be utilizedwhen the device is installed at or near a transformer. It supervises the “normal” trippingof all directional and non-directional overcurrent relay elements with the exception ofthe 50-2, 50N-2, 67-2 and 67N-2 relay elements. For example, when a transformer isenergized the current levels may exceed the normal pickup of the overcurrent ele-ments set in the device. If inrush conditions are identified (the 2nd harmonic contentof current exceeds the value of setting at address 2202 2nd HARMONIC), special in-rush messages are created within the device that will block tripping of the overcurrentelements. Note, that only the tripping elements are affected by harmonic inrush detec-tion, the pickup values and corresponding timers continue to operate normally. If in-rush conditions are still present after the tripping time delay has elapsed, a corre-sponding message is displayed and recorded, but the overcurrent tripping is blocked.(see Figures 2-8 to 2-11).
Inrush current contains a relatively large second harmonic component which is nearlyabsent during a short-circuit fault. Inrush current detection, therefore, is based on theevaluation of the second harmonic component present during inrush conditions. Forfrequency analysis, digital filters are used to conduct a Fourier analysis of all threephase currents and the ground current. As soon as the second harmonic componentof the current flowing in a specific phase or ground relay element exceeds a set value,tripping is blocked for that element (does not apply to 50-2, 50N-2, 67-2, and 67N-2elements). Since quantitative analysis of the harmonic components of the current flow-ing through a specific relay element cannot be completed until a full cycle of inrush cur-rent has been measured, inrush restraint blocking, and the associated inrush detec-tion message, is automatically delayed by one cycle. It is important to note, however,that the tripping time delays associated with the relay elements are started immediate-ly after pickup of the relay element, even if the inrush conditions are detected. If inrushblocking drops out during the time delay, tripping will occur when the time delay of theelement elapses. If inrush blocking drops out after the time delay has elapsed, trippingwill occur immediately. Therefore, utilization of the inrush restraint feature will not re-sult in any additional tripping delays. If a relay element drops out during inrush block-ing, the associated time delay will reset.
Cross Blocking Since inrush restraint operates individually for each phase, inrush restraint will notblock tripping in situations where a power transformer is energized into a single-phasefault and inrush currents are detected on the unfaulted phases. This feature providesmaximum protection, however, inrush restraint can be configured to allow inrush de-tection on one phase to block tripping by the elements associated with the other phas-es. This is referred to as cross-blocking and can be enabled at address 2203. Inrushcurrents flowing in the ground path will not cross-block tripping by the phase elements.
The cross-blocking function may also be limited to a particular time interval, which canbe set at address 2204. After expiration of this time interval, the cross-blocking func-tion will be disabled.
Functions
The inrush restraint has an upper limit. It no longer takes effect when a (configurable)current value is surpassed since, in this case, it can only be an internal high-currentfault.
Figure 2-12 shows the logic diagram of the inrush restraint including cross-blocking.

2.2.1.5 Reverse Interlocking Bus Protection
Application Exam-ple
The pickup of a time-overcurrent relay element may be blocked via binary inputs. Atthe users option, the binary inputs can be set up to block tripping when DC voltage isapplied or when DC voltage is removed. Reverse interlocking allows for faster protec-tion by eliminating the need for time-current coordination. Reverse interlocking is oftenused, for example, at generating stations in applications where a station supply trans-former supplied from the transmission grid serves internal loads of the generation sta-tion via a medium voltage bus with multiple feeders (see Figure 2-13).
When the 7SJ62/63/64 relay is used as the source-side relay in a reverse interlockingscheme, a short time delay must be set for the 50-2 element so that a load-side relayhas the chance to block tripping (Figure 2-13). The load-side relay should pickup im-mediately for down-line faults so that a blocking signal is immediately sent to thesource-side relay’s binary inputs. The load-side protective device can then initiate atime delayed trip, as long as the time delay is less than the time delay settings of thesource-side relay’s 50-1 and 50N-1 relay elements and the time multiplier settings ofthe source-side relay’s 51 and 51N relay element. The source side relay’s 50-1, 50N-1, 51 and 51N relay elements will provide redundant protection against faults in theload side relay’s zone of protection since their associated time delay settings aregreater than the load side relay’s time delay setting.
Pickup messages generated by the load-side relay are passed to a binary input of thesource-side relay as input message “>50-2 block.”.

2.2.2 Programming Time-Overcurrent Settings
Selecting the time-overcurrent protection in DIGSI® 4 opens a dialog box containingthe tabs “General”, “50”, “51”, “50N”, “51N” and “Inrush Restraint” in which you canmodify the individual settings. The setting notes in this manual are structured accord-ingly.
2.2.2.1 General
50/51 The functions associated with time-overcurrent protection were established duringconfiguration of protective functions (Section 2.1.1) at address 0112 Charac. Phase. If address 0112 was set to Definite Time, then only the settings for thedefinite-time elements are available. The selection of TOC IEC or TOC ANSI makesavailable additional inverse characteristics. The superimposed high-current stage 50-2 is available in all these cases.
At address 1201 FCT 50/51, phase time-overcurrent protection may be switched ONor OFF.
50N/51N The functions associated with time-overcurrent protection were established duringconfiguration of protective functions (Section 2.1.1) at address 0113. If address 0113was set equal to Charac. Ground = Definite Time, then only the settings for thedefinite-time elements are available. Inverse characteristics may be available in addi-tion. The superimposed high-set stage 50N-2 is available in all these cases.
Depending on the parameter 0613A 50N/51N/67N w.the overcurrent protection forground currents can either operate with measured values IGnd or with the quantities3I0 calculated from the three phase currents. Devices featuring a sensitive ground cur-rent input, however, generally use the calculated quantity 3I0.
The time-overcurrent protection for ground currents can be switched ON or OFF in ad-dress 1301 FCT 50N/51N independent of the time-overcurrent protection for phasecurrents.
For ground faults characteristic, pick-up value and delay time can be set separatelyfrom those of the phase branches. This allows to use a different grading with shorterdelays and more sensitive settings for ground faults.
Manual Close Mode(Phase, Ground)
When a circuit breaker is closed into a faulted line, a high speed trip by the circuitbreaker is often desired. The manual closing feature is designed to remove the delayfrom one of the time-overcurrent elements when a circuit breaker is manually closedinto a fault. The time delay may be bypassed for one of the three time-overcurrentphase elements and one of the three time-overcurrent ground elements via an impulsefrom the external control switch, thus resulting in high speed tripping. This impulse isprolonged by a period of 300 ms. Address 1213A MANUALCLOSEMODE can be setsuch that the delay is defeated for the 50-2 element, the 50-1 element, the 51 element,or none of the elements (Inactive). Defeating the delay on just one of the three el-ements allows control over what level of fault current is required to initiate high speedtripping of a circuit breaker that is closed into a fault.
Accordingly, address 1313A MANUALCLOSEMODE is taken into account for the groundpath. It specifies for the phase and ground which pick-up value takes effect with whatdelay time if the circuit breaker is closed manually.

External controlswitch
If the manual closing signal is not from a 7SJ62/63/64, that is, neither via the built-inoperator interface nor via a series interface, but, rather, directly from a control switch,this signal must be passed to a 7SJ62/63/64 binary input, and configured accordinglyso that the element selected for high speed tripping will be effective.
Internal controlfunction
The manual closing information must be routed via CFC (interlocking task-level) usingthe CMD_Information block, if the internal control function is used (see Figure 2-14).

Subsec-tion 2.2.2.6 shows the characteristic values of the inrush restraint function.
2.2.2.2 Definite-Time Overcurrent Protection (50-2, 50-1)
50-2 Relay Element The pickup and delay of the 50-2 relay element are set at addresses 1202 50-2 PICKUP and 1203 50-2 DELAY respectively. The 50-2 relay element is typically uti-lized for protection against high magnitude faults. For this reason, the relay elementpickup is often set high while the delay is set short. It is always important to set thepickup and delay such that operation of the 50-2 element will coordinate with otherprotective equipment in the system.
Below is an example of how a 50-2 relay element might be set to protect a powertransformer in a radial distribution system against high magnitude internal faults:

Functions
The minimum pickup setting for the 50-2 element can be governed by a single inequal-ity:
If the pickup of the 50-2 relay element is set according to the inequality above, the 50-2 element will never pickup for a fault beyond the transformer’s low-side bushings,even if changing system conditions increase the high side fault MVA. Using the ine-quality above as a guide, a setting of 10.00 amperes is chosen for the 50-2 element.
At address 1203, a short time delay should be entered to prevent inrush currents frominitiating false trips.
For motor protection, the 50-2 relay element must be set smaller than the smallestphase-to-phase fault current and larger than the largest motor starting current. Sincethe maximum motor starting current is generally on the order of 1.6 times the nominalmotor current, the 50-2 phase element should be set as follows:
The potential increase in starting current caused by overvoltage conditions is alreadyaccounted for by the 1.6 factor. The 50-2 phase element may be set with no delaysince, unlike the transformer, no saturation of the cross reactance occurs in a motor.
If the reverse interlocking principle is used (see Subsection 2.2.1.5), the 50-2 elementcan be employed in a high speed bus protection scheme. With a brief safety delay en-tered at address 1203 (50 ms), the 50-2 element can be blocked for faults beyond thebus feeder breakers. The 50-1 element or 51 element will serve as redundant protec-tion for the bus. The pickup values of both the 50-2 unit and the 50-1 or 51 unit are setequal to each other. The time delay associated with the 50-1 or 51 element is thentime-coordinated with the individual bus feeder devices.
The delay set at address 1203 is in addition to the 50-2 pickup time. The delay of the50-2 element may be set to ∞. The 50-2 element will then pickup and generate a mes-sage, but will never trip. If the 50-2 element is not required at all, then the pickup valueshould be set to ∞, thus preventing pickup, trip, and the generation of a message.
50-1 Relay Element The pickup value of the 50-1 relay element (set at address 1204 50-1 PICKUP)should be set above the maximum anticipated load current. Pickup due to overloadshould never occur since the 50-1 relay element is designed only for fault protection.For this reason, a setting equal to 120 % of the expected peak load is recommendedfor line protection, and a setting equal to 140 % of the expected peak load is recom-mended for transformers and motors.
If the 7SJ62/63/64 relay is used to protect transformers with large inrush currents, theenergization stabilization feature may be used to prevent a false trip of the 50-1 relay

element. The configuration data for the inrush restraint feature is programmed at ad-dress block 22 (see Subsection 2.9.2).
The delay of the 50-1 element is set at address 1205 50-1 DELAY and should bebased on system coordination requirements.
The delay set at address 1205 is in addition to the 50-1 element’s pickup time. Thedelay of the 50-1 element may be set to ∞. The 50-1 element will then pickup and gen-erate a message, but will never trip. If the 50-1 element is not required at all, then thepickup value should be set to ∞, thus preventing pickup, trip, and the generation of amessage.
Interaction with Au-tomatic ReclosingEquipment
When reclosing occurs, it is desirable to have high speed protection against temporaryfaults. If the fault still exists after the first reclose, the 50-2 elements can be blockedand the 50-1 and/or 51 elements will provide time delay tripping. At address 1214A50-2 active, it can be specified whether or not the 50-2 elements should be super-vised by the status of an internal or external automatic reclosing device. If address1214A is set to With 79 Active, the 50-2 elements will not operate unless auto-matic reclosing is not blocked. If address 1214A is set to Always, the 50-2 elementswill always operate.
The integrated automatic reclosing function of 7SJ62/63/64 also provides the optionto individually determine for each time overcurrent stage whether tripping or blockingis to be carried out instantaneously or with time delay, unaffected by the AR (see Sub-section 2.13.1.3).
2.2.2.3 Inverse-Time Overcurrent Protection (51)
51 Relay ElementWith IEC or ANSICurves
Having set TOC IEC or TOC ANSI when configuring the protection functions (Subsec-tion 2.1.1) in address 0112 Charac. Phase, also the parameters for the inversecharacteristics are available.
Having set TOC IEC in address 0112 Charac. Phase, specify the desired IECcurve (Normal Inverse, Very Inverse, Extremely Inv. or Long Inverse)in address 1211 51 IEC CURVE. If TOC ANSI was selected in address 0112Charac. Phase, specify the desired ANSI curve (Very Inverse,Inverse, Short Inverse, Long Inverse, Moderately Inv., Extremely Inv. or Definite Inv.) in address 1212 51 ANSI CURVE.
Pickup of the 51 relay element will occur for currents greater than or equal to 110 %of the 51 element’s pickup value, and may or may not occur for currents between100 % and 110 % of the 51 element’s pickup value. Dropout of the 51 relay elementoccurs when the current decreases to 95 % of the 51 element’s pickup value. Select-ing the option Disk Emulation in address 1210 51 Drop-out, the dropout is per-formed according to the dropout characteristic as described in Subsection 2.2.1.2.
The pickup of the 51 element is set at address 1207 51 PICKUP. As is the case forthe 50-1 relay element, the pickup value of the 51 relay element should be set abovethe maximum anticipated load current. Pickup due to overload should never occursince the 51 relay element is designed only for fault protection. For this reason, a set-ting equal to 120 % of the expected peak load is recommended for line protection, anda setting equal to 140 % of the expected peak load is recommended for transformersand motors.

The associated time multiplier becomes accessible when selecting an IEC curve ataddress 1208 51 TIME DIAL and an ANSI curve at address 1209 51 TIME DIAL.It must be coordinated with the time grading of the network.
The time multiplication factor may be set to ∞. The 51 element will then pickup andgenerate a message, but will never trip. If the 51 element is not required at all, address0112 should set to Charac. Phase = Definite Time during protective functionconfiguration.
User SpecifiedCharacteristicCurves
If address 0112 Charac. Phase = User Defined PU or User def. Reset dur-ing configuration of the user-specified curve option, a maximum of 20 value pairs (cur-rent and time) may be entered at address 1230 51/51N to represent the time-currentcharacteristic curve associated with the 51 element. This option allows point-by-pointentry of any desired curve. This option allows point-by-point entry of any desiredcurve. If address 0112 was set to User def. Reset during configuration of theuser-specified curve option, additional value pairs (current and reset time) may be en-tered at address 1231 MofPU Res T/Tp to represent the reset curve associatedwith the 51 element.
Since the entered current values are rounded off in a certain grid system of the devicebefore the editing (see Table 2-4), we recommend the use of these exact values.
Current and time values are entered as multiples of the address 1207 and 1208 set-tings. Therefore, it is recommended that addresses 1207 and 1208 be initially set to1.00 to simplify the calculation of these ratios. Once the curve is entered, the settingsat addresses 1207 and 1208 may be modified if necessary.
Upon delivery of the device, all time values are set at ∞, preventing pickup of the de-vice from initiating a trip signal.
When entering a user-specified curve, the following must be observed:
− Enter the data points in ascending order. The time overcurrent functions will sort thedata points by current values in ascending order. The graphical representation dis-plays the data points in the order they are entered.
− As few as 10 pairs of numbers may be entered at the user’s option. Each unusedpair must then be marked as unused by entering “∞” as for the time and current val-ues. It is important to view the curve to ensure that it is clear and constant.
− The current values entered should be those from Table 2-4, along with the matchingtimes. Other values for MofPU are changed to the nearest adjacent value althoughthis is not indicated.

Overcurrent Protection (50, 50N, 51, 51N)
2.2.2.4 Programming Settings for Time-Overcurrent Ground Protection
General The functions associated with time-overcurrent protection were established duringconfiguration of protective functions (Section 2.1.1) at address 0113 Charac. Ground. If address 0113 was set equal to Definite Time, then only the settingsfor the definite-time elements are available. Inverse characteristics may be availablein addition. The superimposed high-set stage 50N-2 is available in all these cases.
At address 1301 FCT 50N/51N, ground time-overcurrent protection may be switchedON or OFF independent of the phase time-overcurrent protection.
Pickup values, time delays, and characteristic curves for ground protection are setseparately from the pickup values, time delays and characteristic curves associatedwith phase protection. Because of this, relay coordination for ground faults is indepen-dent of relay coordination for phase faults, and more sensitive settings can often beapplied to ground protection.
50N-2 Relay Ele-ment
The pickup and delay of the 50N-2 relay element are set at addresses 1302 50N-2 PICKUP and 1303 50N-2 DELAY respectively. The same considerations apply forthese settings as did for 50-2 settings discussed earlier.
The delay set at address 1303 is in addition to the 50N-2 element’s pickup time. Thedelay of the 50N-2 element may be set to ∞. The 50N-2 element will then pickup andgenerate a message, but will never trip. If the 50N-2 element is not required at all, thenthe pickup value should be set to ∞, thus preventing pickup, trip, and the generationof a message.
50N-1 Relay Ele-ment
The pickup value of the 50N-1 relay element (set at address 1304 50N-1 PICKUP)should be set below the minimum anticipated ground fault current in the relay’s zoneof protection.
If the 7SJ62/63/64 relay is used to protect transformers or motors with large inrush cur-rents, the energization stabilization feature may be used to prevent a false trip of the50N-1 relay element. It can be enabled or disabled for both the phase current and theground current in address 2201 INRUSH REST.. The characteristic values of the in-rush restraint are listed in Subsection 2.2.2.6.
The delay of the 50N-1 element is set at address 1305 50N-1 DELAY and should bebased on system coordination requirements.
The delay set at address 1305 is in addition to the 50N-1 element’s pickup time. Thedelay of the 50N-1 element may be set to ∞. The 50N-1 element will then pickup andgenerate a message, but will never trip. If the 50N-1 element is not required at all, thenthe pickup value should be set to ∞, thus preventing pickup, trip, and the generationof a message.
Interaction with Au-tomatic ReclosingEquipment
When reclosing occurs, it is desirable to have high speed protection against temporaryfaults. If the fault still exists after the first reclose, the 50N-2 elements can be blockedand the 50N-1 and/or 51N elements will provide time delay tripping. At address 1314A50N-2 active, it can be specified whether or not the 50N-2 elements should be su-pervised by the status of an internal or external automatic reclosing device. If address1314A is set to With 79 Active, the 50N-2 elements will not operate unless auto-matic reclosing is not blocked. If address 1314A is set to Always, the 50N-2 elementswill always operate.

Functions
The integrated automatic reclosing function of 7SJ62/63/64 also provides the optionto individually determine for each time overcurrent stage whether tripping or blockingis to be carried out instantaneously or with time delay, unaffected by the AR (see Sub-section 2.13.1.3).
2.2.2.5 Inverse-Time Overcurrent Protection (51N)
51N Relay Elementwith IEC or ANSICurves
Setting TOC IEC in address 0113 Charac. Ground when configuring the protectionfunctions (Subsection 2.1.1), also the parameters for the inverse characteristics areavailable. Set the desired IEC curve (Normal Inverse, Very Inverse, Extreme-ly Inv. or Long Inverse) in address 1311 51 IEC CURVE. Setting TOC ANSI in address 0113 Charac. Ground, specify the desired ANSI curve (Very Inverse,Inverse, Short Inverse, Long Inverse, Moderately Inv., Extremely Inv. or Definite Inv.) in address 1312 51 ANSI CURVE.
Pickup of the 51N relay element will occur for currents greater than or equal to 110 %of the 51N pickup value, and may or may not occur for currents between 100 % and110 % of the 51 element’s pickup value. Dropout of the 51N relay element occurswhen the current decreases to 95 % of the 51N element’s pickup value. If option Disk Emulation in enabled in address 1310 51 Drop-out, the dropout is performedaccording to the dropout characteristic as described in Subsection 2.2.1.2.
The pickup value of the 51N element is set at address 1307 51N PICKUP. As is thecase for the 50N-1 relay element, the pickup value of the 51N relay element should beset below the minimum anticipated ground fault current in the relay’s zone of protec-tion.
The 51N element time multiplication factor for an IEC curve is set at address 130851N TIME DIAL and in address 1309 51N TIME DIAL for an ANSI curve andshould be based on system coordination requirements.
The time multiplication factor may also be set to ∞. The 51N element will then pickupand generate a message, but will never trip. If the 51N element is not required at all,address 0113 should be set to Definite Time during protective function configura-tion (see Section 2.1.1).
2.2.2.6 Inrush Restraint
Inrush restraint will only operate, and is only accessible, if enabled at address 0122InrushRestraint during configuration of protective functions. If the function is notrequired, address 0122 should be set to Disabled. In address 2201 INRUSH REST.the function is switched ON or OFF jointly for the overcurrent stages 50-1 PICKUP, 51 PICKUP, 50N-1 PICKUP and 51N PICKUPON.
The inrush restraint is based on the evaluation of the 2nd harmonic present in the in-rush current. Upon delivery from the factory, the device is programmed to initiate in-rush restraint when the second harmonic component of the measured current exceeds15 % of the total current. This value is identical for all phases and ground, and may bemodified at address 2202. Under normal circumstances, this setting will not need tobe changed. However, in special situations, this setting may be as low as 12 %.
The effective duration of the cross-blocking 2203 CROSS BLK TIMER can be set toa value between 0 s (harmonic restraint active for each phase individually) and a max-

The maximum current where inrush restraint can operate is set at address 2205 I Max
2.2.3 Settings
In the list below, the setting ranges and default setting values for the pickup currentsare for a device with a nominal current rating IN = 1 A. For a nominal current rating IN= 5 A, multiply the Setting Options values and Default Setting values by 5. Considerthe current transformer ratios when setting the device with primary values.

2.3 Directional Overcurrent Protection (67, 67N)
General The 7SJ62/63/64 features directional overcurrent protection. Therefore, this devicecan be applied to systems where proper protection depends on knowing both the mag-nitude of the fault current and the direction of energy flow to the fault location. Direc-tional overcurrent protection requires that the device be connected to both currenttransformers and voltage transformers. The time-overcurrent protection (non-direc-tional) described in Section 2.2 may operate as overlapping back-up protection or maybe disabled. Additionally, the user may select between directional overcurrent protec-tion and non-directional overcurrent protection on a relay element by relay element ba-sis.
To better understand the benefits of directional overcurrent protection, consider theparallel transformers shown in Figure 2-17. These transformers are designated as Iand II and are supplied from a single source. For a fault internal to Transformer I, someof the fault current will flow from Bus A through Transformer I to the fault while the re-maining fault current flows from Bus A through Transformer II and Bus B to the fault.In order to avoid tripping out Bus B for this fault, the load side relays protecting Trans-former II must coordinate with the load side relays protecting Transformer I. Likewise,for a fault internal to Transformer II, some of the fault current will flow from Bus Athrough Transformer II to the fault while the remaining fault current flows from Bus Athrough Transformer I and Bus B to the fault. In order to avoid tripping out Bus B forthis fault, the load side relays protecting Transformer I must coordinate with the loadside relays protecting Transformer II. If the load side relays on Transformer I andTransformer II are conventional overcurrent elements, it is clearly impossible for theload side relays on Transformer I and Transformer II to coordinate properly with eachother for both faults internal to Transformer I and Transformer II.
By employing directional overcurrent relays as the load side relays protecting Trans-formers I and II, coordination between the relays is no longer necessary since the loadside relays on Transformer I will only detect faults internal to Transformer I and theload side relays on Transformer II will only detect fault internal to Transformer II. It isimportant to note that the directional overcurrent relays must be polarized toward thefaults they are to protect, which does not necessarily correspond to the direction ofnormal power flow.
For the same reasons discussed above, directional overcurrent protection is also usedto protect transmission lines and distribution feeders operated in a loop configurationor supplied from two directions, as shown in Figure 2-18.
Phase and ground directional overcurrent protection may be turned on and off inde-pendently. Directional overcurrent relay elements are available with a wide array of di-rectional curves and characteristic time-current curves.
There are four definite time (Instantaneous elements with optional timers) and two in-verse time directional overcurrent elements in the device. The definite time (Instanta-neous) directional elements include two phase elements and two ground elements.The definite time directional phase elements are designated 67-2 and 67-1 whereasthe definite time directional ground elements are designated 67N-2 and 67N-1. Theinverse time directional elements include a directional phase element designated as67-TOC and a directional ground element designated as 67N-TOC.

Depending on the setting of parameter 0613A 50N/51N/67N w.the ground currentstage can operate either with measured values Ignd or with the values 3I0 calculatedfrom the three phase currents. Devices featuring a sensitive ground current input,however, generally use the calculated quantity 3I0.
All directional overcurrent elements, inverse and definite time, enabled in the devicemay be blocked via an external signal to the binary inputs of the device or via auto-matic reclosure (cyclically). Removal of the external signal to the binary input will re-enable these elements. Also, a feature described as Manual Close Mode can be con-figured to improve fault clearing times associated with Switch-on-to-Fault Conditions.

Under this situation, the time delay may be defeated for one of the three directionalovercurrent phase elements and one of the three directional overcurrent ground ele-ments via an impulse from the external control switch, thus resulting in high speed trip-ping. This impulse is prolonged by a period of 300 ms. The directional phase andground elements utilized for high speed tripping in this situation are selected at ad-dresses 1513 and 1613 respectively.
Pickup and delay settings may be quickly adjusted to system requirements via dynam-ic setting swapping (see Section 2.4).
Tripping by the 67-1, 67-TOC, 67N-1, and 67N-TOC elements may be blocked for in-rush conditions by utilizing the inrush restraint feature.

Directional Overcurrent Protection (67, 67N)
Pickup and Trip-ping
Each phase and ground current is separately compared with the pickup values of the67-TOC and 67N-TOC relay elements. When the currents in the 67-TOC and 67N-TOC relay elements exceed the corresponding pickup value by a factor of 1.1, the el-ement picks up and a message is reported, if the current is in the set direction. If theinrush restraint feature is being utilized, then the message reported is dependent onwhether or not an inrush condition exists. Pickup of a 67-TOC or 67N-TOC relay ele-ment is based on the rms value of the fundamental harmonic. When the 67-TOC and67N-TOC elements pickup, the time delay of the trip signal is calculated using an in-tegrated measurement process. The calculated time delay is dependent on the actualfault current flowing and the selected time-current characteristic curve. Once the timedelay elapses, a trip signal is issued.
If the inrush restraint feature is enabled, and an inrush condition exist, no trippingtakes place, but a message is recorded and displayed indicating when the overcurrentelement time delay elapses. The r.m.s. values of the fundamental waves are used forthe pickup.
The characteristic curves of the 67-TOC and 67N-TOC relay elements may be select-ed independently of each other. In addition, pickup, time multipliers, and time dials forthe 67-TOC and 67N-TOC elements may be individually set.
Dropout For IEC orANSI Curves
Dropout of an element using an IEC or ANSI curve occurs when the current decreasesto about 95 % of the pickup value if instantaneous reset is selected, or 90 % of thepickup value if disk emulation is selected. When instantaneous reset is selected, resetof the element occurs without delay. When disk emulation is selected, reset occursjust as it would for an electromechanical relay utilizing an induction disk.
For disk emulation, the reset process begins after fault current is interrupted. Resetcorresponds to the unwinding of an induction disk. A subsequent pickup of the relayelement prior to full reset will result in a reduced tripping time delay. The reduced trip-ping time delay will be based on the degree to which the relay had reset when the sub-sequent pickup occurred. When the current in the relay element is between 90 % and95 % of the pickup value following dropout, neither disk movement in the tripping orreset direction is simulated.
Disk emulation offers advantages when the inverse time, directional overcurrent relayelements must be coordinated with conventional electromechanical overcurrent relayslocated toward the source.
User SpecifiedCurves
When user specified curves are utilized, the time-current characteristic curve may bedefined point by point. Up to 20 pairs of values (current, time) may be entered. Therelay element then approximates the curve using linear interpolation.
When utilizing user specified time-current curves, the reset curve may be user speci-fied as well. This is advantageous when the inverse time, directional overcurrent pro-tection must be coordinated with conventional electromechanical overcurrent relayslocated toward the source. If user specified reset curves are not utilized, the relay el-ement drops out when current decreases to about 95% of the relay element’s pickupvalue, and immediate reset takes place.
Figure 2-21 shows by way of example the logic diagram for the overcurrent stage 67-TOC of the inverse directional time-overcurrent protection of the phase currents.

2.3.1.3 Determination of Direction
Determination of fault direction is performed independently for each phase elementand for the ground element.
Methods ofDeterminingDirection
For the a-phase directional elements, direction is determined by comparing Ia with Vbcat the relay location. For the b-phase and c-phase directional elements, direction is de-termined by comparing Ib with Vca and Ic with Vab at the relay location. For phase-to-ground, phase-to-phase, and double phase-to-ground faults, sufficient voltage magni-tude is available at the relay location to determine direction for all possible fault loca-tions. For three-phase faults, stored voltage values are used to determine direction un-less sufficient voltage magnitudes exists at the relay location. The stored voltage val-ues correspond to the voltage magnitudes and angles during the last two cycles where

sufficient voltage magnitude was available to determine direction. When sufficient volt-age magnitude is not available to determine direction, direction is locked until sufficientvoltage returns. When closing into a three-phase fault, if voltage magnitude is not suf-ficient to determine direction and no stored voltage values exist in the buffer, the relayelement will trip without regard to fault direction. In all other cases the voltage magni-tude will be sufficient for determining the direction.
For the directional ground fault elements, direction is determined by comparing V0 withI0. The current I0 may be obtained from a current transformer connected in the residualpath or may be calculated by the device from the three phase currents. The voltageV0 may be calculated by the device from the three phase-to-ground voltages or thevoltage 3V0 may be obtained by connecting the secondary windings of the voltagetransformers in a broken delta configuration. If the magnitude of V0 or 3V0 is not suf-ficient to determine direction, then the directional ground elements will not initiate a tripsignal. If the current I0 cannot be determined because only two current transformersare utilized or the current transformers are connected in an open delta configuration,then the directional ground elements will not be able to function.
Phase-to-ground faults are detected by the directional ground element, and may bedetected by the directional phase element associated with the faulted phase if themagnitude of the fault current is sufficient. Phase-to-phase faults are detected by thetwo directional phase elements associated with the faulted phases. Double phase-to-ground faults are detected by the directional ground element, and may be detected bythe directional phase elements associated with the faulted phases if the magnitude ofthe fault current flowing in the phase conductors is sufficient. Three-phase faults, ofcourse, are detected by all directional phase elements, but not by the directionalground elements. As was stated earlier, in order for any ground fault to be detected bya directional ground element, current transformers and voltage transformers must beconnected so as to supply sufficient magnitudes of zero sequence currents and volt-age.
For a phase-to-ground fault, the voltage supplied to the directional phase element pro-tecting the faulted phase is 90° out of phase with the phase-to-ground voltage existingon the faulted phase at the relay location (see Figure 2-22). The device compensatesfor this phase difference by adding 90° when the phase sequence is “abc” and sub-tracting 90° when the phase sequence is “acb.” The resulting voltage is called the po-larizing voltage. For phase-to-phase faults, the angles of the polarizing voltages asso-ciated with the directional phase elements which protect the faulted phases can varybased upon the location of the fault with respect to the device. The relationship be-tween the polarizing voltage angle and the phase current angle for a phase-to-phasefault is identical to the relationship between the polarizing voltage angle and the phasecurrent angle for a phase-to-ground fault only when the fault location and relay loca-tion are identical.

of the directional phase element polarizing voltage to the directional phase elementcurrent. Line ‘a’ represents the directional limit line, and when the protective relayviews an impedance which lies on the same of the directional limit line as the shadedarea, the fault is assumed to be in the forward direction.
For a phase-to-phase fault, the actual directional limit line will deviate from the theo-retical when the fault location is different than the relay location because the polarizingvoltage angle varies with fault location (see Figure 2-22b). For a b-to-c fault, the direc-tional limit for the b-phase directional element rotates clockwise as the location be-tween the relay and fault increases (dotted line ‘b’ in Figure 2-23). Likewise, the direc-tional limit for the c-phase directional element rotates counterclockwise as the locationbetween the relay and fault increases (dotted line c in Figure 2-23). Rotation of the di-rectional limit in this manner is irrelevant in practice, since the impedance viewed bythe relay either lies in the first or third quadrant of the R-X diagram.

2.3.1.4 Reverse Interlocking for Looped Lines
ApplicationExample
The reverse interlocking principle may be applied to a group of transmission lines anddistribution feeders which operate in a looped configuration or which are supplied fromtwo directions. High speed protection is possible using reverse interlocking by havingthe directional overcurrent elements block high speed non-directional overcurrent el-ements as shown in Figure 2-24. This scheme is feasible when the lengths of the linesare not too great and when pilot wires are available for signal transfer.
For each line, a separate data transfer path is required to facilitate signal transmissionin each direction. These transfer paths carry the blocking signals to the opposite endof the lines. In addition, at each line terminal, two directional overcurrent elementsmust be employed, one polarized to operate for faults in the forward direction (towardthe line) and one polarized to operate for faults in the reverse direction. If a line is en-ergized, but open at one end, an interruption of the transfer path is noted and reportedwith a delay.

During a line fault, the directional overcurrent element that detects faults in the forward(line) direction will block the high speed operation of the non-directional overcurrentelements in the reverse direction. The non-directional relays that are blocked are gen-erally located at the same substation. In addition, a message is generated regardingthe fault direction and transmitted to the relays located in the reverse direction. Duringa fault in the reverse direction, the directional overcurrent element that detects faultsin the reverse direction will block the high-speed operation of the non-directional over-current element at the opposite end of the line. The relay at the opposite end of theline is generally located at a different substation, thus blocking is accomplished via thepilot wires. In addition, a message is generated regarding the fault direction and trans-mitted to the relay located at the opposite end of the line.

Directional Overcurrent Protection (67, 67N)
2.3.2 Programming Directional Overcurrent Settings
In contrast to the main functions of non-directional phase and ground overcurrent pro-tection, all other protective functions are disabled upon device delivery. The accom-panying addresses appear in the overview of setting groups only when the functionsare configured as present (Section 2.1.1). The functions may be enabled by selectinga time characteristic(i.e. Definite, ANSI, or User-Defined) during configuration.
When selecting the directional time-overcurrent protection in DIGSI® 4 a dialog boxappears with several tabs for setting individual parameters. Depending on the func-tional scope specified during configuration of the protective functions in addresses0115 67/67-TOC and 0116 67N/67N-TOC the number of tabs can vary.
2.3.2.1 General
Phase CurrentStages
If address 0115 67/67-TOC was set to Definite Time, then only the settings forthe definite-time elements are available. Selecting TOC IEC or TOC ANSI the inversecharacteristics will be available in addition. The superimposed directional stages 67-2and 67-1 apply in all these cases.
At address 1501 FCT 67/67-TOC, directional phase overcurrent protection may beswitched ON or OFF.
Ground CurrentStage
At address 1601 FCT 67N/67N-TOC, directional ground time-overcurrent protectionmay be switched ON or OFF independent of the directional phase time-overcurrent pro-tection.
Depending on the parameter 0613A 50N/51N/67N w., the device can either oper-ate using measured values Ignd or the quantities 3I0 calculated from the three phasecurrents. Devices featuring a sensitive ground current input, however, generally usethe calculated value 3I0.
Pickup values, time delays, and characteristic curves for ground protection are setseparately from the pickup values, time delays and characteristic curves associatedwith directional phase protection. Because of this, relay coordination for ground faultsis independent of relay coordination for phase faults, and more sensitive settings canoften be applied to directional ground protection.
Manual Close Mode(Phase, Ground)
When a circuit breaker is closed into a faulted line, a high speed trip by the circuitbreaker is often desired. The manual closing feature is designed to remove the delayfrom one of the directional overcurrent elements when a circuit breaker is manuallyclosed into a fault. The time delay may be bypassed via an impulse from the externalcontrol switch, thus resulting in high speed tripping. This impulse is prolonged by a pe-riod of 300 ms. Address 1513A MANUALCLOSEMODE can be set such that the delay isdefeated for the 67-2 element, the 67-1 element, the 67-TOC element, or none of theelements. Accordingly, address 1613A MANUALCLOSEMODE is considered for theground path address. Defeating the delay on just one of the three elements (phaseand ground) allows control over what level of fault current is required to initiate highspeed tripping of a circuit breaker that is closed into a fault.
External ControlSwitch
If the manual closing signal is not from a 7SJ62/63/64, that is, neither via the built-inoperator interface nor via a series interface, but, rather, directly from a control ac-
757SJ62/63/64 ManualC53000-G1140-C147-1
Functions
knowledgment switch, this signal must be passed to a 7SJ62/63/64 binary input, andconfigured accordingly so that the element selected for high speed tripping will be ef-fective.
Internal controlfunction
The manual closing information must be routed via CFC (interlocking task-level) usingthe CMD_Information block, if the internal control function is used (see Figure 2-26).
Figure 2-26 Example for manual close feature using the internal control function
Direction Limit Lineand DirectionalOrientation
At address 1515A Normal Load, the directional limit line may be set asInductive(135×), Resistive (90×), or Capacitive(45×) (see Figure 2-27).As a rule, the option Inductive(135×) is used since power system elements areinductive by nature.
The directional orientation may be established at address 1516 67N Direction. Di-rectional overcurrent protection normally operates in the direction of the facility to beprotected (line, transformer, etc.). If the device is properly connected in accordancewith one of the circuit diagrams in Appendix A3, this is the Forward direction.
Figure 2-27 Definition of the Directional Limit Line (addresses 1515A and 1516)
If the voltage used to determine fault direction drops below the minimum value, record-ed voltage values are available from a buffer based on the last two cycles of sufficientvoltage. If recorded voltage is not available due to closing in on a fault, tripping will takeplace without directional determination.

If the voltage used to determine fault direction drops below the minimum value, record-ed voltage values are available from a buffer based on the last two cycles of sufficientvoltage. If recorded voltage is not available due to closing in on a fault, a tripping willnot occur.
Inrush Restraint When applying the protection device to transformers where high inrush currents areto be expected, 7SJ62/63/64 can make use of an inrush restraint function for the di-rectional overcurrent stages 50-1 PICKUP, 51 PICKUP, 50N-1 PICKUP and 51N PICKUP together with the non-directional overcurrent stages. The inrush restraint op-tion is enabled or disabled at 2201 INRUSH REST. (at the parameters for the non-directional time overcurrent protection) Subsection 2.2.2.6 shows the characteristicvalues of the inrush restraint feature.
2.3.2.2 Definite-Time, Directional Overcurrent Protection (67-2, 67-1)
67-2 Relay Element The pickup and delay of the 67-2 relay element are set at addresses 1502 67-2 PICKUP and 1503 67-2 DELAY respectively. In setting the pickup and delay of the67-2 element, the same considerations apply as did for the determining the pickup anddelay of the 50-2 element in Subsection 2.2.2.1.
The delay set at address 1503 is in addition to the 67-2 pickup time. The delay of the67-2 element may be set to ∞. The 67-2 element will then pickup and generate a mes-sage, but will never trip. If the 67-2 element is not required at all, then the pickup valueshould be set to ∞ thus preventing pickup, trip, and the generation of a message.
67-1 Relay Element The pickup value of the 67-1 relay element (set at address 1504 67-1 PICKUP)should be set above the maximum anticipated load current. Pickup due to overloadshould never occur since the 50-1 relay element is designed only for fault protection.For this reason, a setting equal to 120 % of the expected peak load is recommendedfor line protection, and a setting equal to 140 % of the expected peak load is recom-mended for transformers and motors.
If the 7SJ62/63/64 relay is used to protect transformers or motors with large inrush cur-rents, the inrush restraint feature may be used to prevent a false trip of the 67-1 relayelement. The configuration data for the inrush restraint feature is programmed at ad-dress block 22 (see Subsection 2.9.2).
The delay of the 67-1 element is set at address 1505 67-1 DELAY and should bebased on system coordination requirements. The delay for directional elements is usu-ally set shorter than the delay for non-directional elements since the non-directionalelements overlap the directional elements as backup protection.

Functions
For parallel transformers supplied from a single source (see Figure 2-17), the delay ofthe directional elements located on the load side of the transformers may be set tozero if desired.
The delay set at address 1505 is in addition to the 67-1 pickup time. The delay of the67-1 element may be set to ∞. The 67-1 element will then pickup and generate a mes-sage, but will never trip. If the 67-1 element is not required at all, then the pickup valueshould be set to ∞ thus preventing pickup, trip, and the generation of a message.
Interaction withAutomaticReclosingEquipment
When reclosing occurs, it is desirable to have high speed protection against temporaryfaults. If the fault still exists after the first reclose, the 67-2 elements can be blockedand the 67-1 elements will provide time delay tripping. At address 1514A 67 active,it can be specified whether or not the 67-2 elements should be supervised by the sta-tus of an internal or external automatic reclosing device. If address 1514A is set toWith 79 Active, the 67-2 elements will not operate unless automatic reclosing isnot blocked. If address 1514A is set to Always, the 67-2 elements will always oper-ate.
Die integrierte Wiedereinschaltautomatik im 7SJ62/63/64 bietet außerdem die Mög-lichkeit, für jede der gerichteten Überstromzeitschutzstufen getrennt festzulegen, obunverzögert, unbeeinflusst von der AWE mit der eingestellten Zeit ausgelöst oder blo-ckiert werden soll (siehe Abschnitt 2.13.1.3).
2.3.2.3 Inverse-Time Directional Overcurrent Protection (67-TOC)
67-TOC RelayElement With IEC orANSI Curves
Having set TOC IEC or TOC ANSI in address 0115 67/67-TOC when configuringthe protective functions (Subsection 2.1.1), the parameters for the inverse character-istics will also be available.
Pickup of the 67-TOC relay element will occur for currents greater than or equal to110% of the 67-TOC element’s pickup value, and may or may not occur for currentsbetween 100% and 110% of the 67-TOC element’s pickup value. Dropout of the 67-TOC relay element occurs when the current decreases to 95 % of the 67-TOC ele-ment’s pickup value.
The pickup of the 67-TOC element is set at address 1507 67/67-TOC. As is the casefor the 67-1 relay element, the pickup value of the 67-TOC relay element should beset above the maximum anticipated load current. Pickup due to overload should neveroccur since the 67-TOC relay element is designed only for fault protection. For thisreason, a setting equal to 120 % of the expected peak load is recommended for lineprotection, and a setting equal to 140 % of the expected peak load is recommendedfor transformers and motors.
The 67-TOC element time multiplication factor for an IEC curve is set at address 1508 67 TIME DIAL and in address 1509 51c TIME DIAL for an ANSI curve and shouldbe based on system coordination requirements.
The time multiplication factor may be set to ∞. The 67-TOC element will then pickupand generate a message, but will never trip. If the 67-TOC element is not required atall, address 0115 should be set to Definite Time during protective function con-figuration (see Section 2.1.1).
If Disk Emulation is selected at address 1510 67-TOC Drop-out, then resetoccurs according to the reset curve as described in Subsection 2.2.1.2.

Directional Overcurrent Protection (67, 67N)
If address 0115 67/67-TOC was set to TOC IEC, you can specify the desired IECcurve (Normal Inverse, Very Inverse, Extremely Inv. or Long Inverse)in address 1511 51N IEC CURVE. Having selected TOC ANSI in address 0115 67/67-TOC, you can specify the desired ANSI curve (Very Inverse, Inverse, Short Inverse, Long Inverse, Moderately Inv., Extremely Inv. oder Definite Inv.) in address 1512 51N ANSI CURVE.
User SpecifiedCurves
If address 0115 67/67-TOC was set to User Defined PU or User def. Resetduring configuration of the user-specified curve option, a maximum of 20 value pairs(current and time) may be entered at address 1530 67 to represent the time-currentcharacteristic curve associated with the 67-TOC element. This option allows point-by-point entry of any desired curve.
If address 0115 was set to User def. Reset during configuration of the user-spec-ified curve option, additional value pairs (current and reset time) may be entered at ad-dress 1531 MofPU Res T/Tp to represent the reset curve associated with the 67-TOC element.
Current and time values are entered as multiples of the address 1507 and 1508 set-tings. Therefore, it is recommended that addresses 1507 and 1508 be initially set to1.00 to simplify the calculation of these ratios. Once the curve is entered, the settingsat addresses 1507 and 1508 may be modified if necessary.
Upon delivery of the device, all time values are set at ∞, preventing pickup of the de-vice from initiating a trip signal.
When entering a user-specified curve, the following must be observed:
− The value pairs should be entered in increasing sequence. As few as 10 pairs ofnumbers may be entered at the user’s option. Each unused pair must then bemarked as unused by entering “∞“for the time and current values. It is important toview the curve to ensure that it is clear and constant.
− The current values entered should be those from Table 2-8, along with the matchingtimes. Other values for MofPU are changed to the nearest adjacent value althoughthis is not indicated.
− Current flows which are less than the smallest current value entered will not lead toa reduction of the reset time below the time associated with the smallest current val-

2.3.2.4 Programming Settings for Directional Overcurrent Ground Protection
General The functions associated with time-overcurrent protection were established duringconfiguration of protective functions (Section 2.1.1) at address 0116 67N/67N-TOC.If address 0116 was set to Definite Time, then only the settings for the definite-time elements are available. Select 67N/67N-TOC = TOC IEC or = TOC ANSI to haveavailable inverse characteristics in addition. The superimposed directional high-setstage 67N-2 is available in all these cases.
At address 1601 FCT 67N/67N-TOC, directional ground time-overcurrent protectionmay be switched ON or OFF independent of the directional phase time-overcurrent pro-tection.
Pickup values, time delays, and characteristic curves for ground protection are setseparately from the pickup values, time delays and characteristic curves associatedwith directional phase protection. Because of this, relay coordination for ground faultsis independent of relay coordination for phase faults, and more sensitive settings canoften be applied to directional ground protection.
67N-2 RelayElement
The pickup and delay of the 67N-2 relay element are set at addresses 1602 67N-2 PICKUP and 1603 67N-2 DELAY respectively. The same considerations apply forthese settings as did for 67-2 settings discussed earlier.
The delay set at address 1603 is in addition to the 67N-2 pickup time. The delay ofthe 67N-2 element may be set to ∞. The 67N-2 element will then pickup and generatea message, but will never trip. If the 67N-2 element is not required at all, then the pick-up value should be set to ∞, thus preventing pickup, trip, and the generation of a mes-sage.
67N-1 RelayElement
The pickup value of the 67N-1 relay element (set at address 1604 67N-1 PICKUP)should be set below the minimum anticipated ground fault current in the relay zone ofprotection.
If the 7SJ62/63/64 relay is used to protect transformers or motors with large inrush cur-rents, the inrush restraint feature may be used to prevent a false trip of the 67N-1 relayelement. The configuration data for the inrush restraint feature is programmed at ad-dress block 22 (at the parameters for the non-directional time overcurrent protection,see Subsection 2.2.2.6).
The delay of the 67N-1 element is set at address 1605 67N-1 DELAY and should bebased on system coordination requirements.
The delay set at address 1605 is in addition to the 67N-1 pickup time. The delay ofthe 67N-1 element may be set to ∞. The 67N-1 element will then pickup and generatea message, but will never trip. If the 67N-1 element is not required at all, then the pick-up value 67N-1 PICKUP should be set to ∞ thus preventing pickup, trip, and the gen-eration of a message.

2.3.2.5 Inverse-Time Directional Overcurrent Protection (67N-TOC)
67N-TOC with IECor ANSI Curves
Having set TOC IEC in address 0116 67N/67N-TOC when configuring the protec-tive functions (Section 2.1.1), the parameters for the inverse characteristics will alsobe available. Specify in address 1611 67N-TOC IEC the desired IEC curve (Normal Inverse, Very Inverse, Extremely Inv. or Long Inverse). If you have setTOC ANSI at address 0116 67N/67N-TOC, you can specify the desired ANSI curve(Very Inverse, Inverse, Short Inverse, Long Inverse, Moderately Inv., Extremely Inv. or Definite Inv.) in address 1612 67N-TOC ANSI.
Pickup of the 67N-TOC relay element will occur for currents greater than or equal to110% of the 67N-TOC element’s pickup value, and may or may not occur for currentsbetween 100% and 110% of the 67N-TOC element’s pickup value. Dropout of the 51Nrelay element occurs when the current decreases to 95% of the 67N-TOC element’spickup value. If Disk Emulation is selected at address 1610 67N-TOC RESET,then reset occurs according to the reset curve as described in Subsection 2.3.1.2.
The pickup value of the 67N-TOC element is set at address 1607 67N-TOC PICKUP.The corresponding time dial for an IEC curve is set at address 1608 67N-TOC T-DIAL and for an ANSI curve at address 1609 67 TIME DIAL and should be basedon system coordination requirements. As is the case for the 67N-1 relay element, thepickup value of the 67N-TOC relay element should be set below the minimum antici-pated ground fault current in the relay zone of protection.
The time multiplication factor may also be set to ∞. The 67N-TOC element will thenpickup and generate a message, but will never trip. If the 67N-TOC element is not re-quired at all, address 0116 should be set to Definite Time during protective func-tion configuration (see Section 2.1.1).
User SpecifiedCurves
If address 0116 67N/67N-TOCwas set to User Defined PU or User def. Resetduring configuration of the user-specified curve option, a maximum of 20 value pairs(current and time) may be entered at address 1630 M.of PU TD to represent thetime-current characteristic curve associated with the 67N-TOC element. This optionallows point-by-point entry of any desired curve.
If address 0116 was set to User def. Reset during configuration of the user-spec-ified curve option, additional value pairs (current and reset time) may be entered at ad-dress 1631 I/IEp Rf T/TEp to represent the reset curve associated with the 67N-TOC element.
Current and time values are entered as multiples of the address 1607 and 1608 set-tings. Therefore, it is recommended that addresses 1607 67N-TOC PICKUP and1608 67N-TOC T-DIAL be initially set to 1.00 to simplify the calculation of theseratios. Once the curve is entered, the settings at addresses 1607 and 1608 may bemodified if necessary.
Upon delivery of the device, all time values are set at ∞, preventing pickup of the de-vice from initiating a trip signal.
When entering user specified curve data, the same instructions apply as in Subsection2.3.2.3 for the phase elements.

Dynamic Cold Load Pick-Up Function (50c, 50Nc, 51Nc, 67c, 67Nc)
2.4 Dynamic Cold Load Pick-Up Function (50c, 50Nc, 51Nc, 67c, 67Nc)
General With the dynamic cold load pickup feature, it is possible to dynamically increase thepickup values of the directional and non-directional overcurrent relay elements whendynamic cold load pickup conditions are anticipated (i.e. after a long period of zerovoltage). By allowing pickup settings to increase dynamically, it is not necessary to in-corporate dynamic cold load capability in the normal pickup settings, and directionaland non-directional overcurrent protection may be set more sensitive.
As a further option the pickup thresholds can be modified in dependence of an auto-matic reclosure function that is ready or not ready.
It is possible to change pickup thresholds and delay times.
2.4.1 Description of Dynamic Cold Load Pick-Up Function
Effect When using the dynamic cold load pick-up function, there are two primary methodsused by the device to determine if the protected equipment is de-energized:
• Via a binary input, an auxiliary contact in the circuit breaker can be used to deter-mine if the circuit breaker is open or closed. If the circuit breaker is open, the equip-ment will be considered de-energized. If this method is chosen, address 1702 Start Condition should be set to Breaker Contact.
• The current flow monitoring threshold (Subsection ) may be used to determine if theequipment is de-energized. If this method is chosen, address 1702 should be setto No Current.
If the device determines the protected equipment is de-energized via one of the meth-ods above, a time CB Open Time is started and after its expiration the increasedthresholds take effect.
In addition, switching between parameters can be tripped by two further signals:
• By signal “79M Auto Reclosing ready“ of the internal automatic reclosure function(address 1702 Start Condition = 79 ready). Thus the protection thresholdsand the tripping times can be changed if automatic reclosure is ready for tripping(see also Section 2.13).
• Irrespective of the setting of parameter 1702 Start Condition the release forthe cold load pickup can always be granted via the binary input “>ACTIVATE CLP“.
Figure 2-31 shows the logic diagram for dynamic cold load pick-up function.
When the auxiliary contact or current criterion detects that the system is de-energized,i.e. the circuit breaker is open, the CB open time (CB Open Time) starts. As soon asthe time period expired, the greater thresholds become enabled.
When the protected equipment is re-energized (i.e. the device receives input via a bi-nary input that the circuit breaker is closed or the current flowing through the circuit
Note:
Dynamic Cold Load Pickup is in addition to the 4 setting groups (A to D), which areconfigured separately.

breaker increases above the current flow monitoring threshold set at address 0212 BkrClosed I MIN), a second time delay referred to as the Active Time is initiated.Once the Active Time elapses, the pickup values of the relay elements return totheir normal settings. The Active Time is set at address 1704 and controls how longdynamic cold load pick-up settings remain in place once the equipment is re-ener-gized. Upon re-energizing of the equipment, if the measured current values are belowthe normal pickup settings, an alternative time delay referred to as the Stop Time isalso initiated. As in the case with the Active Time, once the Stop Time elapses,the pickup values of relay elements change from the dynamic cold load pickup valuesto their normal settings. The Stop Time is set at address 1705 and controls how longdynamic cold load pick-up settings remain in place given that measured currents arebelow the normal pickup settings. This Stop Time is typically set very short since theactual measurement of currents indicates dynamic cold load conditions will not inad-vertently pickup the relay elements. To defeat the Stop Time from switching the relayelement pickup settings back to normal, it may be set to ∞ or blocked via a binary input.
If a relay element picks up while the dynamic settings are enabled, elapse of the Ac-tive Time or Stop Time will not restore the normal pickup settings until drop outof the relay element occurs based on the dynamic settings.
When the dynamic setting values have taken effect via the binary input “>ACTIVATE CLP“ or the signal “79M Auto Reclosing ready” and this cause drops out, the “normal”settings are restored immediately, even if a pick up is to follow.
If the dynamic cold load pick-up function is blocked via a binary input, all triggered tim-ers will be immediately reset and all normal settings will be restored. If blocking occursduring an on-going fault with dynamic cold load pick-up functions enabled, the timersof all directional and non-directional overcurrent relay elements will be stopped, andthen restarted based on their normal duration.
During power up of the protective relay with an open circuit breaker, the time delay setat address 1703 CB Open Time is started, and is processed using the normal set-tings. Therefore, when the circuit breaker is closed, the normal settings are effective.
Figure 2-30 shows a timing diagram, Figure 2-31 describes the logic for cold load pick-up function.

Depending on the start conditions for the cold load pickup function address 1702Start Condition is set to either No Current, Breaker Contact or to 79 ready. Naturally, the option Breaker Contact can only be selected if the devicereceives an information on the position of the circuit breaker via at least one binary in-put. The option 79 ready modifies dynamically the pickup thresholds of the direction-al and non-directional time overcurrent protection when the automatic reclosing fea-ture is ready. For controlling the cold load pickup the automatic reclosing function pro-vides the internal signal “79M Auto Reclosing ready”. It is always active when auto re-closure is available, activated, unblocked and ready for a further cycle (see also sidetitle “Controlling Directional/Non-Directional Overcurrent Protection Stages via ColdLoad Pickup“ in Subsection 2.13.2).
Time Delays There are no specific procedures on how to set the time delays at addresses 1703 CB Open Time, 1704 Active Time and 1705 Stop Time. These time delays mustbe based on the specific loading characteristics of the equipment being protected, andshould be selected to allow the brief overloads associated with dynamic cold load con-ditions.

2.5 Voltage Protection (27, 59)
General Voltage protection has the function to protect electrical equipment against undervolt-age and overvoltage. Both operational states are unfavorable as undervoltage maycause for example stability problems and overvoltage may lead to insulation problems.
2.5.1 Description of Voltage Protection
2.5.1.1 Measurement Principle
VT Connection The voltages supplied to the device may correspond to the three phase–to–groundvoltages, or two phase-to-phase voltages and the displacement voltage, depending onhow the voltage transformers are connected. 7SJ64 provides the option to detectthree phase-ground voltages and the ground voltage in addition. The connectionmode has been specified during the configuration in address 0213 VT Connection.
Overvoltage protection requires the phase–phase voltages and if necessary they arecalculated from the phase-earth voltages. In case of phase-phase connection two volt-ages are measured and the third is calculated.
Undervoltage protection relies on the positive-sequence component of the phase-to-phase voltages.
The option between phase–ground and phase–phase voltage allows voltage asym-metries (e.g. caused by a ground fault) to be taken into account (phase–ground) or leftunconsidered (phase–phase).
CurrentSupervision
The primary voltage transformers are arranged, depending on the system, either onthe supply side or the load side of the associated circuit breaker. These different ar-rangements lead to different behavior of the voltage protection function when a faultoccurs. When a circuit breaker is opened, full voltage remains on the supply side whilethe load side voltage becomes zero. Opening the circuit breaker when voltage trans-formers are located on the load side of the circuit breaker causes the undervoltageprotection to remain picked up. Therefore, the flow of current through the circuit break-er can be used as an additional criteria for pickup of undervoltage protection. Whencurrent supervision is active, for undervoltage pickup to occur, the current through thecircuit breaker must exceed a minimum current level which corresponds to the currentflow monitoring setting at address 0212 BkrClosed I MIN. The circuit breaker istripped, when the current decreases below the current flow monitoring setting, and un-dervoltage protection will drop out.
Note:
If current supervision is turned off under address 5120A CURRENT SUPERV., the un-dervoltage function will pick up without 3 phase voltage applied. The device cannot beprogrammed if in pickup. Apply 3 phase voltage or block the voltage protection to con-tinue with programming! Moreover you have the option of setting a flag via device op-eration for blocking the voltage protection. This initiates the reset of the pickup anddevice parameterization can be resumed.

Voltage Protection (27, 59)
Preparation of Mea-sured Data
Using a Fourier Analysis, the fundamental harmonic component of the three phase-to-phase voltages are filtered out and passed along for further processing. For undervolt-age protection, the positive sequence components of the phase-to-phase voltages areevaluated, while for overvoltage protection, the largest of the three phase-to-phasevoltages is evaluated.
2.5.1.2 Overvoltage Protection (59)
Application The overvoltage protection has the task of preventing insulation failure by protectingagainst abnormally high voltage levels.
Abnormally high voltages often occur in low loaded, long distance transmission lines,in islanded systems when generator voltage regulation fails, or after full load shutdownof a generator from the system.
Function Overvoltage protection consists of two definite time elements designated 59-2 and 59-1. The pickup and delay settings of each element are individually adjustable. The fun-damental harmonic of the largest phase–to–phase voltages is provided to the over-voltage protection elements. When an adjustable setting is exceeded, the 59 elementpickups, and after an adjustable time delay elapses, initiates a trip signal. The 59 ele-ment is a definite time element in that the time delay is not a function of the voltagemagnitude.
Figure 2-32 shows the logic diagram of the overvoltage protection element.

Application Undervoltage protection detects and reports abnormally low voltage conditions, someof which could be related to system stability problems (voltage collapse, etc.). Under-voltage protection is generally used for load shedding and loss of phase purposes.
Function Undervoltage protection consists of two definite time elements designated 27-2 and27-1. The pickup and delay settings of each element are individually adjustable. Forundervoltage protection, the positive sequence components of the phase-to-phasevoltages are evaluated. The 27 element is a definite time element in that the time delayis not a function of the voltage magnitude.
With the 27-1 element, the ratio of drop out voltage to pickup voltage (27-1 DOUT RATIO) is settable as well.
The undervoltage protection will not be blocked when the permissible frequency rangeof fN = ± 10 % (45 Hz to 55 Hz at fN = 50 Hz) is left. This ensures that the protectivefunction is preserved even when it is applied as motor protection in context with decel-erating motors. However, the r.m.s. value of the positive-sequence component of thevoltages is evaluated too small for strongly deviating frequencies so that the devicetends to exhibit unwanted operation. If application cases are anticipated who leave thefrequency range of fN ± 10 %, the current criterion will not return a correct result. Thecurrent criterion must be deactivated.
Figure 2-33 shows a typical voltage profile during a fault for source side connection ofthe voltage transformers. Because full voltage is present after the circuit breaker isopened, current supervision is unnecessary.
After the voltage has decreased below the pickup setting of the 27-1 element, the 27-1 time delay is initiated, after which, the 27-1 element is used to block reclosing. Aslong as the voltage remains below the drop out setting, reclosing is blocked. When thevoltage increases above the drop out level, the 27-1 element drops out and allows re-closing of the circuit breaker.

Figure 2-34 shows a fault profile for a load side connection of the voltage transformers.When the circuit breaker is open, the voltage disappears and the 27-1 element picksup and times out. When the current drops below the current flow monitoring setting ataddress 0212 BkrClosed I MIN (i.e. the current criterion is no longer met) the 27-1 element will drop out even though the voltage remains below the pick-up setting ofthe 27-1 element.

Figure 2-34 Typical Fault Profile for Load Side Connection of the Voltage Transformers(with current supervision)
The instant after a circuit breaker is closed, the load side voltage begins to increaseand current begins to flow through the circuit breaker. To ensure that the 27-1 elementdoes not pickup, the element remains dropped out for a short period of time (about40ms) until both the current flowing through the circuit breaker and the load side volt-age stabilize. It is important to understand, however, that if a low voltage condition ex-ists on the load after the circuit breaker is closed (i.e. a fault exists on the load side ofthe circuit breaker), pickup of the 27-1 element will be delayed by 40 ms.

2.5.2 Programming Settings
Voltage protection is only in effect and accessible if address 0150 27/59 is set toEnabled during configuration of protective functions. If the voltage protection functionis not needed, address 0150 should be set to Disabled.
All setting values are based on phase-to-phase voltages. The setting ranges dependon the type of voltage transformer connection utilized (specified at address 0213 VT Connection). For voltage transformers connected in a grounded-wye configuration,higher setting values may be used because the voltage inputs are subjected only tophase-to-ground voltage levels.
2.5.2.1 Voltage Protection – General
Undervoltage protection can be turned ON, OFF, or set to Alarm Only at address5101 FCT 27. When undervoltage protection is turned ON, tripping by the undervolt-age elements is allowed.
Overvoltage protection can be turned ON, OFF, or set to Alarm Only at address 5001FCT 59. When address 5001 is set to ON, tripping by the overvoltage element is al-lowed.
2.5.2.2 Undervoltage Protection
Pickup Values There are not clear cut procedures for setting the pickup values of the undervoltagerelay elements. However, because the undervoltage protection function is primarily in-tended to protect induction machines from voltage dips and to prevent stability prob-lems, the pickup values will usually be between 60% and 85% of the nominal voltage.The time delay settings should be selected to prevent voltage dips from causing un-stable conditions, however, the time delay should be long enough to avoid tripping dueto momentary voltage dips.
Undervoltage protection includes two definite time elements. The pickup value of the27-2 element is set at either address 5110 or 5111 27-2 PICKUP (depending on thevoltage transformer connection) while the time delay is set at address 5112 27-2 DELAY. The pickup of the 27-2 element is typically set low while the time delay is setshort, thus this element is used for fast protection against severe undervoltage condi-tions. The pickup value of the 27-1 element is set at either address 5102 or 5103 27-1 PICKUP (depending on the voltage transformer connection) while the time delay isset at address 5106 27-1 DELAY. The pickup of the 27-1 element is typically set highwhile the time delay is set long, thus this element is used for slower protection againstless severe undervoltage conditions. Setting the 27-2 and 27-1 relay elements in thismatter allows the undervoltage protection function to closely follow the stability behav-ior of the system.
Dropout Setting While the drop out setting on the 27-2 element is set permanently to 105% of the pick-up setting, the drop out setting on the 27-1 element can be set at address 5105A 27-1 DOUT RATIO as a multiple of the pickup setting. However, the following limitationsare to be observed:

(Address 5105A) x (Address 5103) cannot exceed 130 V when address 0213 = Vab, Vbc, VGnd.
(Address 5105A) x (Address 5102) cannot exceed 225 V when address 0213 = Van, Vbn, Vcn.
CurrentSupervision
The 27-2 and 27-1 elements can be supervised by the current flow monitoring setting(BkrClosed I MIN) entered at address 0212. If address 5120A CURRENT SUPERV. isswitched on, then the 27-2 and 27-1 elements will not pickup until the current flowingthrough the circuit breaker exceeds the setting entered at address 0212 (typically setvery sensitive). In other words the sustained pickup of the 27-2 and 27-1 elements isdependent on the circuit breaker being closed, as determined by “BkrClosed I MIN.” A benefit of current supervision is that the feature prevents an immediate gen-eral-pickup of the device that would otherwise be caused by the 27 elements when thedevice is powered-up without voltage being present.
The 50 element “BkrClosed I MIN” is used in other protective functions as well,including breaker failure protection, overload protection, and start inhibit for motors.
2.5.2.3 Overvoltage Protection
Pickup Values The overvoltage protection relies on phase-phase voltages. Accordingly, the pickupvalues, too, must always be considered phase–to–phase voltages. The overvoltageprotection is designed in two stages. Thus, the lower threshold (address 5002 or5003, 59-1 PICKUP can be assigned a long delay time (depending on whetherphase-ground or phase-phase voltages are connected) (address 5004, 59-1 DELAY)and the upper threshold (address 5005 or 5006, 59-2 PICKUP) can be assigned ashort delay time (address 5007, 59-2 DELAY). There are not clear cut procedures onhow to set the pickup value of the overvoltage element. However, because the over-voltage function is primarily intended to prevent insulation damage, the pickup of theovervoltage element 59-1 PICKUP should be set between 110 % and 115 % of nom-inal voltage, and the pickup of the overvoltage element 59-2 PICKUP should be setabout 130 % of nominal voltage. Depending on the type of voltage transformer con-nection utilized, the pickup value may be entered at address 5002 and 5005 (usedwhen voltage transformers are connected in a grounded-wye configuration) or 5003 and 5006 (used when voltage transformers are not connected in a grounded-wyeconfiguration). The time delays of the overvoltage elements are entered at addresses
Note:
If a setting has a value of greater than 130 V or 225 V results for the drop out setting,the drop out setting will be automatically limited. No error message occurs.
Note: When switching off the CURRENT SUPERV. setting under Address 5120A, thedevice immediately picks up if voltage is not present and the undervoltage protectionis switched on. The device cannot be programmed if in pickup. Apply 3 phase voltageto continue with programming or block voltage protection! The blocking can be initiat-ed via device operation in DIGSI® 4 and via communication from the control center bymeans of a tagging command. This causes the reset of the pickup and parameteriza-tion can be resumed.

2.6 Negative Sequence Protection (46)
General Negative sequence protection detects unbalanced loads on the system. In addition, itmay be used to detect interruptions, faults, and polarity problems with current trans-formers. It is particularly useful in detecting phase-to-ground, phase-to-phase, anddouble phase-to-ground faults with magnitudes lower than the maximum load current.
Use with Motors The application of negative sequence protection to motors has a special significance.The negative sequence currents associated with unbalanced loads create counter-ro-tating fields in three-phase induction motors, which act on the rotor at double frequen-cy. Eddy currents are induced at the rotor surface, and local overheating of the rotorbegins to take place. In addition, the threat of thermal overload exists when the motoris supplied by unbalanced system voltages. Because the motor represents a small im-pedance to negative sequence voltages, small voltage imbalances can lead to largenegative sequence currents.
2.6.1 Description of Negative Sequence Protection
2.6.1.1 Determination of Unbalanced Load
The negative sequence protection feature of the 7SJ62/63/64 relay uses filtering todissect the phase currents into their symmetrical components. The negative-phasesequence system is evaluated by these components, i.e. the inverse current I2. If thelargest of the three phase currents is at least 10% of the nominal device current, andall phase currents are less than four (4) times the nominal device current, then thenegative sequence current is fed into three time-overcurrent relay elements, two ofwhich are definite time (see Figure 2-36) and one of which contains an inverse timecharacteristic (see Figure 2-37).
Refer to phase rotation via binary input section 2.1.3 and 2.18.
2.6.1.2 Definite Time Elements (46-1, 46-2)
The two definite time elements are designated 46-2 and 46-1. Each of the two definitetime elements will generate a message and initiate a time delay when picked up. Onceeither time delay elapses, a trip signal is initiated. Figure 2-36 illustrates the definitetime characteristic when the 46-1 element is set with a more sensitive pickup valuewhile the 46-2 element is set with a shorter tripping delay.
104 7SJ62/63/64 ManualC53000-G1140-C147-1
Negative Sequence Protection (46)
Figure 2-36 Definite Time Characteristic for Negative Sequence Protection
2.6.1.3 Inverse Time Element (46-TOC)
The inverse time element is designated 46-TOC and can operate with IEC or ANSIcharacteristic tripping curves depending on the model ordered. The curves and asso-ciated formulas are given in the Technical Specifications (Figures 4-7 to 4-9 in Section4.8). When programming the inverse time curve, the definite time elements are avail-able (see Subsection 2.6.1.2).
Pickup andTripping
When the negative sequence current exceeds the pickup setting of the 46-TOC ele-ment by 110%, the element picks up, generates a message, and initiates time delayedtripping based on the selected characteristic curve. Once the corresponding time in-terval on the curve elapses, a tripping signal is initiated. The characteristic curve is il-lustrated in Figure 2-37.
Drop Out for IECCurves
When IEC curves are used, the 46-TOC element drops out when the negative se-quence current decreases to 95 % of the pickup setting. The time delay resets imme-diately in anticipation of another pickup.
Drop Out for ANSICurves
When ANSI curves are used, the 46-TOC element may drop out immediately whenthe negative sequence current decreases to 95 % of the pickup setting, or disk emu-lation may be used to simulate the unwinding of an electromechanical induction disc.
If disk emulation is selected, the drop out begins when the current decreases to 90 %of the pickup value, and reset proceeds in accordance with the selected reset curve.When the negative sequence current is between 90 % and 95 % of the pickup setting,neither forward nor reverse movement of the disk is simulated. When the negative se-quence current falls below 5 % of the pickup value, disk emulation is terminated andimmediate reset takes place. Figure 2-37 illustrates the overall tripping characteristic.

Negative Sequence Protection (46)
Disk emulation offers advantages when the negative sequence protection must be co-ordinated with conventional source side relays.
Logic Figure 2-38 shows the logic diagram for negative sequence protection. The protectionmay be blocked via a binary input. This resets pick-ups and time steps and clearsmeasured values.
When the negative sequence protection criteria are no longer satisfied (i.e. all phasecurrents drop below 10 % of the nominal relay current or at least one phase current isgreater than four (4) times the nominal device current, the tripping time delay is imme-diately reset.
2.6.2 Programming Settings
2.6.2.1 General
Negative sequence protection is configured at address 0140 46. If only the definitetime elements are desired, address 0140 should be set to Definite Time. If bothdefinite time and inverse time elements are to be used, address 0140 should be setto TOC IEC or TOC ANSI, and if negative sequence protection is not needed, address0140 should be set to Disabled.
Negative sequence protection is switched ON or OFF at address 4001 FCT 46.
The default pickup settings and delay settings of the negative sequence time-overcur-rent relay elements are generally sufficient for most applications. If the device is usedto protect a motor, and data is available from the manufacturer regarding the allowablelong-term load imbalance and the allowable load imbalance per unit of time, this datashould be used as the basis for selecting the pickup and delay settings. In this situa-tion, it is important to ensure that the values given by the manufacturer represent theprimary values for the motor. For example, if the long-term allowable thermal inversecurrent (with respect to the nominal motor current) is given, this value is used to cal-culate the settings for the negative sequence time-overcurrent element. For this situ-ation:
2.6.2.2 Definite Time Elements
The pickup and delay settings associated with the 46-1 element are set at addresses4002 46-1 PICKUP and 4003 46-1 DELAY respectively while the pickup and delaysettings for the 46-2 element are set at address 4004 46-2 PICKUP and 4005 46-2 DELAY respectively. Typically the 46-1 element is set with a lower pickup value and

higher time delay than the 46-2 element. This allows the 46-1 element to act as analarm while the 46-2 element will initiate fast tripping for severe imbalances.
If the 46-2 element is used for fast tripping against severe imbalances, the pickup val-ue should be set at 60 % of the nominal phase current. This will ensure pickup for thecomplete loss of one phase. On the other hand, because the loss of a phase could beinterpreted as a phase-to-phase fault, the time delay of this element should be coor-dinated with fault protection relays. The magnitude of the negative sequence currentwith respect to the phase current when one phase is out of service is given as follows:
Examples:
This ensures
When protecting a feeder, negative sequence protection may serve to identify lowmagnitude unsymmetrical faults below the pickup values of the directional and non-directional overcurrent elements. To detect load magnitude faults, the pickup value ofthe negative sequence time-overcurrent elements must be set below the following:
− a phase-to-phase fault (I) results in the following negative sequence current:
− a phase-to-ground fault (I) corresponds to the following negative sequence current:
To prevent false operations for fault in other zones of protection, the time delay shouldbe coordinated with other fault protection relays in the system.
For a transformer, negative sequence protection may be used as sensitive protectionfor low magnitude phase-to-ground and phase-to-phase faults. In particular, this ap-plication is well suited for delta-wye transformers where low side phase-to-groundfaults do not generate high side zero sequence currents.
The relationship between negative sequence currents and total fault current for phase-to-phase faults and phase-to-ground faults are valid for the transformer as long as theturns ratio is taken into consideration.

Negative Sequence Protection (46)
Consider a transformer with the following data:
The following faults may be detected at the lower-voltage side:
If the pickup setting (PU) of the device on the high side is set to 0.1 A, then a phase-to-ground fault current of
I = (1/0.33) * CTR * PU * VHS / VLS =
3 * 100 * 0.1 A * 110 kV / 20 kV = 165 A
and a phase-to-phase fault current of
I = (1/0.58) * CTR * PU * VHS / VLS =
1.732 * 100 * 0.1 A * 110 kV / 20 kV = 95 A
can be detected at the low side. These faults correspond to 36 % and 20 % of the basetransformer rating respectively. It is important to note that load current is not taken intoaccount in this simplified example.
As it cannot be recognized reliably on which side the thus detected fault is located, thedelay time must be coordinated with other relays in the system to prevent false oper-ation for faults in other zones of protection.
2.6.2.3 Inverse Time Element 46-TOC
IEC Curves If the 46-TOC element is employed, a characteristic tripping curve should be selectedto coordinate with the thermal overload curve representing the protected equipment(e.g. induction motor, etc.). The curve should be selected at address 4006 46 IEC CURVE. The characteristic tripping curves, and the formulas on which they are based,are given in the Technical Specifications, Section 4.8.
The 46-TOC element picks up when the negative sequence input current exceeds110% of the pickup settings and drops out when he negative sequence current de-creases to 95 % of the pickup setting. The pickup settings is entered at address 400846-TOC PICKUP.
The associated time multiplier is entered at address 4010 46-TOC TIMEDIAL.
The time multiplier may also be set to ∞ thus allowing the element to pickup and gen-erate a message, but never to trip.

2.7 Motor Protection (Motor Starting Protection, 48 and Start Inhibit forMotors, 66/68)
2.7.1 Description of Motor Starting Protection
General When the 7SJ62/63/64 relay is used to protect a motor, the starting time monitoringfeature supplements the overload protection described in Section 2.9 by protecting themotor against the potential damage that might result from frequent starting or extend-ed starting durations. In particular, rotor-critical high-voltage motors can quickly beheated above their thermal limits when multiple starting attempts occur in a short pe-riod of time. If the durations of these starting attempts are lengthened by excessivevoltage surges during motor starting, by excessive load moments, or by blocked rotorconditions, a tripping signal will be initiated by the device.
Motor starting protection consists of two time-overcurrent tripping characteristics initi-ated by the motor starting recognition setting entered at address 1107 I MOTOR START. One characteristic is definite time while the other one is inverse time. Whenthe motor phase currents exceed the setting entered at address 1107, time delayedtripping will be initiated. To gain a better understanding of how to set the motor startingrecognition setting at address 1107, refer to side title “Recognition of Running Condi-tion” in Subsections 2.1.6 and 2.9.2.2.
Inverse Time-Over-current Character-istic
The inverse time-overcurrent characteristic is designed to operate only when the rotoris not blocked. When the phase currents exceed the motor starting recognition settingentered at address 1107, time delayed tripping via the inverse time characteristic isinitiated. The inverse time characteristic allows motor starting protection to adjust forthose situations where high starting voltages result in decreased starting currents. Thetripping time is calculated based on the following formula:
tTRIP
IA
I-----
2tAmax⋅= where I> IMOT START
where tTRIP – Actual tripping time for flowing current I
tA max – Tripping time for nominal start-up current IA (set at address 4103)
I – Current actually flowing (measurement value)
IA – Nominal starting current of the motor (set at address 4102)
IMOT START – Pickup value for recognition of motor starting (set at address 1107)

Motor Protection (Motor Starting Protection, 48 and Start Inhibit for Motors, 66/68)
Figure 2-39 Inverse Time Characteristic Tripping Curve for Motor Starting Current
Therefore, if the starting current I actually measured is smaller (or larger) than thenominal starting current IA entered at address 4102 STARTUP CURRENT, the actualtripping time ttrip is lengthened (or shortened) accordingly. See Figure 2-39.
Definite TimeOvercurrent Trip-ping Characteristic(Blocked RotorTime)
During motor starting, the definite time characteristic is designed to initiate a trip if themotor starting time exceeds the maximum allowable blocked rotor time. The devicecan detect a blocked rotor condition via a binary input („>Rotor locked“) from anexternal rpm-counter. If the current in any of the phases exceeds the motor startingrecognition setting entered at address 1107, and if a blocked rotor conditions is de-tected via a binary input, a motor starting condition is assumed, and time delayed trip-ping via the definite time characteristic will be initiated (based on the maximum allow-able blocked rotor time).
It is important to note that message generation does not occur unless a trip is initiated.Furthermore, when a blocked rotor condition is detected via a binary input, and thedefinite time characteristic times out, immediate tripping will take place regardless ofwhether the blocked rotor condition was detected before or after the definite time char-acteristic timed out.
Logic Motor starting protection may be switched on or off at address 4101 48. In addition,motor starting protection may be blocked via a binary input, at which time pickup mes-sages and time delays will be reset. Figure 2-40 illustrates the logic for motor startingprotection. A pick up does not create a fault record. Fault recording is not started untila trip command has been issued. When the function drops out the starting time, theblocked rotor time and the annunciations are reset and the fault recording is terminat-ed.

2.7.2 Description of Start Inhibit for Motor
General The rotor temperature of a motor generally remains well below its maximum allowabletemperature during normal operation and even during severe loading conditions. How-ever, during motor starting, the rotor can heat up quickly. If multiple starting attemptsare made in a short duration of time, the rotor could suffer thermal damage. Therefore,the 7SJ62/63/64 motor start blocking feature is available. A motor start blocking signalis initiated when the relay projects rotor temperature will exceed the maximum allow-able rotor temperature, and blocking continues until the calculated rotor temperaturedecreases below the reset level. To block starting, the blocking signal must be con-nected to a binary output whose contact is inserted in the motor starting circuit.
DeterminingExcessive RotorTemperature
Because the rotor current cannot be measured directly, the stator current must beused to generate a thermal profile of the rotor. The excessive rotor temperature is cal-culated using the highest of the three phase currents. The thermal limit values for therotor winding are based on manufacturer’s data regarding the nominal starting current,maximum permissible starting time, and the number of starts permitted from cold andwarm conditions. From this data, the device performs the necessary calculations toestablish the thermal rotor profile and issues a blocking signal until the thermal rotorprofile decreases below the restarting limit.

Motor Protection (Motor Starting Protection, 48 and Start Inhibit for Motors, 66/68)
Figure 2-41 Temperature Curve at the Rotor and the Thermal Profile during Repeated Start-ing Attempt
Although the heat distribution at the rotor brushes can range widely during motor start-ing, the different maximum temperatures in the rotor do not necessarily affect motorstart blocking (see Figure 2-41). It is much more important to establish a thermal pro-file, after a complete motor start, that is appropriate for the protection of the motor’sthermal condition. Figure 2-41 shows, as an example, the heating processes duringrepeated motor starts (three starts from cold operating condition), as well as the ther-mal reproduction by the protective relay.
Restarting Limit If the rotor temperature has exceeded the restarting limit, the motor cannot be restart-ed. When the rotor temperature goes below the restarting limit, that is, when exactlyone start becomes possible without exceeding the excessive rotor temperature limit,the blocking signal is terminated.
Therefore the restarting temperature related to trip temperature is expressed as:
The restarting limit ΘRestart/ΘTrip is displayed as operational measured value in the“thermal measured values”. The value changes only if the number of admissible coldrestarts ncold alters and is indicated in % and without decimal positions.

Functions
Restarting Times When giving the maximum allowable cold and warm starting attempts, the motor man-ufacturer assumes the motor is not restarted immediately after motor shutdown. Thisassumption is made because the distribution of heat in the rotor, is very different im-mediately after motor shutdown. Only after a certain heat equilibrium time has passedcan a new starting attempt be made.
Equilibrium Time The device can allow for the equilibrium time via a programmable time interval enteredat address 4304 T Equal. Each time the motor is shutdown, the timer starts, and thecalculated thermal profile of the rotor does not change until this timer elapses. Oncethe time interval entered at address 4304 elapses, the device assumes equilibriumhas taken place in the rotor, and the thermal profile begins to update. A time of zerocan be entered at address 4304 at the option of the user. Then the thermal model withthe corresponding time constant (rotor time constant ∗ extension factor) cools down.During the equilibrium time the motor cannot be restarted. As soon as the temperaturesinks below the restarting threshold, the next restarting attempt can be made.
Minimum InhibitTime
Regardless of thermal profiles, some motor manufacturers require a minimum inhibittime after the maximum number of permissible starting attempts has been exceeded.
The total duration of the inhibit signal depends on which of the times T MIN INIHBIT orTRESTART is longer.
Total Time Trecloseuntil release of re-close blocking
The entire time that must elapse before motor starting can resume is equal to the equi-librium time entered at address 4304 and the amount of time, calculated via the ther-mal model, that it takes for the rotor temperature to decrease to the reset temperaturelevel. If the calculated excessive temperature of the rotor is above the restarting limitwhen the motor is shut down, the minimum inhibit time will be started together with theequilibrium time. Thus the total inhibit time Treclose can become equal to the minimuminhibit time if it is longer than the sum of the two first mentioned times:
The operational measured value Treclose (visible in the “thermal measured values”) isthe remaining time until the next restart is permissible. When the rotor overtempera-ture is below the restarting limit and thus the next restarting attempt is permitted, theoperational measured value for the waiting time Treclose has reached zero.
Extension of TimeConstants
In order to properly account for the reduced heat exchange when a self-ventilated mo-tor is stopped, the cooling time constants can be increased relative to the time con-stants for a running machine with the factor Kt at STOP (address 4308). A stoppedmotor is defined by current below an adjustable current flow monitoring thresholdBkrClosed I MIN, assuming that the motor idle current is greater than this thresh-old. The pickup threshold BkrClosed I MIN also effects the thermal overload pro-tection function (see Section 2.9).
While the motor is running, the heating of the thermal profile is modelled with the timeconstant τL calculated from the motor ratings and the cool-down calculated with the
Treclose TEqual TRestart+= for TMIN INHIBIT < TEqual+ TRESTART
Treclose TMIN INHIBIT= for TMIN INHIBIT ≥ TEqual + TRESTART, if thecalculated excessive temperature > re-starting limit
116 7SJ62/63/64 ManualC53000-G1140-C147-1
Motor Protection (Motor Starting Protection, 48 and Start Inhibit for Motors, 66/68)
time constant τL ⋅ Kt at RUNNING (address 4309). In this way, the protection catersto the requirements in case of a slow cool-down (slow temperature equilibrium).
For the calculation of the restarting time TRESTART the following holds:
Behavior in Case ofPower SupplyFailure
Depending on the setting of parameter 0235A ATEX100 in Power System Data 1 (seeSubsection 2.1.3) the value of the thermal replica will be reset to zero if power supplyvoltage fails (ATEX100 = NO) or if it is buffered cyclically in a “non-transient” bufferstorage (ATEX100 = YES) that is preserved in the event of a supply voltage failure. Inthe latter case, the thermal replica uses the buffered values for its calculation andadapts it to the operational conditions. The first option is set by default. For further in-formation please refer to the “Device Description on the Protection of Explosion-Pro-tected Motors of Protection Type Increased-Safety e” (Order No. C53000-B1174-C157).
Emergency Start If, under emergency conditions, motor starting in excess of the maximum allowable ro-tor temperature must take place, the motor start blocking signal can be terminated viaa binary input (“>66 emer.start“), thus allowing a new starting attempt.The thermalrotor profile continues to function, however, the maximum allowable rotor temperaturewill be exceeded. No motor shutdown will be initiated by motor start blocking, but thecalculated excessive temperature of the rotor can be observed for risk assessment.
Blocking/Logic The restarting limit does not feature a pickup annunciation and neither a fault record-ing is initiated. If the motor start blocking function is blocked via binary input “>BLOCK 66” or switched off, the thermal profile of the excessive rotor temperature and the equi-librium time are reset, and any existing motor start blocking signal is terminated.
Via a binary input (“>66 RM th.repl.”) the thermal replica can be reset indepen-dently. This may be useful for testing and commissioning, and after a power supplyvoltage failure.

2.7.3.2 Motor Starting Protection (48)
Under normal conditions the values of the startup current are entered at address 4102STARTUP CURRENT and those of the startup time at address 4103 STARTUP TIME.At all times this enables timely tripping if the value I2t calculated in the protection de-vice is exceeded.
If the startup time is longer than the permissible blocked rotor time, an external rpm-counter can initiate the definite-time tripping characteristic via binary input(“>Rotor locked“). A locked rotor leads to a loss of ventilation and therefore to areduced thermal load capacity of the machine. For this reason the motor starting timesupervision is to issue a tripping command before reaching the thermal tripping char-acteristic valid for normal operation.
A current above the current threshold is interpreted as motor startup. Consequently,this value must be selected such that under all load and voltage conditions during mo-tor startup the actual startup current safely exceeds the setting, but stays below thesetting in case of permissible, momentary overload.
Example: Motor with the following data:
The setting for Address 4102 STARTUP CURRENT is calculated as follows:
For reduced voltage, the start-up current is also reduced almost linearly. At 80% nom-inal voltage, the start-up current in this example is reduced to
0.8 * I.STARTUP = 2.5 A.
The setting at address 1107 I MOTOR START must lie above the maximum load cur-rent and below the minimum start-up current. If no other influencing factors arepresent (peak loads), the value set at address 1107 may be a median value:
Nominal Voltage V N = 6600 V

For ratios deviating from nominal conditions, the motor tripping time changes:,
At 80 % of nominal voltage (which corresponds to 80 % of nominal starting current),the tripping time is:
After the definite time characteristic times out (4104 LOCK ROTOR TIME), the blockedrotor binary input becomes effective and initiates a tripping signal. If the time delay as-sociated with the definite time characteristic is set such that at normal startup the bi-nary input “>Rotor locked” (06805) is blocked during the delay time LOCK ROTOR TIME, a shorter delay time of the tripping command can be realized than for unblockedstartup.
2.7.3.3 Start Inhibit for Motors (66, 86)
Many of the variables needed to calculate the rotor temperature are supplied by themotor manufacturer. Among these variables are the starting current, the nominal mo-tor current, the maximum allowable starting time T START MAX (address 4303), thenumber of allowable starts from cold conditions (ncold), and the number of allowablestarts from warm conditions (nwarm).
The starting current is entered at address 4302 IStart/IMOTnom, expressed as amultiple of nominal motor current. In contrast, the nominal motor current is entered asa secondary value, directly in amperes, at address 4305 I MOTOR NOMINAL. Thenumber of warm starts allowed is entered at address 4306 MAX.WARM STARTS andthe difference between the number of allowable cold and warm starts is entered at ad-dress 4307 #COLD-#WARM.
For motors without separate ventilation, the reduced cooling at motor stop can be ac-counted for by entering the factor Kt at STOP at address 4308. As soon as the cur-rent no longer exceeds the current flow monitoring setting entered at address 0212 BkrClosed I MIN, the time constant is increased by the kτ factor.
If no difference between the time constants is to be used (e.g. externally-ventilatedmotors), then the factor Kt at STOP should be set to 1.
Cool-down with running motor is influenced by the extension factor 4309 Kt at RUN-NING. This factor considers that motor running under load and a stopped motor do notcool down at the same speed. It becomes effective as soon as the current exceedsthe value set at address 0212 BkrClosed I MIN. With Kt at RUNNING = 1 theheating and the cooling time constant are the same at operating conditions(I > BkrClosed I MIN).

For the rotor temperature equilibrium time, (address 4304) a setting time of approx. T Equal = 1 min has proven to be a good value. The value for the minimum inhibit time4310 T MIN. INHIBIT depends on the requirements made by the motor manufac-turer, or by the system conditions. It must in any case be higher than 4304 T Equal.In this example, a value has been chosen that reflects the thermal profile (T MIN. INHIBIT = 6.0 min).
The motor manufacturer's, or system requirements determine also the extension fac-tor for the time constant during cool-down, especially with the motor stopped. Whereno other specifications are made, the following settings are recommended:Kt at STOP = 5 und Kt at RUNNING = 2.
For a proper functioning, it is also important that the CT values and the threshold cur-rent for distinction between stopped and running motor (address 0212 BkrClosed I MIN, recommended setting ≈ 0.1 ⋅ I/IN Motor) have been set correctly. An overviewof the parameters and their default settings is given in the tables at the end of this sec-tion and in the Appendix.
TemperatureBehavior duringChangingOperating States
For a better understanding of the above considerations several possible operatingstates in two different operating areas will be discussed in the following paragraph.The examples use the settings indicated above. 3 cold and 2 warm startup attemptshave resulted in a restart limit of 66.7 %:
A. Below the thermal restarting limit
1.A normal startup brings the machine into a temperature range below the thermalrestarting limit and the machine is stopped. The stop launches the equilibriumtime 4304 T Equal and generates the message “66 TRIP“. The equilibriumtime expires and the message “66 TRIP“ is cleared. During the time T Equalthe thermal model remains “frozen“ (see Figure 2-43, to the left).

2.A normal startup brings the machine into a temperature range below the thermalrestarting limit, the machine is stopped and is started by an emergency startupwithout expiration of the equilibrium time. The equilibrium time is shed and thethermal model is released and “66 TRIP“ is reported cleared (see Figure 2-43,to the right).

1.A startup brings the machine from load operation into a temperature range farabove the thermal restarting limit and the machine is stopped. The minimum in-hibit time and the equilibrium time are started and “66 TRIP“ is reported. Thetemperature cool-down below the restarting limit takes longer than 4310 T MIN. INHIBIT and 4304 T Equal, so that the time passing until the temper-ature falls below the temperature limit is the decisive factor for clearing the mes-sage “66 TRIP“. The thermal model remains “frozen” while the minimum inhibittime expires (see Figure 2-44, to the left).

2.8 Frequency Protection (81 O/U)
2.8.1 Description of Frequency Protection
General The frequency protection function detects abnormally high and low frequencies in thesystem. If the frequency lies outside the allowable range, appropriate actions are ini-tiated, such as load shedding or separating a generator from the system.
A decrease in system frequency occurs when the system experiences an increase inthe real power demand, or when a malfunction occurs with a generator governor orautomatic generation control (AGC) system.
An increase in system frequency occurs when large blocks of load are removed fromthe system, or again when a malfunction occurs with a generator governor or AGCsystem.
The frequency is detected from the phase–to–phase voltages Va-b applying at the de-vice. If the amplitude of this voltage is too small, one of the other phase–to–phase volt-ages is used instead.
Through the use of filters and repeated measurements, the frequency evaluation isfree from harmonic influences and very accurate.
Underfrequencyand OverfrequencyProtection
Frequency protection consists of four frequency elements. Any given frequency ele-ment can be set to pickup for either overfrequency or underfrequency conditions. Eachelement can be independently set, and utilized to perform different functions within thesystem. The setting decides on the purpose of the individual frequency stage. For thef4 frequency stage, the user can specify independently of the parameterized limit val-ue if this stage shall function as decrease or increase stage. For this reason, it can alsobe used for special applications, if, for example, the user desires a signalization incase of a frequency overrange being below the nominal frequency.
Operating Ranges The frequency can be determined as long as at least one of the phase–to–phase volt-ages is present and of sufficient magnitude. If the measurement voltage drops belowa settable value Vmin, then frequency protection is blocked. For elements used in anunderfrequency protection mode, as soon as the frequency of the measured voltagedecreases below the setting, the element picks up and remain picked up until the sys-tem frequency increases above the setting. For elements used in an overfrequencyprotection mode, as soon as the frequency of the measured voltage increases abovethe setting, the element picks up and remains picked up until the frequency decreasesbelow the setting.
Logic Each frequency element has an associated settable time delay. When a frequency el-ement picks up and the time delay elapses, a trip signal is generated. When a frequen-cy elements drops out, the control signal (tripping or alarm signal) is immediately ter-minated, but not before the minimum command duration 0210A TMin TRIP CMDhas elapsed. Each of the four frequency elements can be blocked individually by bi-nary inputs. Figure 2-45 shows the logic diagram for the frequency protection function.The 81 element is a definite time element in that the time delay is not a function of thefrequency magnitude.

If underfrequency protection is used for load shedding purpose, then the frequencysettings relative to other feeder relays are generally based on the priority of the cus-tomers served by the protective relay. The actual settings of the underfrequency ele-ments must be based on network stability requirements.
For 60 Hz systems, the frequency pickup settings for elements one (1) through four(4) are entered at addresses 5404, 5407, 5410, and 5413 respectively.
For 50 Hz systems, the frequency pickup settings for elements one (1) through four(4) are entered at addresses 5403, 5406, 5409, and 5412 respectively.
Delays The time delays (Definite Time) entered at addresses 5405, 5408, 5411, and 5414,allow the device to prioritize or order corrective actions based on the degree to whichthe actual system frequency departs (upward or downward) from the nominal systemfrequency.

2.9 Thermal Overload Protection (49)
2.9.1 Description of Thermal Overload Protection
General The thermal overload protection feature of the 7SJ62/63/64 is designed to preventoverloads from damaging the protected equipment.
The device is capable of projecting excessive operating temperatures for the protect-ed equipment in accordance with a single-body thermal model, based on the followingdifferential equation:
If the ambient or coolant temperature is not measured, a constant value of ϑu = 40°Cis assumed so that Θu = 0.
The thermal overload protection feature models a heat image of the equipment beingprotected. Both the previous history of an overload and the heat loss to the environ-ment are taken into account.
Thermal overload protection calculates the operating temperature of the protectedequipment as a percent of the maximum allowable operating temperature. When thecalculated operating temperature reaches a settable percentage (49 Q ALARM) of themaximum allowable operating temperature, a warning message is issued to allow timefor the load reduction measures to take place. When the calculated operating temper-ature reaches 100 % of the maximum allowable operating temperature, a trip signal isinitiated to de-energize the overloaded equipment. Initiation of a trip signal is based onthe phase with the highest calculated temperature.
The maximum thermally-permissible continuous current Imax is described as a multipleof the nominal current IN:

Thermal Overload Protection (49)
Imax = k × IN
For thermal overload protection to calculate operating temperature as a percent ofmaximum allowable operating temperature, it is necessary to enter the k factor setting(49 K-FACTOR), the time constant setting τth (TIME CONSTANT) and the warningtemperature level Θ (49 Q ALARM) in percent of the trip temperature ΘTRIP.
Thermal overload protection also features a current warning element (I ALARM) in ad-dition to the temperature warning stage. The current warning element may report anoverload current prematurely, even if the calculated operating temperature has not yetattained the warning or tripping levels.
CoolantTemperature(AmbientTemperature)
The device can account for external temperatures. Depending on the type of applica-tion, this may be a coolant or ambient temperature. The temperature can be measuredvia a temperature detection unit (RTD-box). For this purpose, the required tempera-ture detector is connected to detector input 1 of the first RTD-box. If incorrect temper-ature values are measured or there are disturbances between the RTD-box and thedevice, an alarm will be issued and the standard temperature of ϑu = 40° C is used forcalculation with the ambient temperature detection simply being ignored.
For the detection of coolant temperature, the maximum permissible current Imax is in-fluenced by the difference between the coolant and the standard temperature of40° C. If the ambient or coolant temperature is low, the protected object can becharged higher than it is when the temperature is high.
Extension of TimeConstants
When using the device to protect motors, the varying thermal behaviors associatedwith cycling the motor on and off may be correctly evaluated. Under a cycling condi-tion, a motor without external cooling losses heat more slowly, and a longer thermaltime constant must be used. For a motor that is cycled on and off, the 7SJ62/63/64increases the time constant τth by a programmable factor (kτ factor). The motor is con-sidered off the motor currents drop below a programmable minimum current setting(BkrClosed I MIN, refer to “Current Flow Monitoring” in Subsection 2.1.3). For ex-ternally-cooled motors, cables, and transformers, the Kt-FACTOR = 1.
Blocking The thermal overload protection feature may be reset via a binary input(“>RES 49 Image”). The current-induced overtermperature value is reset to zero.The same is accomplished via the binary input (“>BLOCK 49 O/L”); in that case theoverload protection is blocked completely, including the current warning stage.
When motors must be started for emergency reasons, operating temperatures abovethe maximum permissible operating temperatures can be allowed by blocking the trip-ping signal via a binary input (“>EmergencyStart”). Since the calculated operatingtemperature may be higher than the maximum allowable operating temperature afterdrop out of the binary input has taken place, the thermal overload protection functionfeatures a programmable run-on time interval (T EMERGENCY) which is started whenthe binary input drops out. Tripping will be defeated until this time interval elapses. Ona final note, the binary input used for emergency starting affects only the tripping sig-nal. There is no effect on the fault condition protocol nor does the thermal image reset.
Behavior in Case ofPower SupplyFailure
Depending on the setting in address 0235A ATEX100 of Power System Data 1 (seeSubsection 2.1.3) the value of the thermal replica is either reset to zero (ATEX100 =NO) if the power supply voltage fails, or cyclically buffered in a non-volatile memory(ATEX100 = YES) until the power supply voltage is back again. In the latter case, the

thermal replica uses the stored value for calculation and matches it to the operatingconditions. The first option is the default setting.

2.9.2 Programming Settings
2.9.2.1 General
Thermal overload protection is only effective and accessible if address 0142 49 wasset to No ambient temp or With amb. temp. during configuration of protectivefunctions. If the thermal overload protection is not required, address 0142 49 shouldbe set to Disabled.
Transformers and cable are prone to damage by overloads which last for an extendedperiod of time. For this reason, fault protection elements such as the directional andnon-directional overcurrent elements should not be used to protect against overload.The short time delays associated with fault protection elements do not allow sufficienttime for the orderly curtailment of load by operating personnel. In addition, fault pro-tection elements set to trip for overload will not allow short-duration, non-damagingoverloads – a practice which is often required in real operating situations.
The 7SJ62/63/64 protective relay features an thermal overload protective function witha thermal tripping characteristic curve which may be adapted to the overload toleranceof the equipment being protected.
Thermal overload protection may be switched ON or OFF or Alarm Only at address4201 FCT 49. If switched ON, tripping is also possible.
2.9.2.2 Overload Settings
k–Factor The nominal device current is used as a basis for overload detection. The program-mable 49 K-FACTOR (set at address 4202) is calculated as the ratio of the thermally-permissible continuous current Imax to the nominal device current IN:
The thermally-permissible continuous current for the equipment being protected isknown from manufacturer’s specifications. The thermal overload function is normallynot applicable to aerial lines since the actual current capability of aerial lines is depen-dent on factors that are generally unknown (e.g. wind speed, ambient temperature,etc.). For cables, the permissible continuous current is dependent on the cross-sec-tion, insulating material, design, and the cable routing, among other things. It may betaken from pertinent tables, or is specified by the cable manufacturer. If no specifica-tions are available, a value of 1.1 times the nominal current rating is assumed.
When determining the nominal current rating of the protected equipment, it is impor-tant to relate this current to the nominal current rating of the device. For example, themaximum permissible continuous current for a motor and the nominal current rating ofthe motor are given in primary amperes.
For the k factor to be set based on the nominal device current, the following equationmust be used:

Thermal Overload Protection (49)
Example: Motor and current transformer with the following data:
Time Constant τth The thermal overload protection element tracks excessive temperature progression,employing a thermal differential equation whose solution is an exponential function.The TIME CONSTANT τth (set at address 4203) is used in the calculation to determinethe operating temperature. This is expressed as a maximum allowable operating tem-perature.
For cable protection, the heat-gain time constant τth is determined by cable specifica-tions and by the cable environment. If no time-constant specification is available, itmay be determined from the short-term load capability of the cable. The 1-sec current(i.e. the maximum current permissible for a one-second period of time), is often knownor available from tables. Then, the time constant may be calculated from the formula:
If the short-term load capability is given for an interval other than one sec, the corre-sponding short-term current is used in the above formula instead of the 1-sec current,and the result is multiplied times the given duration. For example, if the 0.5-secondcurrent rating is known,
It is important to note, however, that the longer the effective duration, the less accuratethe result.
Example:
Cable and current transformer with the following data:
Continuous permissible current Imax = 500 A @ 40 oC
Maximum current for 1 sec I1s = 45 * Imax = 22.5 kA
Current transformer 600 A / 1 A
The k factor and time constant are calculated as follows:
where Imax prim Maximum permissible continuous motor current in primaryamperes

The settings are: 49 K-FACTOR (Address 4202)= 0.83TIME CONSTANT = 33.7 min
Warning Tempera-ture Level
By setting the thermal warning level 49 Q ALARM at address 4204, a warning mes-sage can be issued prior to tripping, thus allowing time for load curtailment proceduresto be implemented. This warning level simultaneously represents the dropout level forthe tripping signal. In other words, the tripping signal is interrupted only when the cal-culated operating temperature falls below the warning level, thus allowing the protect-ed equipment to be placed back into service.
The thermal warning level is given in % of the tripping temperature level (maximumallowable operating temperature).
A current warning level is also available (I ALARM 4205). The setting at address 4205corresponds to secondary amperes, of course, and should be set equal to, or slightlyless than, permissible continuous current (k * INsec). The current warning level may beused in lieu of the thermal warning level by setting the thermal warning level to 100 %.
Extension of TimeConstants
The time constant programmed at address 4203 is valid for a running motor. For cy-cling motors without external cooling, the motor loses heat more slowly. For a cyclingmotor, the 7SJ62/63/64 takes the reduced heat loss into account by increasing thetime constant τth by a programmable factor (Kt-FACTOR, set at address 4207A).Motor stop is detected if the current falls below the threshold value BkrClosed I MIN of the current flow monitoring (see side title “Current Flow Monitoring” in Subsec-tion 2.1.3) assuming that the motor idle current is greater than this threshold. The pick-up threshold BkrClosed I MIN affects also the following protection functions: volt-age protection, breaker failure protection and restart inhibit for motors.
If no distinguishing of the time constants is necessary (e.g. externally-cooled motors,cables, transformers, etc.) the Kt-FACTOR is set at 1 (Default Setting value).
EmergencyStarting
The drop-out time T EMERGENCY to be entered at address 4208A must ensure thatafter an emergency startup and after dropout of the binary input “>EmergencyStart“the trip command is blocked until the thermal replica is below the dropout thresholdagain.
Ambient or CoolantTemperature
The indications specified up to now are sufficient for a temperature rise replica. Theambient or coolant temperature, however, can also be processed. This has to be com-municated to the device as digitalized measured value via the interface. During con-figuration the parameter 0142 49 must be set to With amb. temp.
If the ambient temperature detection is used, the user must be aware that the 49 K-FACTOR to be set refers to an ambient temperature of ϑu = 40 °C, i.e. it correspondsto the maximum permissible current at a temperature of 40 °C.

2.10 Monitoring Functions
The device is equipped with extensive monitoring capabilities - both for hardware andsoftware. In addition, the measured values are also constantly monitored for plausibil-ity, therefore, the current transformer and voltage transformer circuits are largely inte-grated into the monitoring. It is also possible to implement trip and closing circuit mon-itoring, using appropriate binary inputs as available.
2.10.1 Description of Measured Values Monitoring
2.10.1.1 Hardware Monitoring
The device is monitored from the measurement inputs to the binary outputs. Monitor-ing checks the hardware for malfunctions and disallowed conditions.
Auxiliary andReference Voltages
The processor voltage of 5 V DC is monitored, and if the voltage decreases below theminimum value, the device is removed from operation. When the normal voltage re-turns, the processor system is restarted.
Removal of or switching off the supply voltage removes the device from operation anda message is immediately generated by a dead contact. Brief voltage interruptions ofless than 50 ms do not disturb the readiness of the device (for nominal auxiliary volt-age ≥ 110 V DC).
The processor monitors the offset and reference voltage of the AD (analog-digital)converter. The protection is suspended if the voltages deviate outside an allowablerange, and lengthy deviations are reported.
Buffer Battery The buffer battery, which ensures the operation of the internal clock and the storageof counters and messages if the auxiliary voltage fails, is periodically checked forcharge status. If it is less than an allowed minimum voltage, then the “Fail Battery”message is issued.
The internal battery of 7SJ64 is switched off automatically by the clock module whenthe device has been disconnected from the auxiliary voltage for a period of 1 to 2 daysmeaning that clock management will be discontinued. The memory containing themessages and fault data is however preserved.
MemoryComponents
The working memory (RAM) is tested when the system is started up. If a malfunctionoccurs then, the starting sequence is interrupted and an LED blinks. During operation,the memory is checked using its checksum.
For the program memory, the cross sum is formed periodically and compared to thestored program cross sum.
For the settings memory, the cross sum is formed periodically and compared to thecross sum that is freshly generated each time the setting process takes place.
If a malfunction occurs, the processor system is restarted.
140 7SJ62/63/64 ManualC53000-G1140-C147-1
Monitoring Functions
Probing Probing and the synchronization between the internal buffer components are con-stantly monitored. If any deviations cannot be removed by renewed synchronization,then the processor system is restarted.
Measurement ValueCollection – Cur-rents
Up to four input currents are measured by the device. Three of the currents corre-spond to phase currents and the fourth current corresponds to the neutral or groundcurrent measured from a separate current transformer. If all four currents inputs areconnected, their digitized sum must be zero.
Faults in the current circuit are recognized if
IF = |ia+ib+ic+(kN⋅ig) | > S I THRESHOLD ⋅ IN + S I FACTOR ⋅ Imax
The factor kN takes into account a possible difference in the neutral current transform-er ratio (e.g. toroidal current transformer see addresses 0217, 0218, 0204 and0205):
S I THRESHOLD and S I FACTOR are programmable settings. The component S I FACTOR ⋅ Imax takes into account the allowable error of the input transformer, whichcan be especially large when high fault current levels are present (Figure 2-47). Thedropout ratio is about 97%.
This malfunction is reported as “Failure S I”.

2.10.1.2 Software Monitoring
Watchdog For continuous monitoring of the program sequences, a time monitor is provided in thehardware (hardware watchdog) that runs upon failure of the processor or an internalprogram, and causes a complete restart of the processor system.

Functions
An additional software watchdog ensures that malfunctions during the processing ofprograms are discovered. This also initiates a restart of the processor system.
To the extent such a malfunction is not cleared by the restart, an additional restart at-tempt is begun. After three unsuccessful restarts within a 30 second window of time,the device automatically removes itself from service and the red “Error” LED lights up.The readiness relay opens and indicates “device malfunction” with its normal contact.
2.10.1.3 Monitoring of External Current Transformer Circuits
Interruptions or short circuits in the secondary circuits of the current transformers orvoltage transformers, as well as faults in the connections (important for start-up!), aredetected and reported by the device. The measured quantities are periodicallychecked in the background for this purpose, as long as no system fault is present.
Current Symmetry During normal system operation (i.e. the absence of a short-circuit fault), symmetryamong the input currents is expected. This symmetry is checked by the device, usinga quantity monitor. The smallest phase current is compared to the largest phase cur-rent, and asymmetry is recognized if:
|Imin|/|Imax| < BAL. FACTOR I, as long as Imax /IN > BALANCE I LIMIT / IN
where Imax is the largest of the three phase currents and Imin is the smallest. The sym-metry factor BAL. FACTOR I represents the allowable asymmetry of the phase cur-rents while the limit value BALANCE I LIMIT is the lower limit of the operating rangeof this monitoring (see Figure 2-48). Both settings are adjustable, and the dropout ratiois about 97 %.
This malfunction is reported as “Fail I balance”.
Figure 2-48 current Symmetry Monitoring
Voltage Symmetry During normal system operation (i.e. the absence of a short-circuit fault), symmetryamong the input voltages is expected. Because the phase-to-phase voltages are in-sensitive to ground connections, the phase-to-phase voltages are used for the sym-metry monitoring. If the device is connected to the phase-to-ground voltages, then thephase-to-phase voltages are calculated accordingly, whereas if the device is connect-ed to phase-to-phase voltages and the displacement voltage, then the third phase-to-phase voltage is calculated accordingly. From the phase-to-phase voltages, the small-

est and largest phase-to-ground voltages are calculated and compared to check forsymmetry. Asymmetry is recognized if:
|Vmin|/|Vmax| < BAL. FACTOR V, as long as |Vmax| > BALANCE V-LIMIT
where Vmax is the largest of the three phase-to-ground voltages and Vmin is the small-est. The symmetry factor BAL. FACTOR V is the measure for the asymmetry of theconductor voltages; the limit value BALANCE V-LIMIT is the lower limit of the oper-ating range of this monitoring (see Figure 2-49). Both settings are adjustable. Thedropout ratio is about 97 %.
This malfunction is reported as “Fail V balance”.
Figure 2-49 Voltage Symmetry Monitoring
Current and Volt-age Rotation
To detect swapped phase connections in the voltage and current input circuits, thephase sequence of the phase-to-phase measured voltages and the phase currentsare checked by the monitoring.
Direction measurement with normal voltages, path selection for fault location, andnegative sequence detection all assume a phase sequence of “abc”. The phase se-quence of the phase-to-ground voltages is verified by ensuring the following
Va leads Vb leads Vc leads Va
Likewise, the phase sequence of the phase currents is verified by ensuring the follow-ing
Ia leads Ib leads Ic leads Ia
Verification of the voltage rotation occurs when each measured voltage is at least
| Vc |, |Vb |, | Va| > 40V / √3.
Verification of the current rotation occurs when each measured current is at least
|Ia|, |Ib|, |Ic| > 0.5 IN.
For abnormal phase sequences, the messages “Fail Ph. Seq. V” or “Fail Ph. Seq. I” are issued, along with the switching of this message “Fail Ph. Seq.”.
For applications in which an opposite phase sequence is expected, the protective re-lay should be adjusted via a binary input or a programmable setting. If the phase se-quence is changed in the relay, phases ‘b’ and ‘c’ internal to the relay are reversed,and the positive and negative sequence currents are thereby exchanged (see also

2.10.1.4 Description of Fuse-Failure-Monitor
Single-Phase Mea-surement VoltageLoss or Fuse Fail-ure Monitoring
In the event of a loss of measured voltage on one phase (typically due to a short circuitor broken conductor in the voltage transformer secondary circuit), the device will false-ly detect zero voltage. False detection of zero voltage can cause problems with thedirectional overcurrent protection and the undervoltage protection.
If fuses are used instead of a secondary miniature circuit breaker with connected aux-iliary contacts, then the fuse failure monitoring can detect problems in the voltagetransformer secondary circuit. If phase-to-phase voltages and the displacement volt-age are supplied to the system, then the fuse failure monitor is masked. Of course,supervision of the miniature circuit breaker and the fuse failure monitor can be usedat the same time.
If zero sequence voltage occurs, without a ground current being measured at thesame time, the device concludes that an unsymmetrical fault has occurred in the volt-age transformer secondary circuit. The processing of the displacement voltage pro-cessing of the sensitive ground fault detection and the undervoltage protection func-tions are blocked.

2.10.3 Description of Trip Circuit Monitor (74TC)
The 7SJ62/63/64 are equipped with an integrated trip circuit monitor. Depending onthe number of available binary inputs, monitoring with one or two binary inputs can beselected. If the configuration of the binary inputs needed for this does not match theselected monitoring type, then a message to this effect is sent (“74TC ProgFail”).When using two binary inputs, malfunctions in the trip circuit can be detected under allcircuit breaker conditions. When only one binary input is used, malfunctions in the cir-cuit breaker itself cannot be detected.
Monitoring withTwo Binary Inputs
When using two binary inputs, these are connected according to Figure 2-50, parallelto the associated trip contact on one side, and parallel to the circuit breaker auxiliarycontacts on the other.
A condition for the use of trip circuit monitoring is that the control voltage for the circuitbreaker is greater than the sum of the minimum voltage drops of both binary inputs(VSt > 2 ⋅ VBImin). Since at least 19 V are needed for each binary input, the monitor canonly be used with a system control voltage of over 38 V.
Figure 2-50 Principle of Trip Circuit Monitor with Two Binary Inputs
Monitoring with binary inputs not only detects interruptions in the trip circuit and lossof control voltage, it also monitors the response of the circuit breaker using the positionof the circuit breaker auxiliary contacts.
Depending on the conditions of the trip contact and the circuit breaker, the binary in-puts are activated (logical condition “H” in Table 2-10), or not activated (logical condi-tion “L”).
Even for healthy trip circuits the condition that both binary inputs are not actuated (“L”)is possible during a short transition period (trip contact is closed, but the circuit breakerhas not yet opened.) A continuous state of this condition is only possible when the tripcircuit has been interrupted, a short-circuit exists in the trip circuit, a loss of batteryvoltage occurs, or malfunctions occur with the circuit breaker mechanism.

1) Trip Circuit is faulty
The conditions of the two binary inputs are checked periodically. A check takes placeabout every 600 ms. If three consecutive conditional checks detect an abnormality (af-ter 1.8 s), an annunciation is reported (see Figure 2-51). This is used to avoid the an-nunciation for brief transition periods. When the fault in the trip circuit has beencleared, the annunciation is automatically reset.
Figure 2-51 Logic Diagram for Trip Circuit Monitoring with Two Binary Inputs
Monitoring withOne Binary Input
The binary input is connected according to figure 2-52 in parallel with the associatedtrip contact. The circuit breaker auxiliary contact 52-b is connected in series with ahigh-ohm resistor R.
The control voltage for the circuit breaker should be about two times the value of theminimum voltage drop at the binary input (VSt > 2 ⋅ VBImin). Since the minimum voltageto activate a binary input is 19 V, a DC voltage supply of 38 V or higher is required.

Monitoring Functions
Figure 2-52 Principle of Trip Circuit Monitoring with One Binary Input
During normal operation, the binary input is activated (logical condition “H”) when thetrip contact is open and the trip circuit is intact, because the monitoring circuit is closedby either the 52a circuit breaker auxiliary contact (if the circuit breaker is closed) orthrough the replacement resistor R by the 52b circuit breaker auxiliary contact. Onlyas long as the trip contact is closed, the binary input is short circuited and thereby de-activated (logical condition “L”).
If the binary input is continuously de-activated during operation, this leads to the con-clusion, there is an interruption in the trip circuit or loss of control voltage.
The trip circuit monitor does not operate during system faults. A momentary closedtripping contact does not lead to a failure message. If, however, tripping contacts fromother devices operate in parallel with the trip circuit, then the failure annunciation mustbe delayed (see also Figure 2-53). The conditions of the binary input are, therefore,checked 500 times before an annunciation is sent. A condition check takes placeabout every 600 ms, so trip circuit monitoring is only activated during an actual mal-function of the trip circuit (after 300 s). After the malfunction in the trip circuit is cleared,the failure annunciation is reset automatically.

2.10.4 Programming Settings for Trip Circuit Monitor
Trip circuit monitoring is only in effect and accessible if address 0182 was set to either2 Binary Inputs or to 1 Binary Input, and the appropriate number of binaryinputs have been masked for this purpose (refer Subsection 2.1.1). Trip circuit moni-toring can be turned ON and OFF at address 8201 FCT 74TC. If the masking of therequired binary inputs does not match the selected monitoring type, then a messageto this effect is generated (“74TC ProgFail”). If the trip circuit monitor is not to beused at all, then address 0182 should be set to Disabled. Further settings are notneeded. The message of a trip circuit interruption is delayed by a fixed amount of time.For two binary inputs, the delay is about 2 seconds, and for one binary input, the delayis about 300 s. This ensures that, for the longest possible duration of a trip signal, afalse malfunction message will not be generated.
Monitoring withOne Binary Input
NOTE: When using only one binary input (BI) for the trip circuit monitor, some mal-functions, such as interruption of the trip circuit or loss of battery voltage, can indeedbe detected, but malfunctions with closed trip contacts cannot. Therefore, the mea-surement must take place over a period of time that bridges the longest possible du-ration of a closed trip contact. This is ensured by the fixed number of measurementrepetitions and the time between the condition checks.
When using only one binary input, a resistor R is inserted into the circuit on the systemside, instead of the missing second binary input. Through appropriate sizing of the re-sistor and depending on the system relationship, a lower control voltage can often besufficient. The resistor R is inserted into the circuit of the 52b circuit breaker auxiliarycontact, to facilitate the detection of a malfunction when the 52a circuit breaker auxil-iary contact open and the trip contact has dropped out (see Figure 2-52). This resistormust be sized such that the circuit breaker trip coil is no longer energized when the

circuit breaker is open (which means 52a is open and 52b is closed). The binary inputshould still be picked up when the trip contact is simultaneously opened.
This results in an upper limit for the resistance dimension, Rmax, and a lower limit Rmin,from which the optimal value of the arithmetic mean should be selected:
In order that the minimum voltage for controlling the binary input is ensured, Rmax isderived as:
So the circuit breaker trip coil does not remain energized in the above case, Rmin isderived as:
If the calculation results that Rmax < Rmin, then the calculation must be repeated, withthe next lowest pickup threshold VBI min, and this threshold must be implemented inthe device using plug-in bridges (see Subsection 8.1.3).

Sensitive Ground Fault Detection (64, 50Ns, 67Ns)
2.11 Sensitive Ground Fault Detection (64, 50Ns, 67Ns)
General Sensitive ground fault detection may be used in isolated or compensated systems todetect ground faults. In solidly or low-resistance grounded systems, sensitive groundfault detection is used to detect high impedance ground faults.
For this protection function, the relay’s fourth current input must be equipped with asensitive input transformer (see Ordering Data in Annex A.1). Because of its high sen-sitivity, ground fault detection is not suited for detection of high magnitude groundfaults (over about 1.6 A at the sensitive ground fault detection relay terminals). Thedirectional and non-directional overcurrent protection functions are preferred for thisapplication (Sections 2.2 and ).
2.11.1 Description of Sensitive Ground Fault Detection
2.11.1.1 Voltage Element
The voltage element of sensitive ground fault detection relies on the zero sequence ordisplacement voltage V0 or 3V0. Additionally the faulty phase is determined. The dis-placement voltage V0 can be directly applied to the device, or the summary voltage3V0 can be calculated by the device based on the three phase-to-ground voltages. Inthe latter case, the three voltage inputs must be connected to voltage transformers ina grounded-wye configuration (see Subsection 2.1.3, address 0213 VT Connec-tion). If the device is only with phase-to-phase voltages, it is not possible to calculatea displacement voltage from them. In this case the direction cannot be determined.
If the displacement voltage is directly applied to the device, then V0 is the voltage atthe device terminals. It is not affected by the voltage adjustment factor set at address0206A Vph / Vdelta.
If the displacement voltage is calculated, then:
3V0 = Va + Vb + Vc
The displacement voltage is used both to detect a ground fault and to determine direc-tion, in accordance with Subsection 2.11.1.3. When the voltage element pickups, apreset time delay must elapse before detection of the displacement voltage is report-ed. This time delay is preset at the factory to 1 second and may be modified at address3111 T-DELAY Pickup. After the time delay set at address 3111 has elapsed, a sec-ond time interval may be started, after which the voltage element may initiate a trip sig-nal. This second time interval is set at address 3112 64-1 DELAY. It is important toreiterate that the total tripping time consists of the displacement voltage measurementtime (about 60 ms) plus the Pickup Time delay (set at address 3111) plus the trippingdelay (set at address 3112).
Determination ofthe GroundedPhase
After the voltage element pickups due to detection of a displacement voltage, thegrounded phase is identified, if possible. To do this, the individual phase-to-groundvoltages are measured. Of course, this is only possible if three phase-to-ground volt-ages are obtained from voltage transformers connected in a grounded-wye configura-tion. If the voltage magnitude for any given phase is below the setting value entered
1557SJ62/63/64 ManualC53000-G1140-C147-1
Functions
at address 3106 VPH MIN, that phase is detected as the grounded phase as long asthe voltage magnitudes of the other two phases are simultaneously above the settingvalue entered at address 3107 VPH MAX.
Figure 2-55 shows the logic for determining the grounded phase.
Figure 2-55 Detection of the grounded phase
2.11.1.2 Current Elements
The current elements associated with sensitive ground fault detection typically operatefor low magnitudes of zero sequence current. They are typically applied in systemswhere ground fault currents are limited by neutral resistors.
There are two current elements used for sensitive ground fault protection. A definitetime element similar to the 50N-2 or 67N-2 elements is used, as well as an elementthat may be operated with either a fixed time delay (similar to the 50N-1 and 67N-1elements) or with a user defined curve (similar to the 51N and 67N-TOC elements).Each of the elements may be directional or non-directional.
2.11.1.3 Determination of Direction
Curves When determining the sensitive ground fault direction it is not the current value that iscrucial but the part of the current which is perpendicular to a settable directional char-acteristic (axis of symmetry). As a prerequisite for determining the direction, the dis-placement voltage V0 must be exceeded as well as a configurable current part influ-encing the direction (active or reactive component).
Figure 2-56 illustrates the directional characteristic of the sensitive ground fault detec-tion function using a complex vector diagram in which the displacement voltage V0 isthe reference magnitude. Address 3125 is set to COS PHI, therefore, the current3I0real is calculated and compared with the value set at address 3123 RELEASE DIRECT.. The directional limit lines are perpendicular to 3I0real.

Figure 2-56 Directional Lines for cos-ϕ Measurement
The directional limit lines may be rotated by a correction angle set at address 3124PHI CORRECTION up to ±45°. Therefore, it is possible to increase sensitivity in theresistive-inductive range with a rotation of –45°, or in the resistive-capacitive rangewith a rotation of +45° (see Figure 2-57). If the sin-ϕ method is used, the directionallimit lines would be rotated by 90°.
If address 3124 PHI CORRECTION is set other than 0°, the angle of the directionallimit line is determined from the sum of the real and reactive components of zero se-quence power.
Figure 2-57 Directional Lines for cos-ϕ Measurement
Method ofDirectionalMeasurement
The calculation algorithm filters the measured values so that it is highly accurate andinsensitive to higher harmonics (particularly the 3rd and 5th harmonics – which are of-ten present in zero sequence currents).
Both the zero sequence or displacement voltage (V0 or 3V0) and the zero sequencecurrent (3I0) are used to determine direction to a fault or grounded connection. Beforethe determination of direction is initiated, the voltage element (and possibly the currentelement) must be picked up and a programmable component of 3I0 must exceed aprogrammable setting (address 3123 RELEASE DIRECT.).

ponent of 3I0 compared to address 3123 depends on the setting at address 3125 MEAS. METHOD. Address 3125 establishes the directional measurement method thatwill be used.
If address 3125 is set to COS j, then the component of 3I0 that is in phase with thedisplacement voltage is compared to the setting at address 3123. This current is des-ignated 3I0real, and if larger than the setting at address 3123, directional determinationis initiated. Once directional determination is initiated, the current 3I0real and the dis-placement voltage V0 (or 3V0) are used to calculate the real component of the zerosequence power supplied to the fault. Both in a grounded system and in an unground-ed system, a ground fault actually supplies zero sequence real power to the rest of thesystem. Therefore, if the calculated zero sequence real power supplied to the fault isnegative (P0<0), the fault is considered in the direction of the protected equipment (for-ward direction). If the calculated zero sequence real power supplied to the fault is pos-itive (P0>0), then the fault is considered to be in the opposite direction (reverse direc-tion). This method is typically used to determine the direction of high impedance faultsin a grounded system.
If address 3125 is set to SIN j, then the component of 3I0 that is 90° out of phasewith the displacement voltage is compared to the setting at address 3123. This currentis designated 3I0 reactive, and if larger than the setting at address 3123, directional de-termination is initiated. Once directional determination is initiated, the current3I0reactive and the displacement voltage V0 (or 3V0) are used to calculate the reactivecomponent of the zero sequence power supplied to the fault. Both in a grounded sys-tem and in an ungrounded system, a ground fault actually supplies zero sequence re-active power to the rest of the system. Therefore, if the calculated zero sequence re-active power supplied to the fault is negative (Q0<0), the fault is considered in the di-rection of the protected equipment (forward direction). If the calculated zero sequencereactive power supplied to the fault is positive (Q0>0), then the fault is considered tobe in the opposite direction (reverse direction). This method it typically used to deter-mine the direction of ground connections in an ungrounded system.
ImplementationInstructions
In an ungrounded system, the reactive component of the current should be used todetermine the direction. In a grounded system, the real component of the currentshould be used to determine the direction. Therefore, in an ungrounded system, ad-dress 3125 should be set for SIN j measurement whereas in a grounded system,address 3125 should be set for COS j measurement.
Logic Figure 2-58 illustrates the condition logic for the sensitive ground fault pickup. Groundfault pickup may be switched ON or OFF, or into Alarm Only condition at address3101 Sens. Gnd Fault. When ground fault protection is ON, tripping is possible. Inmode Alarm Only ground faults are recorded in a separate log file for ground faults.The pickup of the displacement voltage V0 starts the ground fault recording. As thepickup of the V0 stage drops out, fault recording is terminated.
The entire function may be blocked via a binary input. Switching off or blocking meansthe measurement logic (shown in Figure 2-59) is deactivated, therefore, time delaysand messages are reset.
All stages can be blocked individually via binary inputs. In this case pickups as well asdirection and grounded phase will still be reported, however, tripping does not takeplace since the time stages are blocked.

Sensitive Ground Fault Detection (64, 50Ns, 67Ns)
Figure 2-58 Activation of Sensitive Ground Fault Detection
Generation of a tripping message, for both current elements, is dependent on the di-rection selection for each element. If the element is set to non-directional and pa-rameter PU CRITERIA = Vgnd OR INs, a pickup message is generated as soon asthe current threshold is exceeded, irrespective of the status of the V0 stage. If, howev-er, the setting of parameter PU CRITERIA is Vgnd AND INs, the V0 stage must havepicked up also for non-directional mode.
But, if a direction is programmed, the current element must be picked up and the di-rection determination results must be present to generate a message. Once again, acondition for valid direction determination is that the voltage element be picked up aswell.
Based on the setting at address 3130 PU CRITERIA, the generation of a fault condi-tion message can be dependent on either the pickup of both the voltage and currentelements (AND function), or a pickup of at least one of those two elements (OR func-tion). The former may be advantageous if the pickup setting of the voltage elementwas chosen to be very low.

During configuration of protective functions, address 0131 Sens. Gnd Faultshould be set to Definite Time if the inverse characteristic is not required, User Defined PU if both a definite time and inverse time characteristic are required, andDisabled if the function is not required at all.
Also, during configuration, address 0213 VT Connection determines how the volt-age transformers are connected (phase-to-ground or phase-to-phase), and addresses

Sensitive ground fault detection may be switched ON, OFF, or to Alarm Only, at ad-dress 3101 Sens. Gnd Fault. If sensitive ground fault protection is switched ON,both tripping and message reporting is possible.
The ground fault is detected and reported only when the displacement voltage has ap-plied for at least the time T-DELAY Pickup (address 3111).
Address 3130 PU CRITERIA specifies whether ground fault detection is enabled onlyfor pickups of V0 and INs (Vgnd AND INs) or as soon as one of the two have pickedup (Vgnd OR INs).
Current Elements,General
The two time-overcurrent elements are set at addresses 3113 through 3120. Each ofthese elements may be directional or non-directional. These elements operate fromthe zero sequence current. They typically operate, therefore, only in grounded sys-tems (solid or low resistance), or for motors connected to an ungrounded bus wherethe entire system capacitance supplies zero sequence current to the motor groundconnection, but the ground current in the ground connection is insignificant becauseof the low motor capacitance.
2.11.2.2 Definite Current Stage (50Ns-2, 50Ns-1)
50Ns–2 Element The 50Ns-2 element pickup and delay settings are entered at addresses 3113 50Ns-2 PICKUP and 3114 50Ns-2 DELAY respectively. Pickup and time out of the 50Ns-2 element can result just in the generation of a message, or in both the generation ofa message and tripping. The latter is only possible if address 3101 is set to ON.
50Ns-1 / 51NsElement
If configured as Definite Time at address 0131, the 50Ns-1 element will be en-abled. The pickup and delay settings for the 50Ns-1 element are at addresses 311750Ns-1 PICKUP and 3118 50Ns-1 DELAY respectively.
2.11.2.3 Inverse Current Stage (51Ns)
51Ns Element The inverse tripping characteristic 51Ns is mainly determined by addresses 3119 and3120 (address 0131 Sens. Gnd Fault = User Defined PU).
User DefinedCurve
If a user defined curve is configured at address 0131, it should be noted that the de-vice will not necessarily pickup until the current exceeds 110 % of the pickup value, asis standard for inverse curves.
Entry of the value pair (current and time) is a multiple of the settings at addresses3119 51Ns PICKUP and 3120 51Ns TIME DIAL. Therefore, it is recommended thataddresses be initially set to 1.00 for simplicity. Once the curve has been entered, thesettings at addresses 3119 and 3120 can be modified if desired.
As delivered, The default settings for all current values is ∞. They are, therefore, notenabled — and no pickup or tripping of these protective functions will occur.
Up to 20 pairs of values (current and time) may be entered at address 3131 M.of PU TD. The device then approximates the curve, using linear interpolation.
162 7SJ62/63/64 ManualC53000-G1140-C147-1
Sensitive Ground Fault Detection (64, 50Ns, 67Ns)
The following must be observed:
− The value pairs should be entered in increasing sequence. If desired, fewer than 20pairs may be entered. In most cases, about 10 pairs is sufficient to define the curveaccurately. Each unused pair must then be marked as unused by entering “∞” asthe limit value. The user must ensure the value pairs produce a clear and constantcurve.
− The current values entered should be those from Table 2-13, along with the match-ing times. Other values for MofPU are changed to the nearest adjacent value al-though this is not indicated.
− Current flows less than the smallest current value entered will not lead to an exten-sion of the tripping time. The pickup curve (see Figure 2-62) continues, from thesmallest current point parallel to the current axis.
− Current flows greater than the highest current value entered will not lead to an ab-breviation of the tripping time. The pickup curve (see Figure 2-62) continues, fromthe largest current point parallel to the current axis.

2.11.2.4 Phase-to-Ground Voltage
Determination ofthe Phase with aGroundConnection
The phase connected to ground may be identified in an ungrounded system, if the de-vice is supplied by three voltage transformers connected in a grounded-wye configu-ration. The phase whose voltage lies below the minimum voltage setting at address3106 VPH MIN is identified as the phase connected to ground as long as the othertwo phase voltages simultaneously exceed the maximum voltage setting at address3107 VPH MAX. The setting at address 3106 must be set less than the minimum al-lowable phase-to-ground voltage. A typical setting for this address would be 40 V. Themaximum voltage setting at address 3107 must be greater than the minimum allow-able phase-to-ground voltage, but less than the minimum phase-to-phase voltage. ForVN = 100 V, approximately 75 V is a typical setting. These settings have no signifi-cance in a grounded system.
Displacement Volt-age V0 or 3V0
The pickup due to displacement voltage is set at address 3109 64-1 VGND if V0 ismeasured or address 3110 64-1 VGND if 3V0 is calculated. Pickup of the voltage el-ement is a condition for initiation of directional determination. Depending on the settingat 0213 VT Connection, only the applicable limit value at address 3109 or 3110 isaccessible. That is, if two phase-to-phase voltages and the displacement voltage V0are supplied to the device, the measured displacement voltage is used directly forground fault recognition. The limit value for V0 is programmed at address 3109, wherea more sensitive setting can be made. If three phase-to-ground voltages are connect-ed to the device, the displacement voltage 3V0 is calculated from the three phase-to-ground voltages, and address 3110 is where the voltage element pickup is set. Theground connection is first detected and reported when the displacement voltage hasexisted for the entire time delay set at address 3111 T-DELAY Pickup.
With regard to an ungrounded system, nearly the entire displacement voltage appearsat the device terminals, therefore the pickup setting is not critical, and typically lies be-tween 30 V and 60 V (address 3109) or 50 V and 100 V (address 3110). Large faultresistances may require higher sensitivity (i.e. a lower pickup setting).With regard to a grounded system, a more sensitive (lower) pickup value may be set,but it must be above the maximum anticipated displacement voltage during normal(unbalanced) system operation.
Trip Time Delay Pickup of just the voltage element may initiate time delayed tripping depending on thesetting at address 3130 PU CRITERIA (address 3101 Sens. Gnd Fault = ON) andmoreover address 3130 PU CRITERIA is configured Vgnd OR INs. The trippingdelay is then set at address 3112 64-1 DELAY. It is important to note that the totaltripping time consists of the displacement voltage measurement time (about 50 ms)plus the pickup time delay (address 3111) plus the tripping time delay (address 3112).

Sensitive Ground Fault Detection (64, 50Ns, 67Ns)
The direction of the definite high-set stage 67Ns-1 or of the inverse characteristic maybe set at address 3122 67Ns-1 DIRECT. as Forward, Reverse or Non-Direc-tional.
The current setting at address 3123 RELEASE DIRECT. supervises the initiation ofdirectional determination, and is based on the current components which are perpen-dicular to the directional limit lines. The position of the directional limit lines themselvesare based on the settings entered at address 3124 PHI CORRECTION and 3125MEAS. METHOD.
When address 3124 PHI CORRECTION is set to 0.0°, the following apply to address3125:
− Address 3125 = COS j: the real component of the zero sequence current with re-spect to the displacement voltage (the component of 3I0 in phase with V0 or 3V0) isevaluated by the setting at address 3123 (see Figure 2-56);
− Address 3125 = SIN j: the reactive (capacitive) component of the zero sequencecurrent with respect to the displacement voltage (the component of 3I0 that leadsV0 or 3V0 by 90°) is evaluated by the setting at address 3123 (see Figure 2-63).

− The directional line, in this respect, may be rotated within the range ±45° — asshown in Figure 2-57.
UngroundedSystem
In an ungrounded system, no zero sequence fault current exists, therefore, the zerosequence charging current must be used for directional determination. As is the casewith the zero sequence fault current, the zero sequence charging current will also leadthe zero sequence voltage for a fault in the forward direction. A setting equal to abouthalf of this current should be selected at address 3123. The measurement time se-lected at address 3125 should be SIN j.

Grounded System In a grounded system, address 3123 should be set below the minimum anticipatedground fault current. It is important to note that only the current components that areperpendicular to the directional limit lines defined at addresses 3124 and 3125 will beevaluated. COS j is the type of measurement used, and the correction angle is set to–45°, since the ground fault current is typically resistive-inductive (right portion of Fig-ure 2-57).
Electrical Motors One may set the value COS j for the measurement type and use a correction angleof +45° for electrical motors supplied from a common bus in an ungrounded system,since the ground connection current is often composed of an overlap of the capacitiveground current from the system and the resistive current of the load resistance (Figure2-57, left section).
General The following is valid for determination of direction during ground faults: The minimumcurrent for directional determination entered at address 3123 RELEASE DIRECT. must be set as high as possible so as not to be a false limit of the device during theflow of asymmetrical currents in the system.
If direction determination is used in conjunction with one of the current elements dis-cussed above (50Ns-1 PICKUP or 51Ns PICKUP), a value for address 3123 is onlysignificant if it is less than or equal to the current element pickup value.
A corresponding message (reverse, forward, or undefined) is issued upon directiondetermination. To avoid chatter for this message resulting from sharply-varying groundconnection currents, a dropout delay RESET DELAY, entered at address 3126, is ini-tiated when directional determination drops out, and the message is held for this peri-od of time.
2.11.2.6 Current Transformer
Angular ErrorCompensation
Addresses 3102 through 3105 only apply to compensated systems which utilize Pe-tersen coils. Since the utilization of compensated systems is primarily limited to Euro-pean practices, a detailed explanation of these settings is beyond the scope of thisparticular instruction manual. In the rare event that this protective relay is utilized in acompensated system, the reader should contact Siemens Power T&D for more infor-mation regarding application of the 7SJ62/63/64 relay in a compensated system.
2.11.2.7 Settings for Sensitive Ground Fault Detection
The current-based setting ranges and Default Setting values are independent of thenominal current rating of the device. The sensitive ground fault detection measuresthe current at a special, sensitive input. In general, current-based settings can be en-tered in primary terms with consideration given to the ratio of the applicable currenttransformer. However, problems related to the resolution of the pickup currents canoccur when very small settings and small primary currents are involved. The user istherefore encouraged to enter settings for the sensitive ground fault detection in sec-ondary terms.

2.12 Intermittent Ground Fault Protection
General Intermittent ground faults can occur in cables due to poor insulation or water ingressin cable joints. Often such faults disappear automatically to strike again after sometime. They can last between a few milliseconds and several seconds. This is why suchfaults are not detected at all or not selectively by the ordinary time overcurrent protec-tion. If pulse durations are extremely short, not all protection devices in a short-circuitpath may pick up; selective tripping is thus not ensured.
Due to the time delay of the overcurrent protection function such faults are too shortto initiate shutdown of the faulted cable. Only when they have become permanent cansuch ground faults be removed selectively by the short-circuit protection.
But such intermittent ground faults already bear the risk of causing thermal damage toequipment. This is why the 7SJ62/63/64 device features a protective function that isable to detect such intermittent ground faults and accumulates their duration. If withina certain time their sum reaches a configurable value, the thermal load capacity hasbeen achieved. If the ground faults are distributed over a long period of time or if theground fault goes off and does not re-ignite after some time, the eqiupment under loadis expected to cool down. Tripping is not necessary in this case.
2.12.1 Functional Description
The intermittent ground fault can either be detected via the ground current input I4 (INor INs) or it is calculated from the sum of the three phase currents (3I0). Unlike theovercurrent protection which uses the fundamental wave, the intermittent ground faultprotection creates the r.m.s. value of this current and compares it to a configurablethreshold Iie>. This method accounts for high harmonic contents (up to 400 Hz) andfor the direct component since both factors contribute to the thermal load. Exceedingthe threshold value Iie> initiates a pickup message (“IIE Fault det“, see Figure2-64). The pickups are also counted; as soon as the counter content has reached thevalue of parameter Nos.det., the message “Intermitt.EF“ is issued. A stabilizedpickup is obtained by prolonging the pickup message “IIE Fault det“ by a settabletime T-det.ext. This stabilization is especially important for coordination with exist-ing static or electromechanical relays.
The duration of the stabilized pickups “IIE stab.Flt“ is summed up in an integratorT-sum det. If the accumulated pickup time reaches a configurable threshold value,a corresponding message is generated (“IEF Tsum exp.“) and tripping takes place,however, only while a ground fault is present (message “IEF Trip“). The trip com-mand is maintaned during the entire minimum tripping time specified for the device,even if the ground fault is of short duration. After completion of the tripping commandall memories are reset and the protection resumes normal condition.
The (much longer) resetting time T-reset (message “IEF Tres run.“) is launchedsimultaneously with T-sum det. when a ground fault occurs. Unlike T-sum det.each new ground fault resets this time to its initial value and it expires anew. If T-re-set expires and no new ground fault is recorded during that time, all memories arereset and the protection resumes normal position. T-reset thus determines the timeduring which the next ground fault must occur to be processed yet as intermittentground fault in connection with the previous fault. A ground fault that occurs later willbe considered a new fault event.
170 7SJ62/63/64 ManualC53000-G1140-C147-1
Intermittent Ground Fault Protection
The message “IIE Fault det“ will be entered in the fault log and reported to thesystem interface only until the message “Intermitt.EF“ is issued. This prevents aburst of messages. If the message is allocated to an LED or a relay, this limitation doesnot apply. This is accomplished by doubling the message (message numbers 06924,06926).
Interaction withAutomaticReclosure
Automatic reclosure is not an effective measure against intermittent ground faults asthe function only trips after repeated detection of a fault or after expiration of the sum-mation monitoring time T-sum det. and besides its basic design is to prevent ther-mal overload. For these reasons the intermittent ground fault protection is not imple-mented as starting feature of the automatic reclosing function.
Interaction withBreaker FailureProtection
A pickup that is present when the time delay TRIP-Timer has expired is interpretedby the breaker failure protection as a criterion for a tripping failure. Since permanentpickup is not ensured after a tripping command of the intermittent ground fault protec-tion, cooperation with the breaker failure protection is not reasonable. Therefore, thisfunction is not activated by the intermittent ground fault protection.

Figure 2-64 Logic diagram of the protection for intermittent ground fault – Principle
Fault Logging A fault event and thus fault logging is initated when the Interm. E/F detection stage Iie>first picks up. The message “IIE Fault det“ is issued and entered in the fault log(and reported to the system interface) so often until the number of pickups “IIE Fault det“ has reached the value set for parameter “Nos.det.“. When this hap-pens, the message “Intermitt.EF“ is issued and “IIE Fault det“ is blocked forthe fault log and the system interface. This method accounts for the fact that the In-term. E/F detection stage Iie> may also pick up for a normal short-circuit. In this casethe pickup does not launch the alarm “Intermitt.EF“.
Intermittent ground faults may cause other time overcurrent stages to pick up (e.g. 50-1, 50N-1, 50Ns-1) and produce a burst of messages. To avoid overflow of the fault logsuch messages are not entered anymore in the fault log after detection of an intermit-

Functions
Before they are entered in the fault log (event buffer) and transmitted to the systeminterface or CFC, the messages of table 2-15 are buffered (starting with the first pickupmessage received after “Intermitt.EF” was signalled). The buffering does not ap-ply for signalling to relays and LEDs as it is required by time-graded protection sys-tems for reverse interlocking. The intermediate buffer can store a maxium of two sta-tus changes (the most recent ones) for each message.
Buffered messages are signalled to the fault log, CFC and to the system interface withthe original time flag only when a TRIP command is initiated by a protective functionother than the intermittent ground fault protection. This ascertains that a pickup, al-though delayed, is always signalled in association with each TRIP command.
All pickup messages which usually do not occur during an intermittent ground fault arenot affected by this mechanism. Among others this includes the pickup and TRIP com-mands of the following protective functions:
• Breaker failure protection,
• Overload protection,
• Frequency protection and
• Voltage protection.
The pickup signals of these functions will still be logged immediately. A TRIP com-mand of one of these protective functions will cause the buffered messages to becleared since no connection exists between tripping function and buffered message.
A fault event is cleared when the time T-reset has expired or the TRIP command“IEF Trip“ has been terminated.

Intermittent Ground Fault Protection
Terminating a fault event for the intermittent ground fault protection thus is a specialcase since it is the time T-reset that keeps the fault event opened and not the pick-up.
2.12.2 Functional Settings
General Protection against intermittent ground faults can only take effect and is only accessibleif the current to be evaluated (with Ignd, with 3I0 or with Ignd,sens.) wasconfigured in address 0133 INTERM.EF. If the function is not needed, it is set to Dis-abled.
In address 3301 INTERM.EF you can switch the function to ON or OFF.
The pickup threshold (r.m.s. value) is set in address 3302 Iie>. A rather sensitivesetting is possible to respond also to short ground faults since the pickup time shortensas the excess current increases. The setting range depends on the selection of thecurrent to be evaluated at address 0133 INTERM.EF.
The pickup time can be prolonged at address 3303 T-det.ext.. This pickup stabi-lization is especially important for the coordination with existing analog or electrome-chanical overcurrent relays. The time T-det.ext. can also be disabled (T-det.ext. = 0).
The stabilized pickup starts the counter Tsum. This counter is stopped but not reset asthe picked up function drops out. Basing on the last counter content the counter re-sumes metering when the stabilized function picks up next. This sum of individualpickup times, which are to initiate tripping, is set at address 3304 T-sum det. Itserves as selectivity criterion for coordinating the relays of one busbar run and is com-parable to the time grading of the time overcurrent protection. The relay in the radialnetwork which is closest to the intermittent fault and picks up, is set to the shortestsummation time T-sum det. (see Figure 2-65).
Figure 2-65 Example of the setting of the time stage T-sum det.
The reset time T-reset, after which the summation is reset in healthy operation andthe protection resumes normal status, is configured at address 3305.
Address 3306 Nos.det. specifies the number of pickups after which a ground faultis considered intermittent.

Automatic Reclosing System (79M)
2.13 Automatic Reclosing System (79M)
2.13.1 Description of Automatic Reclosing System
2.13.1.1 General
From experience, the majority of faults associated with overhead distribution feedersare temporary in nature. Therefore, to maximize service availability, it is desirable toemploy a system that will close the circuit breaker shortly after it is tripped. This is ac-complished in the 7SJ62/63/64 relay via the automatic reclosing system.
When using the automatic reclosing system, if the fault still exists after the circuitbreaker has been reclosed, then the protective elements will re-trip the circuit breaker.Depending on the number of reclosing attempts programmed for the automatic reclos-ing system (up to nine are possible), the circuit breaker will either be reclosed again,or will remain open.
The automatic reclosure system can also operate in interaction with the integratedsynchronizing function or with an external synchrocheck.
Figure 2-66 shows an example of a timing diagram for a successful second reclosure.

The automatic reclosing function can also be initiated by an external protection relay.For this application, an output contact from the tripping relay must be wired to a binaryinput of the 7SJ62/63/64 relay. It is also possible to allow the 7SJ62/63/64 relay towork in conjunction with an external reclosing device.
The trip commands initated by the automatic reclosure function are counted. A statis-tical counter is available for this purpose for the first and all subsequent reclosing com-mands.
The automatic reclosing function is typically utilized only in situations where the occur-rence of temporary faults is anticipated. Therefore, the automatic reclosing system isnot applied when the 7SJ62/63/64 relay is used to protect generators, motors, trans-formers, and cables.

grammed such that any of the elements of table 2-16 can initiate (Starts 79), notinitiate (No influence), or block reclosing (Stops 79).:
If an element initiates reclosing, the appropriate reclosing program is executed.
The binary input messages 02715 “>Start 79 Gnd“ and 02716 “>Start 79 Ph“ for starting an automatic reclosure program can also be activated via CFC (fast PLCtask processing). Automatic reclosure can thus be initiated via any messages (e.g.protective pickup) if address 7164 BINARY INPUT is set to Starts 79.
Operating Time The operatng time serves for monitoring the time between a general device pickupand the trip command of a protective function configured as starter. The operating timeis launched when pickup of any function is detected, irrespective of whether this func-tion interacts with the automatic reclosure program or not. If a protective function con-figured as starter initiates a trip command during the operating time, the automatic re-closure program is started. Trip commands of a protective function configured as start-er occurring in the time between expiration of the operating time and dropout of thegeneral device pickup cause the dynamic blocking of the automatic reclosing program.Trip commands of protective functions which are not configured as starter do not affectthe operative time.
If the automatic reclosure program interacts with an external protection device, thegeneral device pickup for start of the operating time is communicated to the automaticreclosing program via binary input 02711 “>79 Start“.
ReclosingPrograms
Depending on the type of fault, two different reclosing programs can be used. The fol-lowing applies:
• The single phase fault (ground fault) reclosing program applies if a phase-to-groundfault is detected. Therefore, the ground fault reclosing program is executed onlywhen the elements associated with a specific phase and/or ground pick up. Thisprogram can also be started via a binary input.
• The multiple phase fault (phase fault program) reclosing program applies to all othercases. That is, when elements associated with two or more phases pickup, with orwithout the pickup of ground elements, the phase reclosing program is executed. Inaddition, when automatic reclosing is initiated by other functions, such as negativesequence elements, the program is started. Like the ground fault reclosing pro-gram, this program can be started via a binary input as well.
The reclosure program evaluates only elements that pick up as elements dropping outmay corrupt the result if they drop out at differen times when opening the circuit break-er. Therefore, the ground fault reclosure program is executed only when the elements

associated with one particular phase pick up until the circuit breaker is opened; all oth-ers will initate the phase fault program.
For each of the programs, up to 9 reclosing attempts can be separately programmed.The open breaker times preceding the first four reclosing attempts can be indepen-dently set, however, the open breaker times preceding the fifth through the ninth re-closing attempts will correspond to the open breaker time that precedes the fourth re-closing attempt.
Reclosing BeforeSelectivity
For the automatic reclosure sequence to be successful, faults on any part of the linemust be cleared from the feeding line end(s) within the same – shortest possible –time. Usually, therefore, an instantaneous protection element is set to operate beforean automatic reclosure. In addition, when two or more reclosing attempts are antici-pated, high speed tripping should be allowed. To begin with, high speed tripping min-imizes the impact fault current might have on the system. Second, high speed trippingprevents the operation of load side fuses for temporary faults. Prior to the final reclos-ing attempt, however, high speed tripping should be defeated to prevent a feeder lock-out from occurring due to faults beyond load side protective devices.
Single-ShotReclosing
When a trip signal is programmed to initiate the automatic reclosing system, the ap-propriate automatic reclosing program will be executed. Once the circuit breaker hasopened, the programmable dead time interval is started (see also side title “ReclosingPrograms“). Once the dead time interval has elapsed, a closing signal is issued to re-close the circuit breaker. A blocking time interval TIME RESTRAINT is started at thesame time. If a new fault occurs before the blocking time elapses, the automatic re-closing system is dynamically blocked causing the final tripping of the circuit breaker.
The dead time can be set individually for each of the two reclosing programs.
Criteria for opening the circuit breaker may either be the auxiliary contacts of the circuitbreaker or the dropout of the general device pickup if auxiliary contacts are not con-figured.
If the fault is cleared (successful reclosing attempt), the blocking time expires and au-tomatic reclosing is reset in anticipation of a future fault.
If the fault is not cleared (unsuccessful reclosing attempt), then a final tripping signalis initiated by one or more protective elements.
Multi-ShotReclosing
The 7SJ62/63/64 relay can be programmed to initiate up to nine (9) reclosing at-tempts. The number of reclosing attempts can be set differently for the phase fault re-closing program and the ground fault reclosing program. The first dead time intervalprecedes, in principle, the first reclosing attempt. If the first reclosing attempt is unsuc-cessful, the blocking time interval is reset and the second dead time interval begins.At the end of the second open breaker interval, a second reclosing attempt is initiated.This cycle can be repeated until the allowable number of reclosing attempts pro-grammed have been made.
The dead time intervals preceding the first four (4) reclosing attempts can be set dif-ferently for each of the two reclosing programs. The dead time intervals preceding thefifth (5) through the ninth (9) reclosing attempts will be equal to the dead time intervalthat precedes the fourth (4) reclosing attempt.
If one of the reclosing attempts is successful, the blocking time expires and the auto-matic reclosing system is reset.
180 7SJ62/63/64 ManualC53000-G1140-C147-1
Automatic Reclosing System (79M)
If none of the reclosing attempts is successful, then a final circuit breaker trip will takeplace after the last allowable reclosing attempt has been made.
After the final circuit breaker trip, the automatic reclosing system is dynamicallyblocked (see below).
Blocking Time The function of the blocking time has already been described in the paragraphs at sidetitle “Single-/Multi-Shot Reclosing”. The blocking time can be prolonged when the fol-lowing conditions are fulfilled.
The time TMax CLOSE CMD defines the maximum time during which a close com-mand applies. If a new trip command occurs before this time has run out, the closecommand will be terminated. If the time TMax CLOSE CMD is set higher than the block-ing time TIME RESTRAINT, the blocking time will be extended after expiry to the re-maining close command duration.
Likewise, a pickup from a protective function that is set to initiate the automatic reclos-ing system will lead to an extension of the blocking time!
Static Blocking Static blocking means that the automatic reclosing system is not ready to initiate re-closing, and cannot initiate reclosing as long as the blocking signal is present. Whenstatic blocking takes place, a corresponding message is generated (“79 is NOT ready“). The static blocking signal is also used internally to block the protection ele-ments that are only supposed to work when reclosing is enabled (see also side title“Reclosing Before Selectivity“ further above).
The automatic reclosing system is statically blocked for one or more of the following:
− A blocking signal (FNo. 02703 “>BLOCK 79”) is present at a binary input, if the au-tomatic reclosing system is not initiated (associated message: “>BLOCK 79“).
− A signal (FNo. 02730 “>CB Ready”) indicating the circuit breaker is ready disap-pears from a binary input, if the automatic reclosing system is not initiated (associ-ated message “>CB Ready“).
− The number of allowable reclosing attempts set for both reclosing programs is zero(associated message: “ 79 no cycle“).
− No protective functions (parameters 7150 to 7163) or binary inputs are set to ini-tiate the automatic reclosing system (associated message:” 79 no starter“).
− The circuit breaker position is reported as being “open” and no trip command ap-plies (associated message: “ 79 BLK: CB open“). This presumes that 7SJ62/63/64 be informed on the condition of the trip contact via the auxiliary contacts of thecircuit breaker.
Dynamic blocking/lock out
Dynamic blocking of the automatic reclosure program occurs in those cases where thereclosure program is active and one of the conditions for blocking is fulfilled. The dy-namic blocking is signalled by the message “79 DynBlock“. The dynamic blockingfunction is associated with the configurable lock-out time SAFETY 79 ready. Thislock-out time is usually started by a blocking condition that has been fulfilled. After thelock-out time has elapsed the device checks whether or not the blocking condition canbe reset. If the blocking condition is still present or if a new blocking condition is ful-filled, the lock-out time is restarted. If, however, the blocking condition no longer holdsafter the lock-out time has elapsed, the dynamic blocking will be reset.
1817SJ62/63/64 ManualC53000-G1140-C147-1
Functions
Dynamic blocking/lock out is initiated if:
− The maximum number of reclosure attempts has been achieved. If a trip commandnow occurs within the lock-out time, the automatic reclosure program will beblocked dynamically, (indicated by “ 79 Max. No. Cyc“)
− The protection function has detected a three-phase fault and the device is pro-grammed (3Pol.PICKUP BLK) not to reclose into three-phase faults, (indicated by“79 BLK:3ph p.u. “).
− the operating time has elapsed without a TRIP command being issued, each TRIPcommand that occurs after the operating time has expired and before the picked-up element drops out, will initiate the dynamic blocking (indicated by “79 Tact ex-pired“).
− A protective function trips which is to block the automatic reclosure function (as con-figured). This applies irrespective of the status of the automatic reclosure system(started / not started) if a TRIP command of a blocking element occurs (indicatedby “79 BLK by trip “).
− The circuit breaker failure function is initiated.
− The circuit breaker does not trip within the configured time T-Start MONITOR af-ter a trip command was issued thus leading to the assumption that the circuit break-er has failed. (The breaker failure monitoring is primarily intented for VSI purposes.VSI safety checks are often conducted with the circuit breaker disconnected. Thebreaker failure monitoring prevents unexpected reclosing after the circuit breakerhas been reconnected, indiciated by “79 T-Start Exp“).
− The circuit breaker is not ready after the breaker monitoring time has elapsed, pro-vided that the circuit breaker check has been activated (address 7113 CHECK CB?= Chk each cycle, indicated by “79 T-CBreadyExp“),
− The circuit breaker is not ready after maximum extension of the dead time Max. DEAD EXT.. The monitoring of the circuit breaker status and the synchrocheck maycause undesired extension of the dead time. To prevent the automatic reclosuresystem from assuming an undefined state, the extension of the dead time is moni-tored. The extension time is started when the regular dead time has elapsed. Whenit has elapsed, the automatic reclosure function is blocked dynamically and the lock-out time launched. The automatic reclosure system resumes normal state when thelock-out time has elapsed and new blocking conditions do not apply (indicated by“79 TdeadMax Exp“) .
− Manual closing has been detected (externally) and parameter BLOCK MC Dur. (T≠ 0) was set such that the automatic reclosing system responds to manual closing,
− Via a correspondingly marshalled binary input (FNo. 02703 “>BLOCK 79“). If theblocking takes places while the automatic recloser is in normal state, the latter willbe blocked statically (“79 is NOT ready“). The blocking is terminated immedi-ately when the binary input has been cleared and the automatic reclosure functionresumes normal state. If the automatic reclosure function is already running whenthe blocking arrives, the dynamic blocking takes effect (“79 DynBlock“). In thiscase the activation of the binary input starts the lock-out time SAFETY 79 ready.Upon its expiration the device checks if the binary input is still activated. This thecase, the automatic reclosure program changes from dynamic blocking to staticblocking. If the binary input is no longer active when the time has elapsed and if nonew blocking conditions apply, the automatic reclosure system resumes normalstate.

Automatic Reclosing System (79M)
Circuit BreakerStatus
The detection of the actual circuit breaker position is necessary for the correct func-tionality of the auto reclose function. The breaker position can be detected via thebreaker contacts and the binary inputs 04602 “>52-b“ and 04601 “>52-a“. Themethod to be used depends on the masking of the binary inputs: “>52-a” (FNo.04601) and “>52-b” (FNo. 04602). The following applies:
• If binary input 04601 „>52-a“ and binary input 04602 „>52-b“ are used, the auto-matic reclosure function can detect whether the circuit breaker is open, closed or inintermediate position.If the circuit breaker is open or in intermediate position without a trip command be-ing present, the automatic reclosure function is blocked dynamically if it is alreadyrunning. If the automatic reclosure system is in normal state, it will be blocked stat-ically. When checking whether a trip command applies, all trip commands of the de-vice are taken into account irrespective of whether the function acts as starting orblocking element on behalf of the automic reclosure program.
• If binary input 04601”>52-a“ alone is allocated, the circuit breaker is consideredopen while the binary input is not active.If the binary input becomes inactive while no trip command of (any) function applies,the automatic reclosure system will be blocked. The blocking will be of static natureif the automatic reclosure system is in normal state at this time. If the automatic re-closing system is already running, the blocking will be a dynamic one.The dead time is started if the binary input becomes inactive following the trip com-mand of a starting element. An intermediate position of the circuit breaker cannotbe detected for this type of allocation.
• If binary input 04602 “>52-b“ alone is allocated, the circuit breaker is consideredopen while the binary input is active.If the binary input becomes active while no trip command of (any) function applies,the automatic reclosure system will be blocked dynamically provided it is alreadyrunning. Otherwise the blocking will be a static one.The dead time is started if the binary input becomes active following the trip com-mand of a starting element. An intermediate position of the circuit breaker cannotbe detected for this type of allocation.
• If neither binary input 04602 “>52-b“ nor 04601 “>52-a“ are allocated, the auto-matic reclosure program cannot detect the position of the circuit breaker. In thiscase, the automatic reclosure system will be controlled exclusively via pickups andtrip commands. Monitoring for “52-b without TRIP” and starting the dead time in de-pendence of the circuit breaker feedback is not possible in this case.
Circuit BreakerMonitoring
The ability of a circuit breaker to reclose and re-trip if necessary can be monitored bythe 7SJ62/63/64 relay.
A precondition for a reclosing attempt, following a trip command initiated by a protec-tive relay element and subsequent initiation of the automatic reclosing function, is thatthe circuit breaker is ready for at least one TRIP-CLOSE-TRIP cycle. The readinessof the circuit breaker is monitored by the device using a binary input (“>CB Ready”).In the case where this signal from the breaker mechanism is not available, the circuitbreaker monitoring feature should be disabled, otherwise reclosing attempts will re-main blocked.
− When multiple reclosing attempts are programmed, it is a good idea to monitor thecircuit breaker condition prior to each reclosing attempt as well, since operation of,for example, pneumatically controlled circuit breakers will result in reduced air pres-sure. A reclosing attempt will be blocked until the binary input, configured with the
1837SJ62/63/64 ManualC53000-G1140-C147-1
Functions
function 02730,indicates that the circuit breaker is ready to complete anotherCLOSE-TRIP cycle.
− The recovery time of the circuit breaker can be monitored by the 7SJ62/63/64 relay.The monitoring time CB TIME OUT expires for as long as the circuit breaker doesnot indicate that it is ready via binary input “>CB Ready“ (FNo. 02730). Meaningthat as the binary input “>CB Ready“ is cleared, the monitoring time CB TIME OUTis started. If the binary input returns before the monitoring time has elapsed, themonitoring time will be cancelled and the reclosure process is continued. If the mon-itoring time runs longer than the dead time, the dead time will be extended accord-ingly. If the monitoring time elapses before the circuit breaker signals its readiness,the automatic reclosure function will be blocked dynamically.
Interaction with the synchronizing function may cause the dead time to extend inad-missibly. To prevent the automatic reclosure function from remaining in an undefinedstate, dead time extension is monitored. The maximum extension of the dead time canbe set at Max. DEAD EXT..
The monitoring time Max. DEAD EXT. is started when the regular dead time haselapsed. If the synchronizing function responds before the time has elapsed, the mon-itoring time will be stopped and the close command generated. If the time expires be-fore the synchronizing function reacts, the automatic reclosure function will be blockeddynamically.
Please make sure that the above mentioned time is not shorter than the monitoringtime CB TIME OUT.
The time 7114 T-Start MONITOR serves for monitoring the response of the auto-matic reclosure function to a breaker failure. It is activated by a trip command arrivingbefore or during a reclosing operation and marks the time that passes between trip-ping and opening of the circuit breaker. If the time elapses, the device assumes abreaker failure and the automatic reclosure function is blocked dynamically. If param-eter T-Start MONITOR is set to ∞, the start monitoring is disabled.
2.13.1.3 Controlling Protective Stages
Depending on the reclosing cycle it is possible to control stages of the directional andnon-directional overcurrent protection by means of the automatic reclosure system.Protective stage control implies that,
1. time overcurrent stages may trip instantaneously depending on the automatic re-closure cycle (T = 0), they may remain unaffected by the auto reclosing functionAR (T = T) or may be blocked (T = ∞).
2. time overcurrent stages can be influenced via the cold load pickup function (seeSection 2.4) regarding thresholds and trip time delays depending on whether theautomatic reclosure system is ready or not.
Control of the overcurrent protection stages takes effect by releasing the cycle markedby the corresponding parameter. The cycle zone release is indicated by the messages“79 1.CycZoneRel“ through “79 4.CycZoneRel“. If the automatic reclosure sys-tem is in normal state, the settings for the starting cycle apply. Consequently, their set-tings always take effect when the automatic reclosure system assumes normal state.
The settings are released for each following cycle by issuing the close command andstarting the blocking time. Following a successfull auto reclosing operation (blockingtime elapsed) or when reset after blocking, the automatic reclosure system assumes
184 7SJ62/63/64 ManualC53000-G1140-C147-1
Automatic Reclosing System (79M)
normal state. Control of the protection is again assumed by the parameters for thestarting cycle.
Figure 2-68 shows an example of protection stages control
Figure 2-68 Control of protection stages for two-fold, successful auto reclosure
Example:
Before the first reclosure faults are to be eliminated quickly applying stages 50-2 or50N-2. Fast fault termination thus has priority over selectivity aspects as the reclosingaction aims at maintaining normal system operation. If the fault prevails, a second trip-ping is to take place instantaneously and a second reclosure.
After the second reclosure, however, stages 50-2 or 50N-2 are to be blocked so thefault can be eliminated applying stages 50-1 or 50N-1 according to the network’s timegrading schedule giving priority to selectivity concerns.

bef.3.Cy:50-2 and 7227 bef.3.Cy:50N-2 are set to blocked T= causingstages 50-2 and 50N-2 to be blocked after the second reclosure. The back-up stagese.g., 50-1 and 50N-1 must obviously not be blocked (addresses 7200, 7201, 7212,7213, 7224 and 7225).
The blocking applies only after reclosure according to the settings address. Hence, itis possible to specify again other conditions for a third reclosure.
The blocking conditions are also valid for the zone sequence coordination, provided itis available and activated (address 7140, see also Subsection 2.13.1.4, “Zone Se-quence Coordination1)“).
2.13.1.4 Zone Sequence Coordination1)
It is the task of the zone sequence coordination to harmonize the automatic reclosurefunction of this device with that of another device that is part of the same power sys-tem. It is a complementary function to the automatic reclosure program and allows forexample to perform group reclosing operations in radial systems. In case of multiplereclosures, groups may also be in nested arrangement and further high-voltage fusescan be overgraded or undergraded.
Zone sequencing works by blocking certain protective functions depending on the re-close cylce. This is implemented by the protective stages control (see Subsection2.13.1.3).
As a special feature, changing from one reclosing cycle to the next is possible withouttrip command only via pickup/dropout of stage 50-1 or 50N-1.
Figure 2-69 shows an example of how zone sequencing and protection of load sidefuses is possible in a radial distribution system. Consider the relays protecting Feeder#3 and the busbar. Assume that the relay protecting Feeder #3 is programmed for onereclosing attempt and that the busbar relay does not utilize reclosing.
For fault F1 at Tap Line #2, the 50-2 elements associated with both the Feeder #3 re-lay and the busbar relay pickup. The time delay of the 50-2 element protecting Feeder#3 is set so that the Feeder #3 circuit breaker will clear the fault before the fuse at TapLine #2 is damaged. After the first reclosing attempt, if the fault was cleared, normalservice is restored to all customers (including the customers served by Tap Line #2).If after the first reclosing attempt, the fault continues to exist, the 50-2 element at Feed-er #3 is blocked, and the fuse operates to clear the fault. If the fuse fails to clear thefault, then the 50-1 element protecting Feeder #3 will initiate a delayed trip signal (0.4seconds), thus serving as backup protection for the fuse.
Assume protection requirement require that the 50-2 element at the busbar relay beset with a delay of 0.4 seconds as well. When the fault first appears at F1, the 50-2element at the bus relay picks up, but drops out when the 50-2 element at Feeder #3trips the circuit breaker. Upon reclosing, if the fault still remains, the 50-2 element as-sociated with the bus relay picks up again, however, the fuse operates to clear thefault, thus resulting in a drop out of the 50-2 element at the busbar relay. Had the faultbeen on Feeder #3, however, the 50-2 element associated with the busbar relay wouldhave initiated a trip (simultaneously with the trip initiated by the Feeder #3 50-1 ele-ment) after reclosing had occurred. All three feeders supplied by the bus would have

186 7SJ62/63/64 ManualC53000-G1140-C147-1
Automatic Reclosing System (79M)
been cut off from the incoming supply for a fault that should have locked out Feeder#3 only.
To prevent this from happening, zone sequencing is switched on at the bus relay (SeeAR setting dress 7140). With zone sequencing in operation, the bus relay counts thenumber of times a fault is interrupted. For the first fault, the 50-2 element at the bus isallowed to trip. If the fault is at F1 or on Feeder #3, the 50-2 element protecting Feeder#3 will initiate a high speed trip, thus causing the 50-2 element at the bus relay to dropout.
Figure 2-69 Illustration of Zone Sequencing and the Protection of Load Side Fuses
For the second fault, the 50-2 element at the bus relay must be blocked because the50-2 element at Feeder #3 is blocked, and a permanent fault on Feeder #3 could resultin an inadvertent trip by the 50-2 element protecting the bus. Because zone sequenc-ing is switched on at the bus relay, the bus relay counts the number of faults, and afterthe first fault, blocks the 50-2 element from tripping. Therefore, for a permanent faulton Feeder #3, the 50-2 element at the bus would have been blocked after the reclosingattempt, and the 50-1 element at Feeder #3 would have tripped the circuit breaker in0.4 seconds. Had the 50-1 element failed to clear the fault, the 50-1 element at the busrelay, which is set for 0.9 seconds, would serve as backup protection.
For the bus fault F2, the 50-2 element at the bus would have cleared the fault in 0.4seconds. The 50-1 element at the bus serves to backup the 50-2 element. Had zonesequencing not been available, the 50-2 element at the bus relay could not have beenset to clear the bus fault in 0.4 seconds without causing coordination problems be-tween the bus relay and the Feeder #3 relay. On a final note, zone sequencing is onlyeffective at the bus relay when all three feeders utilize high speed tripping prior to thefirst reclosing attempt.

The internal automatic reclosure system will only be effective and accessible if ad-dress 0171 79 Auto Recl. is set to Enabled during configuration or protectivefunctions. If the automatic reclosing function is not required, then address 0171should be set to Disabled. The function can be turned ON or OFF at address 7101FCT 79.
If no automatic reclosures are performed on the feeder for which the 7SJ62/63/64 re-lay is used (e.g. cables, tranformers, motors, etc.), the automatic reclosure function isdisabled by configuration. The automatic reclosure function will then have absolutelyno effect i.e., 7SJ62/63/64 will not process the automatic reclosure function. No mes-sages exist for this purpose and binary inputs for the automatic reclosure function areignored. All parameters of block 71 are inaccessible and insignificant.
Blocking Durationfor Manual-CLOSEDetection
Parameter 7103 BLOCK MC Dur. defines the reaction of the automatic reclosurefunction when a manual closing signal is detected. The parameter can be set to spec-ify how long the auto reclose function will be blocked dynamically in case of an exter-nal manual close-command being detected via binary input (00356 “>Manual Close“). If the setting is 0, the automatic reclosure system will not respond to a man-ual close-signal.
Blocking Time andDynamic Blocking
The blocking time set at address 7105 TIME RESTRAINT defines the time that mustelapse, after a successful reclosing attempt, before the automatic reclosing function isreset, in preparation of a new fault. If a protective element picks up before the blockingtime elapses, the reclosing cycle is continues. If a protective trip occurred after the lastallowable reclosing attempt was made, then together with the trip command the feederis locked out. If a protective element picks up after the blocking time has elapsed, thena new reclosing cycle is initiated.
In general, address 7105 should be set for only a few seconds. In areas with frequentthunderstorms, a shorter blocking time may be necessary to avoid feeder lockout dueto sequential lightning strikes.
A longer blocking time should be chosen if there is no possibility to monitor the circuitbreaker ready status (see below) during multiple reclosing. In this case, the blockingtime should be longer than the time required for the circuit breaker mechanism to beready.
If a dynamic blocking/lock out of the automatic reclosing system was initiated, then re-closing functions remain blocked until the cause of the blocking has been cleared.Subsection 2.13.1 gives further information on this topic, see side title “DynamicBlocking“. The dynamic blocking is associated to the configurable blocking timeSAFETY 79 ready. It is usually started by a blocking condition that has picked up.
Circuit BreakerMonitoring
Reclosing after a short-circuit tripping presupposes that the circuit breaker is ready forat least one TRIP-CLOSE-TRIP cycle at the time when the reclosing function is initi-ated (i.e. at the beginning of a trip command):
The ready-state of the circuit breaker is signalled to the device via the binary input“>CB Ready“ (FNo. 02730).
188 7SJ62/63/64 ManualC53000-G1140-C147-1
Automatic Reclosing System (79M)
− It is possible to check the status of the circuit breaker before each reclosure or todisable this option (address 7113, CHECK CB?):
− CHECK CB? = No check, deactivates the circuit breaker check,
− CHECK CB? = Chk each cycle, to verify the circuit breaker status before eachreclosing command.
− Checking the status of the circuit breaker is usually recommended. Should thebreaker not provide such a signal, you can disable the circuit breaker check at ad-dress 7113 CHECK CB? to No check, as otherwise auto reclosure would be im-possible.
− The status monitoring time CB TIME OUT can be configured at address 7115 if thecircuit breaker check was enabled at address 7113. This time is set slightly higherthan the maximum recovery time of the circuit breaker following reclosure. If the cir-cuit breaker is not ready after the time has expired, reclosing is omitted and dynam-ic blocking is initiated thus locking the auto reclose function.
Time Max. DEAD EXT. serves for monitoring the dead time extension. The extensioncan be initiated by the circuit breaker monitoring time CB TIME OUT and by the syn-chronizing function.
The monitoring time Max. DEAD EXT. is started after the configured dead time haselapsed.
This time must not be shorter than CB TIME OUT. When using the monitoring time CB TIME OUT, the time Max. DEAD EXT. should be set to a value ≥ CB TIME OUT.
If the auto reclose system is operated with a (internal or external) synchronizing func-tion, Max. DEAD EXT. assures that the auto reclose system does not remain in un-defined state when the synchronizing function fails to check back.
If the synchronization is used as synchrocheck (for synchronous systems), the moni-toring time may be configured rather short e.g., to some seconds. In this case the syn-chronizing function merely checks the synchronism of the power systems. If synchro-nism prevails it switches in instantaneously, otherwise it will not.
If the synchronization is used for synchronous/asynchronous networks, the monitoringtime must grant sufficient time for determining the time for switching in. This dependson the frequency slip of the two subnetworks. A monitoring time of 100s should be suf-ficient to account for most applications for asynchronous networks.
Generally, the monitoring time should be longer than the maximum duration of thesynchronization process (parameter 6x12).
The breaker failure monitoring time 7114 T-Start MONITOR determines the timebetween tripping (closing the trip contact) and opening the circuit breaker (checkbackof the CB auxiliary contacts). This time is started each time a tripping operation takesplace. When it has elapsed, the device assumes breaker failure and blocks the autoreclose system dynamically.
Operating Time The operating time monitors the time between pickup and trip command of a protec-tive function configured as starter while the auto reclose system is ready but not yetrunning. A trip command issued by a protective function configured as starter occuringwithin the operating time will start the automatic reclosing function. If this time differsfrom the setting value of T-ACTION (addresse7117), the automatic reclosing systemwill be blocked dynamically.
1897SJ62/63/64 ManualC53000-G1140-C147-1
Functions
The trip time of inverse tripping characteristics is considerably determined by the faultlocation or fault resistance. The operative time prevents reclosing in case of far remotefaults with long tripping time. Trip commands of a protective function that is not con-figured as starter do not affect the operative time.
Number ofReclosing Attempts
The number of reclosing attempts can be set separately for the programs “Phase“ (ad-dress 7136, # OF RECL. PH) and “Ground“ (address 7135, # OF RECL. GND).The exact definition of the programs is described in Subsection 2.13.1 at side title “Re-closing Programs“.
Close Command:Direct or viaControl
Address 7137 Cmd.via control can be set to either generate directly the closecommand via the automatic reclosing function (setting Cmd.via control = none)or have the closing initated by the control function. The setting list for parameter 7137is created dynamically in dependence of the masked switchgear components. If oneof the switchgear components is selected, usually the circuit breaker 52 Breaker,reclosure is accomplished via control. In this case, the automatic reclosing functiondoes not create a close command but issues a close request. This request is forward-ed to the control which then assumes the switching. Thus, the properties defined forthe switchgear component such as interlocking and command times apply for. Hence,it is possible that the close command will not be carried out due to an applying inter-locking condition.
If this behavior is not desired, the auto reclose function can also generate the closecommand “79 Close“ directly which must be marshalled to contact.
Connection toInternalSynchrocheck(only 7SJ64)
The auto reclose function can interact with the internal synchronizing function of the7SJ64 relay. For this purpose, one of the four synchronization groups must be select-ed at address 7138 Internal SYNC thus specifying the synchronization conditionsfor automatic reclosing. Moreover, the close command must be issued via control.Therefore, address 7137 Cmd.via control must be set to select the appropriateswitchgear component, usually the circuit breaker 52 Breaker. Synchronous reclos-ing via the close command “79 Close“ is not possible.
If interaction with the internal synchronization is not desired, address 7138 must beset to none.
Auto Reclosingwith ExternalSynchrocheck
Parameter 7139 External SYNC can be set to determine that the auto reclose func-tion operates with external synchrocheck. External synchronization is possible if theparameter is set to YES and 7SJ64 is linked to the external synchrocheck via the mes-sage 02865 “79 Sync.Request“ and the binary input “>Sync.release“.
2.13.2.2 Configuration
Initiation andBlocking of Reclos-ing by ProtectiveFunctions
At addresses 7150 to 7164 (see table 2-16), reclosing can be initiated or blocked forvarious types of protective elements. They constitute the interconnection between pro-tective elements and auto reclose function. Each address designates a protectivefunction together with its ANSI synonym e.g., 50-2 for the high-set stage of the non-directional time overcurrent protection (address 7152). The setting options have thefollowing meaning:
190 7SJ62/63/64 ManualC53000-G1140-C147-1
Automatic Reclosing System (79M)
− Starts 79 The protective element initiates the automatic reclosure via itstrip command;
− No influence the protective element does not start the automatic reclosure,it may however be initated by other functions;
− Stops 79 the protective element blocks the automatic reclosure, neithercan it be started by other functions; a dynamic blocking is initi-ated.
2.13.2.3 First Reclosing Attempt
Open BreakerTimes
The dead time preceding the first reclosing attempt is set at address 7127 DEADTIME 1: PH for the multiple phase fault reclosing program and at address 7128 DEADTIME 1: G for the single phase fault reclosing program. The time defined by this parameteris started when the circuit breaker opens (if auxiliary contacts are allocated) or whenthe pickup drops out following the trip command of a starter. The exact definition of theprograms is described in Subsection 2.13.1 at “Reclosing Programs“. The dead timeshould be set long enough to allow a temporary fault to clear (0.9 to 1.5 seconds) un-less stability is a concern, in which case faster times may be required (typically 0.3 to0.6 seconds). In radial networks prolonged idle times are usually permitted.
Cyclic Control ofProtectiveFunctions viaAutomaticReclosure
Addresses 7200 to 7211 allow cyclic control of the various protective functions by theautomatic reclosing function. Thus protective stages can be blocked selectively,switched instantaneously or according to the configured delay times. The following op-tions are available:
− Set value T=T The protective stage is delayed as configured i.e., the auto re-close function does not effect this stage;
− instant. T=0 The protective stage becomes instantaneous if the auto re-close function is ready to perform the mentioned cycle;
− blocked T= The protective stage is blocked if the auto reclose functionreaches the cycle defined in the parameter.
2.13.2.4 Second to Fourth Reclosuring Attempt
Open BreakerTimes
If more than one reclosing cycle was set, you can now configure the individual reclos-ing settings for the 2nd to 4th cycle. The same options are available as for the first cy-cle.
For the 2nd cycle:
Address 7129 DEADTIME 2: PH Dead time for the second (2nd) reclosingattempt (multiple phase recl. program)
Address 7130 DEADTIME 2: G Dead time for the second (2nd) reclosingattempt (single phase recl. program)

For the 3rd cycle:
Address 7131 DEADTIME 3: PH Dead time for the second (3rd) reclosingattempt (multiple phase recl. program)
Address 7132 DEADTIME 3: G Dead time for the second (3rd) reclosingattempt (single phase recl. program)
Addresses7224 through 7235 Cyclic control of the various protectivefunctions before the third reclosingattempt
For the 4th cycle:
Address 7133 DEADTIME 4: PH Dead time for the second (4th) reclosingattempt (multiple phase recl. program)
Address 7134 DEADTIME 4: G Dead time for the second (4th) reclosingattempt (single phase recl. program)
Addresses7236 through 7247 Cyclic control of the various protectivefunctions before the fourth reclosuringattempt
2.13.2.5 Fifth to Ninth Reclosing Attempt
If more than four cycles are configured, the dead times preceding the fifth (5th) throughthe ninth (9th) reclosing attempts are equal to the open breaker time which precedesthe fourth (4th) reclosing attempt.
2.13.2.6 Blocking
Blocking Three-Phase Faults
Regardless of which reclosing program is executed, automatic reclosing can beblocked for trips following three-phase faults at address 7165 3Pol.PICKUP BLK.The pickup of all three phases for a specific phase element is the criterion required forthree-phase fault blocking.
Blocking of auto re-close via internalcontrol
The auto reclose function can be blocked, if control commands are issued. The controlinformation must be routed via CFC (interlocking task-level) using theCMD_Information block (see Figure 2-70).

2.13.2.7 Zone Sequencing1)
At address 7140, ZONE SEQ.COORD., the zone sequencing feature can be turned ONor OFF.
If multiple reclosures are performed and the zone sequencing function is deactivated,only those reclosing cycles are counted which the device has conducted after a tripcommand. With the zone sequencing function switched on, an additional sequencecounter also counts such auto reclosures which (in radial systems) are carried out byrelays connected on load side. This presupposes that the pickup of the 50-1/50N-1–stages drops out without a trip command being issued by a protective function initiat-ing the auto reclose function. The parameters at addresses 7200 through 7247 (seeparagraph below at “Initiation and Blocking of Reclosing by Protective Functions“ and“Controlling Directional/Non-Directional Overcurrent Protection Stages via Cold LoadPickup“ can thus be set to determine which protective stages are active or blockedduring what dead time cycles.
In the example shown in Figure 2-69 (Subsection 2.13.1.4), the zone sequencingwould be initated at the bus relay. Moreover, the 50-2 stages would have to be blockedafter the second reclosure i.e., address 7214 bef.2.Cy:50-2 set to blocked T=.The zone sequencing of the feeder relays is switched off but the 50-2 stages must alsobe blocked here after the second reclosing attempt. Moreover, it must be ensured thatthe 50-2 stages start the automatic reclosing function: address 7152 50-2 set toStarts 79.
2.13.2.8 Controlling Directional/Non-Directional Overcurrent Protection Stages via Cold Load Pickup
The cold load pickup function is another possibility to control the protection via the au-tomatic reclosing system (see also Section 2.4). This function provides the address1702 Start Condition. It determines the starting conditions for the increased set-ting values of current and time of the cold load pickup to apply for directional and non-directional overcurrent protection.
If address 1702 Start Condition = 79 ready, the directional and non-directionalovercurrent protection always employ the increased setting values if the automatic re-closing system is ready. The auto reclosing function provides the signal “79 ready”for controlling the cold load pickup. The signal “79 ready“ is always active if the autoreclosing system is available, active, unblocked and ready for another cycle. Controlvia the cold load pickup function is non-cyclic.
Since control via cold load pickup and cyclic control via auto reclosing system can runsimultaneously, the directional and non-directional overcurrent protection must coor-dinate the input values of the two interfaces. In this context the cyclic auto reclosingcontrol has the priority and thus overwrites the release of the cold load pickup function.
If the protective stages are controlled via the automatic reclosing function, changingthe control variables (e.g. by blocking) has no effect on stages that are already run-ning. The stages in question are continued.

Fault Location
2.14 Fault Location
Measurement of the distance to a short-circuit fault is an important feature of the7SJ62/63/64 relay allowing faster determination of the fault location. Fault location isonly possible if the device is connected to both current and voltage transformers.
2.14.1 Description of Fault Location
Initiation Fault location is initiated if the directional or non-directional overcurrent relay elementshave initiated a trip signal. Once initiated, the fault locator determines the valid mea-surement loop and measurement window. Sampled pairs of values of short circuit cur-rent and short circuit voltage, are stored in a buffer, and made available for the imped-ance calculations R (Resistance) and X (Reactance). Measurement quantity filteringand the number of impedance calculations automatically adjust to the number of rele-vant measurement value pairs stored in the buffer.
Fault location can also be initiated using a binary input as long as a directional or non-directional overcurrent relay element has picked up. This feature allows fault locationcalculations to proceed even if another protective relay (load side relay, etc.) clearedthe fault, (e.g. the internal time-overcurrent elements did not trip).
MeasurementProcess
The evaluation of the measured quantities takes place after the fault has been hasbeen isolated and cleared. At least three result pairs of R and X are calculated fromthe stored and filtered measured quantities in accordance with the line equations. Iffewer than three pairs of R and X are calculated, then the fault location feature willgenerate no information. Average and standard deviations are calculated from the re-sult pairs. After eliminating “questionable results”, which are recognized via a largevariance from the standard deviation, average values are calculated once again for X.This average is the fault reactance, and is proportional to the fault distance.
Path Selection Using the pickup of the overcurrent time elements (directional or non-directional), thevalid measurement paths for the calculation of fault reactance’s are selected. The faultreactance’s can, of course, only be calculated for phase-to-ground paths if the deviceis connected to three current transformers connected in a grounded-wye configurationand three voltage transformers connected in a grounded-wye configuration.
Table 2-17 shows the assignment of the evaluated paths to the possible pickup sce-narios of the protective elements given that the device is supplied from three voltagetransformers connected in a grounded-wye configuration. If the voltage transformersare connected in an open delta configuration, then Table 2-18 applies. Of course, nophase-to-ground paths can be measured in this case.
In addition, paths are not available for further calculation if one of the two currents ina path are less than 10% of the other current in that path, or if any currents in the pathare less than 10% of the nominal device current.

Fault Location
Result As results of the fault location, the following results are displayed or obtained usingDIGSI® 4:
− One or more short circuit paths from which the fault reactance was derived.
− One or more reactance’s per phase in Ω secondary.
− The fault distances, proportional to the reactance’s, in km or miles of line, convertedon the basis of the line’s predetermined reactance (entered at address 1105 or1106, see Subsection 2.1.6).
Note: The distance result, in miles or kilometers, can only be accurate for homogenousline sections. If the line is made up of several sections with different reactance’s, thenthe reactance derived by the fault location can be evaluated for a separate calculationof the fault distance. For transformers and motors, only the reactance result, not thedistance result, is significant.
2.14.2 Setting The Functional Parameters
General The calculation of fault distance will only take place if address 0180 Fault Locatoris set to Enabled. If the fault locating function is not needed, then address 0180should be set to Disabled.
Initiation Normally the fault location calculation is started when a protective element initiates atrip signal (8001 START = TRIP). However, address 8001 START is set to Pickup,fault location can be initiated just by the pickup of a protective element. Irrespective ofthis fact, calculation of the fault location can be started externally via binary input(FNo. 01106, “>Start Flt. Loc“).

Breaker Failure Protection (50BF)
2.15 Breaker Failure Protection (50BF)
2.15.1 Description of Breaker Failure Protection
General The breaker failure protection function monitors the reaction of a circuit breaker to atrip signal. To determine if the circuit breaker has properly opened in response to a tripsignal, one of the following methods is used to ascertain the status of the circuit break-er:
• The current flow through the circuit breaker.
• The position of a circuit breaker auxiliary contact.
If after a programmable time delay, the circuit breaker has not opened, a breaker fail-ure trip signal issued, and all adjacent circuit breakers that represent sources to thefault can be tripped (see Figure 2-71, as an example).
Figure 2-71 Functional Principle of the Breaker Failure Protection Function
Initiation The breaker failure protection function can be initiated by two different sources:
• Internal protective function of the 7SJ62/63/64,
• External trip signals via binary inputs („>50BF ext SRC“).
For each of the two sources, a unique pickup message is generated, a unique timedelay is initiated, and a unique tripping signal is generated. The setting values forbreaker failure pickup and delay apply to both sources.
Criteria The criteria used to determine if the circuit breaker has operated is selectable andshould depend on the protective function that initiated the breaker failure function. Ifvoltage protection initiated breaker failure protection, fault current may or may not beflowing through the circuit breaker, therefore, current flow through the circuit breakeris not a reliable indication as to whether the circuit breaker operated properly. In thiscase, the position of the breaker auxiliary contact should be used to determine if thecircuit breaker properly operated. For protective functions that operate in response to

Functions
currents (e.g. directional and non-directional overcurrent protection, etc.), both thecurrent flow through the circuit breaker and the position of the circuit breaker auxiliarycontact can be used to determine if the circuit breaker properly operated. However,operation of a circuit breaker auxiliary contact does not always mean that the circuitbreaker successfully cleared the fault current, therefore, the device can be pro-grammed such that only the current flow criterion is used to determine breaker status.
The current criterion is met if at least one of the three phase currents exceeds the cur-rent flow monitoring setting entered at address 0212 BkrClosed I MIN (see Sub-section 2.1.3.4, “Current Flow Monitoring”). This pickup threshold is also used by otherprotective functions.
Evaluation of the circuit breaker auxiliary contact depends on the type of contact(s),and how they are connected to the binary inputs:
• Both “a” and “b” type auxiliary contacts are connected.
• Only an “a” type auxiliary contact is connected.
• Only a “b” type auxiliary contact is connected.
• No auxiliary contact is connected.
The circuit breaker condition can be detected prior to the initiation of a trip signal, de-pending on the configuration of binary inputs and auxiliary contacts. After a trip com-mand has been issued it is the aim to detect whether the circuit breaker is open or inintermediate postion by means of the checkbacks of its auxiliary contacts. This infor-mation can be used to properly operate the breaker failure function.
Logic If breaker failure is initiated, an alarm message is generated (“50BF int Pickup” or“50BF ext Pickup”), and the breaker failure timer is started. Once the time delayelapses, a breaker failure trip signal is issued (“50BF TRIP”). The trip signal can beconfigured to one of the output relays.
Figure 2-72 shows the logic diagram for the breaker failure protection scheme. It ispossible to turn the entire breaker failure protection function on or off, or it can beblocked dynamically via binary inputs.
If one of the criteria (current value, breaker auxiliary contacts) that led to pickup of thebreaker failure scheme is no longer met during the time delay elapses, then breakerfailure timer drops out and no trip signals are issued.
To protect against nuisance tripping due to excessive contact bounce, a stabilizationof the binary inputs for external trip signals takes place. This external signal must bepresent during the entire period of the delay time, otherwise the timer is reset and notripping signal is issued.

2.15.2 Programming Settings
General The breaker failure protection function is only effective and available if address 0170 50BF is set to Enabled. If the breaker failure function is not required, then address0170 should be set to Disabled. The function can be turned ON or OFF under ad-dress 7001 FCT 50BF.
Criteria Address 7004 Chk BRK CONTACT establishes whether or not a breaker auxiliary con-tact is used, via a binary input, to detect the position of a circuit breaker. If address7004 is set to ON, then both the current flow through the circuit breaker and the posi-tion of the circuit breaker auxiliary contact are used to ascertain the position of the cir-cuit breaker. This is important if the current is smaller than the configured currentthreshold (BkrClosed I MIN, address 0212) despite closed circuit breaker. The lat-ter may apply if protective tripping was caused by a voltage measurement (e.g. 59, 27,64). If these protective functions issue a trip command, the criteria for current and aux-iliary contacts are linked by a logical OR operation. Without the auxiliary contact crite-rion the circuit breaker failure protection would not be able to take effect in this case.If address 7004 is set to OFF, only the current flow through the circuit breaker is usedto indicate the position of the circuit breaker.
The current flow monitoring setting programmed at address 0212 BkrClosed I MINapplies to all three phases, and should be selected such that it is at least 10 % belowthe smallest fault current the circuit breaker would interrupt when responding to tripsignals initiated by protective relays. The setting at address 0212 should not be settoo low, otherwise, the danger exists that equalization processes in the current trans-former secondary circuit could lead to extended drop out times under conditions of ex-tremely high current to be switched off. In addition, it should be noted that other pro-tection functions depend on the current flow monitoring settings as well (e.g. voltageprotection, overload protection, and restarting block for motors).
Time Delay The breaker failure time delay setting is entered at address 7005 TRIP-Timer. Thissetting should be based on the circuit breaker interrupting time plus the dropout timeof the current flow monitoring element plus a safety margin. Figure 2-73 illustrates thetiming of a typical breaker failure scenario.

2.16 Synchronism and Voltage Check (7SJ64 only)
2.16.1 Functional Description
General When connecting two components of a power system, the synchronizing feature ver-ifies that the start does not endanger the stabilty of the power system. Typical appli-cations are for example the synchronization of a feeder and a busbar (see Figure 2-74) or the synchronization of two busbar sections via bus coupler (see Figure 2-75).
The configuration decides whether the synchronism check is carried out only for auto-matic reclosing or only for circuit breaker control or both. It is also possible to specifydifferent release criteria for automatic close or control close. Synchronous connectionis always accomplished via the integrated control.
For comparing the two voltages the synchronizing functions takes the reference volt-age V1 and an additional voltage to be connected U2. The reference voltage U1 is con-nected to the multi-phase system. The voltage to be synchronized U2 is assigned tothe single-phase connection and may be any phase-ground or phase-phase voltage.
Figure 2-74 Infeed
If a transformer is switched between the two VT’s (Figure 2-74), its vector group canbe adapted in the 7SJ64 relay so that external adaptors are not required.
The synchronizing feature of 7SJ64 usually cooperates with the integrated automaticreclosing system and the control function. It is also possible to employ an external au-tomatic reclosing system. In such a case signal exchange between the devices is ac-complished via binary inputs and outputs.

Operating Modes The synchronizing function can be operated in two modes:
• Synchrocheck
• Synchron/Asynchron
Synchronous power systems exhibit small differences regarding phase angle and volt-age modulus. The operating time of the circuit breaker doesn’t have to be taken intoaccount. The SYNCHROCHECK mode is used which corresponds to the classic synch-rocheck function.
To the contrary, asynchronous systems include bigger differences and the time win-dow for switching on is passed more quickly. It is reasonable to consider the operatingtime of the circuit breaker. The ASYN/SYNCHRON mode is used.
FunctionalSequence
The synchronizing function only opperates if it receives a measurement request. Thisrequest may be issued by the control, the automatic reclosing function or externallyvia binary input e.g., from an external automatic reclosing system.
The measurement request initiates the measurement (message “25x meas.“; withx = 1..4, according to the function group). Depending on the selected operating mode,the configured release conditions are then checked (see side titles “Synchrocheck“ /„Synchronous/ Asynchronous“).
Each condition is indicated explicitely ( messages “25 Vdiff ok“, “25 fdiff ok“,“25 adiff ok“); also those conditions that are not fulfilled if, for example, voltagedifferences (messages “25 V2>V1”, “25 V2<V1”), frequency differences (messages“25 f2>f1”, “25 f2<f1”) or angle differences (messages “25 a2>a1”, “25 a2<a1”) areoutside the threshold values. For these messages to be sent, both voltages must liewithin the operating range of the synchronizing function (see side title “OperatingRange”).
These conditions met, the synchronizing function issues a release signal for closingthe relay (“25 CloseRelease“). This release signal is generally processed by the

Functions
control which issues the actual close command for controlling the circuit breaker (seealso side title “Interaction with the Control”).
Measuring the synchronism conditions can be confined to the a maximum monitoringtime T-SYN. DURATION. If the conditions are not fulfilled during T-SYN. DURATION,the release is cancelled (message “25 MonTimeExc“). A new synchronization canonly be performed if a new measurement request is received.
Operating Range The operating range of the synchronizing function is defined by the configured voltagethresholds Vmin and Vmax, and the fixed frequency band fN ± 3 Hz.
If measurement is started and one or both voltages are outside the operating range,or one voltage leaves the permissible range, corresponding messages indicate thisbehavior (“25 f1>>“, “25 f1<<“, “25 V1>>“, “25 V1<<“, etc.).
Synchrocheck Synchrocheck verifies the synchronism before connecting the two system compo-nents and cancels the connecting process if parameters for synchronism lie outsidethe configured thresholds.
Before a release is granted, the following conditions are checked:
− Is the reference voltage V1 above the value Vmin but below the maximum voltageVmax?
− Is the voltage V2 to be synchronized above the setting value Vmin but below themaximum voltage Vmax?
− Is the voltage difference V2 – V1 within the permitted threshold dV ASYN V2>V1?
− Is the voltage difference V1 – V2 within the permitted threshold dV ASYN V2<V1?
− Are the two frequencies f1 and f2 within the permitted operating range fN ± 3 Hz?
− Is the frequency difference f2 – f1 within the permitted threshold df ASYN f2>f1?
− Is the frequency difference f1 – f2 within the permitted threshold df ASYN f2<f1?
− Is the angle difference ϕ2 – ϕ1 within the permitted threshold da SYNC a2> a1?
− Is the angle difference ϕ1 – ϕ2 within the permitted thresholdda SYNC a2< a1?
Synchronous/Asynchronous
The operating mode “Synchronous/Asynchronous“ uses the frequency slip of the twopower systems (parameter F SYNCHRON) to determine whether the to power systemsare asynchronous to each other (“Switching under Asynchronous System Conditions“)or synchronous (“Switching under Synchronous System Conditions“). If they are asyn-chronous, the time window for switching is passed relatively quickly. Therefore, it isreasonable to take into account the operating time of the circuit breaker. Thus the de-vice can issue the On command at a time where asynchronous conditions prevail.When the poles make contact the conditions will be synchronous.
It is thus possible to generally account for the operating time of the circuit breaker i.e.,also with synchronous conditions prevailing.
Switching underSynchronous Sys-tem Conditions
Switching under synchronous conditions means that the On command will be releasedas soon as the characteristic data (voltage difference, angle difference) are within thethresholds specified by configuration.

− Is the voltage V2 to be synchronized above the setting value Vmin but below themaximum voltage Vmax?
− Is the voltage difference V2 – V1 within the permitted threshold dV ASYN V2>V1?
− Is the voltage difference V1 – V2 within the permitted threshold dV ASYN V2<V1?
− Are the two frequencies f1 and f2 within the permitted operating range fN ± 3 Hz?
− Is the frequency difference smaller than the configured threshold frequency differ-ence F SYNCHRON which defines the transition from synchronous to asynchronoussystems.
− Is the angle difference ϕ2 – ϕ1 within the permitted threshold da SYNC a2> a1?
− Is the angle difference ϕ1 – ϕ2 within the permitted threshold da SYNC a2< a1?
All synchronism conditions fulfilled, the message “25 Synchron” is issued.
Switching underAsynchronousSystem Conditions
For switching under asynchronous system conditions the device determines the timefor issuing the On command from the angle difference and the frequency differencesuch that the voltages (of busbar and feeder) are identical the instant the poles makecontact. For this purpose the device must be informed on the operating time of the cir-cuit breaker for closing.
Before granting a release for closing, the following conditions are checked:
− Is the reference voltage V1 above the setting value Vmin but below the maximumvoltage Vmax?
− Is the voltage V2 to be synchronized above the setting value Vmin but below themaximum voltage Vmax?
− Is the voltage difference V2 – V1 within the permitted threshold dV ASYN V2>V1?
− Is the voltage difference V1 – V2 within the permitted threshold dV ASYN V2<V1?
− Are the two frequencies f1 and f2 within the permitted operating range fN ± 3 Hz?
− Is the frequeny difference f2 – f1 within the permitted threshold df ASYN f2>f1?
− Is the frequeny difference f1 – f2 within the permitted threshold df ASYN f2<f1?
When the check has been terminated successfully, the device determines the nextsynchronizing time from the angle difference and the frequency difference. The Oncommand is issued at synchronization time minus operating time of the circuit breaker.
De-energizedSwitching
Connecting two components of a power system is also possible if at least one of thecomponents is de-energized. Besides release under synchronous conditions, the fol-lowing additional release conditions can be selected for the check:
− SYNC V1>V2< = Release of the condition that component V1 is energizedand component V2 is de-energized.
− SYNC V1<V2> = Release of the condition stating that component V1 is de-energized and component V2 is energized.
2137SJ62/63/64 ManualC53000-G1140-C147-1
Functions
− SYNC V1<V2< = Release of the condition stating that component V1 andcomponent V2 are de-energized.
Each of these conditions can be enabled or disabled individually; combinations arealso possible (e.g., release if SYNC V1>V2< or SYNC V1<V2> are fulfilled).
The release conditions can be configured individually either for automatic reclosing orfor manual closing. You can for example allow manual closing for synchronism or forde-energized feeder whereas before an automatic reclosing operation, checking onlyde-energized conditions at one feeder terminal and afterwards only synchronism atthe other.
The threshold below which a power system component is considered as de-energizedis defined by parameter V<. If the measured voltage exceeds the threshold V>, it isenergized.
Before granting a release for connecting the energized component V1 and the off-cir-cuit component V2, the following conditions are checked:
− Is the reference voltage V1 above thesetting value Vmin and V> but below the max-imum voltage Vmax?
− Is the voltage to be synchronized V2 below the threshold V<?
− Is the frequeny f1 within the permitted operating range fN ± 3 Hz?
After successful termination of the check the release is granted.
Switching the de-energized component 1 to the energized component 2 or connectingthe de-energized component 1 to the equally de-energized component 2 the condi-tions to be fulfilled are the same.
The associated messages indicating the release via the corresponding condition areas follows: “25 V1< V2>”, “25 V1> V2<” and “25 V1< V2<”.
Via binary input “>25 V1>V2<”, “>25 V1<V2>” and “>25 V1<V2<” release condi-tions can be issued externally provided the synchronization is controlled externally.
Parameter TSUP VOLTAGE (address 6x11A) can be set to configure a monitoring timewhich requires above stated release conditions to be at least fulfilled for de-energizedconnection before switching is allowed.
Direct Command/Blocking
Parameter Direct CO can be set to grant a release without performing any checks.In this case switching is released by activating the allocated binary input “>25direct CO”. It is obviously not reasonable to combine Direct CO with other release condi-tions.
Blocking the entire synchronizing function is possible via the binary input “>BLK 25 CLOSE”. This status is indicated via “25 CLOSE BLK”.
SYNC FunctionGroups
The 7SJ64 relay comprises 4 synchronizing function groups (Function group 1 to 4)which each contain all setting parameters for one synchronizer. This includes theswitchgear component for which the synchronization settings are to be applied. If noswitchgear component is unambiguously identified here, the synchronizing functionmay be used as external synchronizing feature which must be triggered by binary in-put messages. Allocation of switchgear component and function group is accom-plished using one of the binary inputs “>25-1 act” to “>25-4 act”.
214 7SJ62/63/64 ManualC53000-G1140-C147-1
Synchronism and Voltage Check (7SJ64 only)
Selecting one SYNC function group several times, causes output of error message(“25 FG-Error”).
Interaction with theControl
Basically, the synchronizing feature interacts with the device control. The switchgearcomponent to be synchronized is selected via a parameter. If an On-command is is-sued, the control accounts for the fact that the switchgear component requires syn-chronization. The control sends a measurement request (“>25 Measu. Only”) to thesynchronizing function which is then started. Having completed the check, the syn-chronizing function issues the release message (“25 CloseRelease“) to which thecontrol responds by terminating the switching operation positively or negatively (seeFigure 2-76).
Figure 2-76 Interaction of control and synchronizing function
Interaction withAutomaticReclosing
IThe automatic reclosing function can also interact with the synchronizing function.They are linked via the device control. The selection is made via parameters of the au-tomatic reclosing function. Thereby you can determine which switch is activated andwhich function group (FG) is used. If no function group is entered, the close commandof the auto reclose function is carried out in unsychronized form. Equally, the com-mand “79 Close” (message 02851) allows only unsynchronized switching.
If the circuit breaker Q0 is configured as switching component, a close command ofthe automatic reclosing function will address this breaker and assign it a close com-mand which will be processed by the control. As this breaker requires synchronization,the control launches the synchronizing function and awaits release. The configuredconditions fulfilled, the release is granted and the control issues the close command(see Figure 2-77).

Interaction withExternal Control
As another option the synchronizing function can be activated via external measure-ment request. The synchronizing function can be started via binary input using a mea-surement request (“>25 Measu. Only” or “>25 Start” and “>25 Stop”).
After the synchronizing function has completed the check, issues a release message(“25 CloseRelease“, see Figure 2-78).

− value of the reference voltage V1
− value of the voltage to be synchronized V2
− Frequency values f1 and f2
− Differences of voltage, frequency and angle.
The models featuring a four-line display have a preset default display which shows theabove mentioned measured values comprised on one display (see Figure A-75 of theAppendix A.4.5).
2.16.2 Functional Settings
General The synchronizing function is only included in the 7SJ64 relay with its 4 voltage inputs.
While setting the power system data (see Subsection 2.1.3) the device was alreadyprovided with data relevant for the measured values and the operating principle of thesynchronizing function. This concerns the following parameters:
0202 Vnom PRIMARY primary nominal voltage of the voltage transformers V1(phase-to-phase) in kV;
0203 Vnom SECONDARY secondary nominal voltage of the voltage transformersV1 (phase-to-phase) in V;
0213 VT Connection determines how voltage transformers are connected;
0214 Rated Frequency the operating range of the synchronizing function refersto the rated frequency of the power system (fN ± 3 Hz);
The synchronizing function can only operate if enabled under at least one of the ad-dresses 0161 25 Function 1 through 0164 25 Function 4 during configura-tion of the functional scope (see Subsection 2.1.1). The operating mode can be pre-selected: ASYN/SYNCHRON means that switching will take place under synchronousand asynchronous conditions. SYNCHROCHECK corresponds to the classic synchro-check function. If not required, this function is set to Disabled. A synchronizing func-tion group thus rendered ineffective is hidden at the menu item Synchronization,all others are shown.
Only the corresponding messages of Function Group 1 are pre-allocated for IEC60870–5–103 (VDEW). If other function groups (2 to 4) are configured and if their mes-sages are to be disposed of via VDEW, the must first be configured to the the systeminterface.
Selecting one of the displayed SYNC function groups in DIGSI® 4 opens a dialog boxwith the tabs “General”, “Power System Data”, “Asynchronous Conditions”, “Synchro-nous Conditions” and “Synchrocheck” in which the individual settings for synchroniza-tion can be made. For SYNC function group x the following holds:
2.16.2.1 General Settings
The general thresholds for the synchronizing function are set at addresses 6x01through 6x12.
2177SJ62/63/64 ManualC53000-G1140-C147-1
Functions
Address 6x01 Synchronizing X can be set to switch the entire synchronous func-tion group x ON or OFF. If switched off, the synchronous check does not verify the syn-chronizing conditions and release is not granted.
Address 6x02 SyncCB is used to select the switchgear component to which the syn-chronizing settings will be applied. Select the option none to use the function as ex-ternal synchronizing feature. It will then be triggered via binary input messages.
Addresses 6x03 Vmin and 6x04 Vmax set the upper and lower limits for the requestband for voltages V1 or V2 and thus determine the operating range for the synchro-nizing function. If the values leave this band, a message will be output.
Address 6x05 V< indicates the voltage threshold below which the feeder or the bus-bar can safely be considered switched off (for checking a de-energized feeder or bus-bar).
Address 6x06 V> indicates the voltage threshold above which the feeder or busbarcan safely be considered energized (for checking an energized feeder or busbar). Itmust be set below the anticipated operational undervoltage.
The setting for the mentioned voltage values is made secondary in volts. When usingthe PC and DIGSI® 4 for configuration, these values can also be entered as primaryvalues. Depending on the connection of the voltages these are phase-ground voltagesor phase-phase voltages.
Addresses 6x07 to 6x10 are set to specify the release conditions for the closingcheck:
6x07 SYNC V1<V2> = Component V1 must be de-energized, componentV2 must be energized (connection to reference withoutvoltage, dead line);
6x08 SYNC V1>V2< = Component V1 must be energized, componentV2 must be de-energized (connection to feeder withoutvoltage, dead bus);
6x09 SYNC V1<V2< = Both V1 and V2 must be without voltage (connectionreference and feeder without voltage, dead bus/deadbus);
6x10A Direct CO = Command is released without checks.
The possible release conditions are independent of each other and can be combined.
Parameter TSUP VOLTAGE (address 6x11A) can be used to set a monitoring timewhich requires above mentioned additional release conditions to be fulfilled at leastbefore release is granted for switching without voltage The preset value of 0.1 s ac-counts for transient responses and can be applied without modification.
Release via synchronous check can be limited to a configurable synchronous moni-toring time T-SYN. DURATION (address 6x12). The configured conditions must befulfilled within this time or release is not granted and the synchronizing function isshed. If this time is set to ∞, the conditions will be checked until they are fulfilled.

Synchronism and Voltage Check (7SJ64 only)
2.16.2.2 Power System Data
The power system data for the synchronizing function are set at addresses 6x20through 6x25.
The circuit breaker closing time T-CB close at address 6x20 is required if the deviceis to close also under asynchronous system conditions, no matter whether for manualclosing, for automatic reclosing after three-pole tripping, or for both. The device willthen calculate the time for the close command such that the voltages are synchronousthe instant the breaker poles make contact. Please note this includes the operatingtime of the breaker and also the pickup time of an auxiliary relay that may be connect-ed on line side.
The parameter Balancing V1/V2 (adress 6x21) can be set to account for differentCT ratios of the two parts of the power system (see example in Figure 2-79).
If a transformer is located between the system parts to be synchronized, its vectorgroup can be accounted for by angle adjustment so that no external adjusting mea-sures are required. Parameter ANGLE ADJUSTM. (address 6x22A) is used to thisend.
• The phase angle from V1 to V2 is evaluated positively.
Example (see also Figure 2-79):Busbar 400 kV primary
100 VsecondaryFeeder 220 kVprimary
110 VsecondaryTransformer 400 kV/220 kV
Vector group Dy(n) 5The transformer vector group is defined from the high side to the low side. In the ex-ample, the reference voltage transformers (V1) are the ones of the transformer highside of i.e., the angle 5 x 30° (according to vector group) that is 150°:Address 6x22A: ANGLE ADJUSTM. = 150°.
The reference voltage transformers supply 100 V secondary for primary operation atnominal value while the feeder transformer supplies 110 V secondary. Therefore, thisdifference must be balanced:Address 6x21: Balancing V1/V2 = 100 V/110 V = 0.91.

Figure 2-79 Busbar voltage measured via transformer
Connections 7SJ64 provides three voltage inputs for connection of the voltage V1 and one voltageinput for voltage V2 (see Figure 2-80 and Figure 2-79). According to definition, thethree-phase voltage is the reference voltage V1. To compare the three-phase voltageV1 and the voltage V2 correctly with each other, the device must be informed on theconnection type of the voltage V2. Address CONNECTIONof V2 assumes this task(parameter 6x23).

For the device to perform the internal conversion to primary values, the primary ratedtransformer voltage of the measured quantity V2 must be entered via parameter 6x25 VT Vn2, primary if a transformer is located between the system parts to be syn-chronized.

2.16.2.3 Asynchronous Conditions
The synchronizing function 7SJ64 can issue a close command also for asynchronouspower systems such that, considering the circuit breaker operating time (address6x20), the power systems are coupled when the phases are equal.
Parameters 6x30 dV ASYN V2>V1 and 6x31 dV ASYN V2<V1 can be set to adjustthe permissible voltage differences asymmetrically.
Parameters 6x32 df ASYN f2>f1 and 6x33 df ASYN f2<f1 limit the operatingrange for asynchronous switching. These two parameters enable an asymmetricalswitching range to be set.
2.16.2.4 Synchronous Conditions
Address 6x40 SYNC PERMIS. activates or deactivate the connection under synchro-nous system conditions (YES) or (NO).
Address 6x41 F SYNCHRON is an automatic threshold between synchronous andasynchronous switching. If the frequency difference is below the specified threshold,the power systems are considered synchronous and the conditions for synchronousswitching apply. If it is above the threshold, the switching is asynchronous and the an-ticipated in-phase time is calculated.
Address 6x42 dV SYNC V2>V1 and 6x43 dV SYNC V2<V1 can be used to set thepermissible voltage differences asymmetrically.
Address 6x44 da SYNC a2> a1 and 6x45 da SYNC a2< a1 confine the operatingrange for synchronous switching. These two parameters allow an asymmetricalswitching range to be configured (see Figure 2-81).
Moreover, the release time delay T SYNC-DELAY (address 6x46) can be set for whichall synchronous conditions must at least be fulfilled for the closing command to be gen-erated after expiration of this time.

Up to two temperature detection units (RTD-boxes) with 12 measuring sensors in totalcan be applied for temperature detection and are recognized by the device. In partic-ular they enable the thermal status of motors, generators and transformers to be mon-itored. Rotating machines are additionally monitored for a violation of the bearing tem-perature thresolds. The temperatures are measured in different locations of the pro-tected object by employing temperature sensors (RTD = Resistance Temperature De-tector) and are transmitted to the device via one or two RTD-boxes 7XV566.
Interaction with theOverloadProtection
The ambient temperature or coolant temperature can be transmitted to the overloadprotection of the device via the RTD-box. The temperature detector required for thispurpose must be connected to the detector input 1 of the first RTD-box (correspondsto RTD 1).
2.17.1 Functional Description
RTD-box 7XV56 The RTD-box 7XV566 is an external unit which is mounted on the top-hat rail. It fea-tures 6 temperature detectors and one RS485 interface for communication with theprotection device. The RTD-box detects the coolant temperature of each measuringpoint from the resistance value of the temperature detectors (Pt100, Ni100 or Ni120)connected via a two- or three-wire lines and converts it to a digital value. The digitalvalues are held available at a serial port.
Communicationwith the ProtectionDevice
The protection device can employ up to two RTD-boxes via its service port (port C),7SJ64 also via the additional port (port D).
A maximum of 12 temperature detectors is thus available. For greater distances to theprotection device the communication via fibre optic cables is recommend. Possiblecommunication structures are shown in Appendix A.3.4.
ProcessingTemperatures
The transmitted non-linearized temperature values are converted to a temperature indegree Celsius or Fahrenheit. The conversion depends on the temperature sensorused.
For each temperature detector two thresholds decision can be performed which areavailable for further processing. The user can make the corresponding allocations inthe configuration matrix.
An alarm is issued for each temperature sensor in the event of a short-circuit or inter-ruption in the sensor circuit.
Figure 2-83 shows the logic diagram of the temperature processing.
The manual supplied with the RTD-box contains a connections diagram and dimen-sioned drawing.

2.17.2 Configuration Notes
General Temperature detection is only effective and accessible if this function was allocated toan interface during configuration of the protective functions (Subsection 2.1.1). At ad-dress 0190 RTD-BOX INPUT the RTD-box(es) is allocated to the interface at whichit will be operated (e.g. port C). The number of sensor inputs and the communicationmode were set at address 0191 RTD CONNECTION. The temperature unit (°C or °F)was set in the Power System Data 1 at address 0276 TEMP. UNIT.
Device Settings The settings are the same for each input and are here shown at the example of mea-suring input 1.
Set the type of temperature detector for RTD1 (temperature sensor for measuringpoint 1) at address 9011A RTD 1 TYPE. You can choose between Pt 100 W, Ni 120 W and Ni 100 W. If no temperature detector is available for RTD1, set RTD 1 TYPE = Not connected. This setting is only possible via DIGSI® 4 at “AdditionalSettings“.

Functions
The mounting location of RTD1 is set at address 9012A RTD 1 LOCATION. You canchoose between Oil, Ambient, Winding, Bearing and Other. This setting is onlypossible via DIGSI® 4 at “Additional Settings“.
Furthermore, you can set an alarm temperature and a tripping temperature. Depend-ingn on the temperature unit selected in Power System Data (section below address0276 TEMP. UNIT), you can enter the alarm temperature at address 9013 RTD 1 STAGE 1 in degree Celsius (°C) or in degree Fahrenheit (°F) at address 9014 RTD 1 STAGE 1. The tripping temperature is set at address 9015 RTD 1 STAGE 2 indegree Celsius (°C) or degree Fahrenheit (°F) at address 9016 RTD 1 STAGE 2.
The settings for the all other connected temperature detectors are made accordingly(see Settings 2.17.2.1).
RTD-boxSettings
If temperature detectors are used with two-wire connection, the line resistance (forshort-circuited temperature detector) must be measured and adjusted. For this pur-pose, select mode 6 in the RTD-box and enter the resistance value for the correspond-ing temperature detector (range 0 to 50.6 Ω). If a 3-wire connection is used, no furthersettings are required to this end.
A baudrate of 9600 bits/s ensures communication. Parity is even. The factory settingof the bus number 0. Modifications at the RTD-box can be made in mode 7. The fol-lowing convention applies:
Further information is provided in the operating manual of the RTD-box.
ProcessingMeasured Valuesand Messages
The RTD-box is visible in DIGSI® 4 as part of the 7SJ62/63/64 relays i.e., messagesand measured values are displayed in the configuration matrix besides the internalfunctions and like them they can be masked and processed. Messages and measuredvalues can thus be forwarded to the integrated user-defined logic (CFC) and intercon-nected as desired.
If it is desired that a message should appear in the event buffer, a cross must be en-tered in the intersecting box of column/row.

Phase Rotation
2.18 Phase Rotation
2.18.1 Description of Phase Rotation
General Various functions of the 7SJ62/63/64 only function correctly if the phase rotation of thevoltages and currents is known. Among these functions are negative sequence pro-tection, undervoltage protection (based only on positive sequence voltages), direc-tional overcurrent protection, and measurement quantity monitors. A phase rotation isimplemented in the 7SJ62/63/64 device using binary inputs and settings, thus makingit possible for all protective and monitoring functions to operate correctly when thephase rotation is reversed.
If an “acb” phase rotationphase rotation is normal, the appropriate setting should beentered at address 0209. (See Subsection 2.1.3).
If the phase rotation can change during operation (e.g. the direction of a motor mustbe routinely changed), then a changeover signal at the input masked for this purposeis sufficient to inform the protective relay of the phase rotation changeover.
Logic As stated before, the phase rotation is always established at address 0209 PHASE SEQ.. The binary input (FNo. 05145, “>Reverse Rot.”) sets the phase rotation forthe opposite of the setting at 0209, via the exclusive-OR function (see Figure 2-84).
Figure 2-84 Message Logic for the phase rotation Changeover
Influence on Pro-tective Functions
The swapping of phases directly impacts the calculation of positive and negative se-quence quantities, as well as phase-to-phase voltages via the subtraction of onephase-to-ground voltage from another. Therefore, this function is vital so that phasedetection messages, fault values, and operating measurement values are not falsified.As stated before, this function influences the negative sequence protection function,directional overcurrent protection function, and some of the monitoring functions (seeSubsection 2.10.1.3) that issue messages if the required and calculated phase rota-tions do not match.
2.18.2 Programming Settings
The normal phase sequence is set at 0209 PHASE SEQ. (see Subsection 2.1.3).If, on the system side, phase rotation are made temporarily, then these are communi-cated to the protective device using the binary input “>Reverse Rot.”, FNo. 05145.

2.19 Protection Function Logic
The function logic is the heart of the device. It coordinates the sequence of both theprotective and auxiliary functions, processes functional decisions, and processes datareceived from the system. In particular, the function logic is responsible for the follow-ing:
• Processing Measurement and Detection Logic
• Processing Tripping Logic
2.19.1 Pickup Logic for the Entire Device
General DevicePickup andDropout
The pickup signals for all protective functions in the device are connected via an “OR”function, and lead to the general device pickup. General device pickup is initiated bythe first function to pickup, and general device drop out occurs when the last functiondrops out. A corresponding message indicating that general device pickup has oc-curred is reported.
General device pickup is a precondition for a series of internal and external functionsthat occur subsequently. The following are among the internal functions controlled bygeneral device pickup:
• Start of Trip Log: From general device pickup to general device drop out, all faultmessages are entered in the trip log.
• Initialization of Oscillographic Records: The storage and maintenance of oscillo-graphic values can also be made dependent on the general device pickup.
External functions can be controlled by general device pickup, using an output con-tact. Examples are:
• Restarting devices
• Starting of additional devices, or similar
2.19.2 Tripping Logic of the Entire Device
2.19.2.1 Description
General Trip The tripping signals for all protective functions are connected by “OR” and generate amessage indicating that the device has initiated a trip signal.
This message can be configured to an LED or binary output, just as the individual trip-ping messages can.
Terminating theTripping Signal
• All trip signals from a protection function hold the 00511 “Relay TRIP” function,and start the minimum trip signal duration timer (set at address 210A TMin TRIP CMD, see Figure 2-85). This trip signal duration timer ensures the trip signal is trans-

Protection Function Logic
mitted to the circuit breaker for a sufficient amount of time, even if the function whichissued the trip signal drops out quickly. The trip signal is only terminated after allprotection functions drop out AND the minimum trip signal duration expires.
• Finally, it is possible to latch the trip signal until it is manually reset (lockout func-tion). The reset takes place either by pressing the LED reset key or by activating anappropriately masked binary input. A precondition, of course, is that the circuitbreaker trip coil – as usual – remains energized at the circuit breaker as long as thetrip signal is present, and that the trip coil current is interrupted by the auxiliary con-tacts of the circuit breaker.

2.19.2.2 Programming Settings for Tripping Logic
Trip Signal Dura-tion
The setting of the minimum trip signal duration at address 0210A TMin TRIP CMDwas already discussed in Subsection 2.1.3. This time is valid for all protective func-tions that can initiate trip signals, as well as for trip signals that are initiated using thedevice function controller.
2.19.3 Statistical Counters
2.19.3.1 Description
Number of Trips The number of trips initiated by the 7SJ62/63/64 is counted, as long as the position ofthe circuit breaker is monitored via breaker auxiliary contacts and binary inputs. Forthis purpose it is necessary to allocate the internal pulse counter “Number of TRIPs“to a binary input in the configuration matrix which is controlled by the TRIP position ofthe circuit breaker. The pulse count “Number of TRIPs“ can be found in the “Statistics“

Number ofAutomaticReclosingCommands
The number of reclosing commands initiated by the automatic reclosing function issummed up in separate counters for the 1st and ≥ 2nd cycle.
Fault Current Furthermore, the fault current in each pole of the circuit breaker is determined for eachtrip signal. The fault current is indicated in the fault messages and is added to previ-ously stored fault current values in the statistic-counters to maintain an accumulationof fault currents, per pole, experienced by the breaker over time.
Operating hours The operating hours under load are also stored (the current value in at least one phaseis larger than the limit value set under address 0212 BkrClosed I MIN). Thecounter and memory levels are secured against loss of auxiliary voltage.

Important events and conditions are displayed, using LEDs on the front panel of therelay. The relay also contains output relays for remote signaling. All LEDs and binaryoutputs indicating specific messages can be freely configured. The relay is deliveredwith a default setting. The SIPROTEC® 4 System Manual gives a detailed descriptionof the configuration procedure. The Appendix of this manual deals in detail with thedelivery status and the allocation options.
The output relays and the LEDs can be operated in a latched or unlatched mode (in-dividually settable for each one).
The latched conditions are protected against loss of the auxiliary voltage. They are re-established after restart of the device. However they can be reset as follows:
− On site by pressing the LED key on the relay.
− Remotely using a binary input configured for that purpose.
− Using one of the serial interfaces.
− Automatically at the beginning of a new pickup.
Condition messages should not be stored. Also, they cannot be reset until the criterionto be reported is cleared. This applies to messages from monitoring functions, or sim-ilar.
A green LED (“RUN”) displays operational readiness of the relay, and cannot be reset.It goes out if the self-check feature of the microprocessor recognizes an abnormal oc-currence, or if the auxiliary voltage is lost.
When auxiliary voltage is present, but the relay has an internal malfunction, then thered LED (“ERROR”) lights up and the processor blocks the relay.

Fault InformationDisplay or PersonalComputer
Events and conditions can be read out on the display on the front cover of the relay.Using the front PC interface or the rear service interface, a personal computer can beconnected, to which the information can be sent.
The relay is equipped with several event buffers, for operational messages, circuitbreaker statistics, etc., which are protected against loss of the auxiliary voltage by abuffer battery. These messages can be retrieved, at any time, using the operating key-pad in the display field, or transferred to a personal computer, using the serial operat-ing interface. Readout of messages during operation is described in detail in theSIPROTEC® 4–System Manual.
Division ofMessages
The messages are categorized as follows:
• Event Log: These are message that can occur during the operation of the device.They include information about the status of device functions, measurement data,system data, recording of control commands, and similar information.
• Trip Log: Fault messages are message from the last 8 network faults that were pro-cessed by the device.
• Sensitive Ground Fault Log: Ground fault messages, if the device has sensitiveground fault detection.
• Statistics: These values include a counter for the trip commands initiated by the de-vice, accumulated currents interrupted by the individual poles of the circuit breaker,and the operating hours of the network or equipment being protected.
A complete list of all message and output functions that can be generated by the de-vice, with the associated information number (FNo), can be found in the Appendix.The lists also indicate where each message can be sent. The lists are based on aSIPROTEC® 4 device with the maximum number of functions. If functions are notpresent in the specific version of the device, or if they are set as “Disabled” in DeviceConfiguration, then the associated messages cannot appear.
2.20.1.1 Event Log (Operating messages)
The Event Log contains operating messages that the device generates during opera-tion. All operating messages are stored in the Annunciation Logs. Up to 200 operat-ing messages are recorded in chronological order in the device. New messages areadded at the end of the list. If the memory has been exceeded, then the oldest mes-sage is written-over for each new message.
2.20.1.2 Trip Log (Fault messages)
After a short-circuit fault on the system, for example, important information about theprogression of the fault can be retrieved, such as the pickup of a protective element orthe initiation of a trip signal. The time the initial occurrence of the short-circuit fault oc-curred is accurately provided via the system clock. Time progression of the short-cir-cuit fault is reported based on the moment of pickup, so that the duration, until the tripsignal is issued and interrupted, is available. The time resolution used for reporting is1 ms.

Spontaneousmessages
The spontaneous messages that can be viewed on the device front serve to displaythe most important data about a fault. For devices featuring a four-line text display themessages appear automatically in the display, after a general pickup of the device, inthe sequence shown in Figure 2-86.
If the device features a grahpical display, these messages will only occur if spontane-ous fault messages were set at address 0611 unlike the default setting.
Figure 2-86 Display of Spontaneous Messages in the HMI – Example
Retrievedmessages
The messages for the last eight network faults can be retrieved. The definition of a net-work fault is such that the time period from fault detection up to final clearing of thedisturbance is considered to be one network fault. If auto-reclosing occurs, then thenetwork fault ends after the last reclosing shot, which means after a successful reclos-ing or lockout. Therefore the entire clearing process, including all reclosing shots, oc-cupies only one fault record. Within a network fault, several indications can occur(from the first pickup of a protective function to the last dropout of a protective func-tion). These indications are recorded.
In total 600 indications can be recorded. Oldest data are erased for newest data whenthe buffer is full.
2.20.1.3 Ground Fault Messages
For devices with sensitive ground fault detection, special ground fault records areavailable. Messages are provided if the protection is set for “Alarm Only” in Address3101, and the ground fault remains long enough for the time delay T-DELAY Pickupto expire.
Up to 15 messages can be recorded for the last 3 faults.
2.20.1.4 General Interrogation
The general interrogation which can be retrieved via DIGSI® 4 enables the current sta-tus of the SIPROTEC® device to be read out. All messages requiring general interro-gation are displayed with their present value.
2.20.1.5 Spontaneous Messages
The spontaneous annunciations that can be displayed via DIGSI® 4 are refreshed im-mediately, an event or status change occur.

2.20.1.6 Statistics
The messages in statistics are counters for the accumulation of interrupted current byeach of the breaker poles, the number of trips issued by the device to the breaker, andthe operating hours of the breaker and protected equipment. The interrupted currentsare in primary terms.
Statistics can be viewed on the LCD of the device, or on a PC running DIGSI® 4 andconnected to the operating or service interface.
A password is not required to read statistics; however, a password is required tochange or delete the statistics.
TransmittingInformation to aControl Center
If the device features a serial system port, stored information can be transmitted to acentral control and storage unit. Transmission is possible via different transmissionprotocols.

2.20.3 Commissioning Aids
2.20.3.1 Test Messages to the SCADA Interface during Test Operation
If the SIPROTEC®4 device is connected to a central or main computer system via theSCADA interface, then the information that is transmitted can be influenced. This isonly possible with some of the protocols available (see Table “Protocol-dependentfunctions” in the Appendix).
Depending on the type of protocol, all messages and measured values transferred tothe central control system can be identified with an added message “test operation”-bit while the device is being tested onsite (test mode). This identification prevents themessages from being incorrectly interpreted as resulting from an actual power systemdisturbance or event. As another option, all messages and measured values normallytransferred via the SCADA interface can be blocked during the testing (block datatransmission).
Data transmission block can be accomplished by controlling binary inputs, by usingthe operating panel on the device, or with a PC and DIGSI® 4 via the operator inter-face.
The activation and deactivation of the test mode and transmission block is describedin detail in the SIPROTEC® 4 System Manual.

Functions
2.20.3.2 Testing System Ports
If the device features a system port and uses it to communicate with the control center,the DIGSI® 4 device operation can be used to test if messages are transmitted cor-rectly.
A dialog box shows the display texts of all messages which were allocated to the sys-tem interface in the configuration matrix. In another column of the dialog box you canspecify a value for the messages you intend to test (e.g. ON/OFF). Having enteredpassword no. 6 (for hardware test menus) a message can then be generated. The as-sociated message will be issued and can then be retrieved in the operational annun-ciations of the SIPROTEC® device and also in the control center of the station.
A detailed description of the procedure is given in Subsection 3.3.2.
2.20.3.3 Checking the Binary Inputs and Outputs
The binary inputs, outputs, and LEDs of a SIPROTEC®4 device can be individuallyand precisely controlled in DIGSI® 4. This feature can be used, for example, to verifycontrol wiring from the device to substation equipment (operational checks), duringstart-up.
A dialog box shows all binary inputs and outputs and LEDs of the device with theirpresent status. The operating equipment, commands, or messages that are config-ured (masked) to the hardware components are displayed also. After entering pass-word no. 6 (for hardware test menus), you can switch to the opposite status in anothercolumn of the dialog box. You can energize every single output relay to check the wir-ing between 7SJ62/63/64 and the system without having to create the alarm allocatedto it.
Subsection 3.3.3 gives a detailed description of the procedure.
2.20.3.4 Triggering Oscillographic Recordings
At the end of commissioning, an investigation of the stability of the protection duringclosing operations. For this, closing test should be carried out. Oscillographic eventrecordings obtain the maximum information about the behavior of the 7SJ62/63/64.
Along with the capability of storing waveform data and SER information for faults, the7SJ62/63/64 also has the capability of capturing the same data when commands aregiven to the device via the service program DIGSI® 4, the serial interface, or a binaryinput. For the latter, the binary input must be masked with event 4,“>Trig.Wave.Cap.”. Triggering for the oscillographic recording then occurs whenthe input is energized. An auxiliary contact of the circuit breaker or primary switch maybe used to control the binary input for triggering.
An oscillographic recording that is externally triggered (that is, without a protective el-ement pickup or device trip) is processed by the device as a normal oscillographic re-cording with the exception that data are not given in the Trip Log for the event. Theexternally triggered record has a number for establishing a sequence.
Subsection 3.3.15 gives a detailed description of the procedure.

Average Calcula-tion
The selection of the time period for measured value averaging is set at address 8301DMD Interval. The first number specifies the averaging time window in minuteswhile the second number gives the frequency of updates within the time window. A set-ting of 15 Min., 3 Subs, for example, means that time average generation occursfor all measured values that arrive within 15 minutes, and that output is updated threetimes during the 15 minute window, or every 15/3 = 5 minutes.
The point in time where averaging begins (On The Hour, 15 After Hour, 30 After Hour or 45 After Hour) is set at address 8302 DMD Sync.Time. If thesettings for averaging are changed, then the measured values stored in the buffer aredeleted, and new results for the average calculation are only available after the settime period has passed.
Minimum andMaximum Values
The tracking of minimum and maximum values can be reset automatically at a pro-grammable point in time. To select this feature, address 8311 MinMax cycRESETshould be set to YES. The point in time when reset is to take place (the minute of theday in which reset will take place) is set at address 8312 MiMa RESET TIME. Thereset cycle in days is entered at address 8313 MiMa RESETCYCLE, and the beginningdate of the cyclical process, from the time of the setting procedure (in days), is enteredat address 8314 MinMaxRES.START.
Limit Values Phase currents and the averages of the currents and powers can be monitored. Theseare stationary monitors that cannot be used as pre-warning levels by time-overcurrentprotection, for example. The percentages are relative to the nominal device quantities.
Furthermore, it is possible to monitor the power factor, and connected 20 mA values(if any).
The settings are entered under MEASUREMENT in the sub-menu SET POINTS(MV) byoverwriting the existing values.

2.21 Breaker Control
General In addition to the protective functions described thus far, a Control command processis integrated in the SIPROTEC® 7SJ62/63/64 to coordinate the operation of circuitbreakers and other equipment in the power system. Control commands can originatefrom four command sources:
− Local operation using the keypad on the local user interface of the device
− Local or remote operation using DIGSI® 4
− Remote operation using the SCADA Interface (via IEC, Profibus)
− Automatic functions (e.g., using a binary input)
The device supports the operation of circuit breakers/switchgear. The number ofswitchgear devices to be controlled is, basically, limited by the number of binary inputsand outputs present. High security against inadvertent device operations can be en-sured if interlocking checks are enabled. A standard set of optional interlocking checksis provided for each command issued to circuit breakers/switchgear.
Devices with integrated or detached operator panel can control switchgear via the op-erator panel of the device. Depending on the type of operator panel (text display orgraphic display) the procedure is slightly different:
Operating Usingthe Keypad withText Display
Control commands can be initiated using the keypad on the local user interface of therelay. Using the navigation keys , , , , the CONTROLmenu can be accessedand the circuit breaker/switchgear to be operated can be selected. After entering apassword, a new window is displayed in which multiple control actions (close, open,cancel) are available and can be selected using the and keys. Next a securitycheck takes place. After the security check is completed, the key must bepressed again to carry out the command. If the key is not pressed within oneminute, the selection is cancelled. Cancellation via the key is possible at any timebefore the control command is issued.
Operation Usingthe Keypad withGraphic Display
Commands can be initiated using the keypad on the local user interface of the relay.For this purpose, there are three independent keys located below the graphic display.Pressing the key causes the Control Display to appear in the LCD. The other twocontrol keys and then become active, and control of switching devices be-comes possible. The LCD must be changed back to the default display for other, non-control, operational modes.
The navigation keys , , , are used to select the desired device in the Con-trol Display. The key or the key is then pressed to convey the intended con-trol command. After pressing the appropriate key, the selected device in the ControlDisplay begins to blink in the targeted-position, and a message to confirm the controlcommand is given. The key is pressed to confirm. Next a security check takesplace. After the security check is complete, the key must be pressed again to car-ry out the control command. If the key is not pressed within one minute, the se-lection is cancelled. Cancellation via the key is possible at any time before the con-trol command is issued.
After a successful switching operation, the Control Display shows the new position ofthe device, and the message “Control Executed” is given at the bottom of the dis-

play. For control commands with feedback, the message “Swgr. Feedback OK” isbriefly displayed.
If the selected control command is not accepted, because an interlocking condition isnot met, then an error message appears in the display. The message indicates whythe command was not accepted (see also SIPROTEC® 4–System Manual). This mes-sage must be acknowledged with before any further control commands can beissued.
Operation usingDIGSI® 4
The procedure for issuing control commands using the DIGSI® 4 program is describedin the SIPROTEC® 4–System Manual (Control of Switchgear).
Operation using theSCADA Interface
Commands can be issued remotely via the SCADA interface as well. Please checkMLFB order number to ensure that your individual relay has a SCADA interface mod-ule that supports this. Please refer to specific protocol documents for a complete listof supported commands (see SIPROTEC® 4–System Manual).
2.21.1 Types of Commands
Two (2) types of commands can be processed within the device:
− Control commands
− Internal / pseudo commands
Control Commands Control commands operate (OPEN/CLOSE) binary outputs. Examples are:
− Commands (e.g. operation of circuit breakers, etc.)
− Step Commands (e.g. raising and lowering transformer LTCs)
− Set-point Commands with configurable time settings (Petersen coils)
Internal / pseudoCommands
These commands do not directly operate binary outputs. They serve to initiate internalfunctions, simulate changes of state, or to acknowledge changes of state.
− Marking/Tagging commands are used to manually overwrite or set status functionsnormally controlled by binary inputs.
− Additionally, Tagging commands are issued to establish internal settings, such asswitching authority (remote vs. local), parameter set changeover, data transmissionblock to the SCADA interface, and measured value set-points.
− Acknowledgment and resetting commands for setting and resetting internal buffers.
− Status Information commands:
• Controlling activation of binary input status
• Binary Output Blocking

2.21.2 Steps in the Command Sequence
Safety mechanisms in the command sequence ensure that a command can only bereleased after a thorough check of preset criteria has been successfully concluded.Standard Interlocking checks are provided for each individual control command. Ad-ditionally, user-defined interlocking conditions can be programmed separately foreach command. The actual execution of the command is also monitored afterwards.The entire sequence of a command is described briefly in the following:
Check Sequence • Command Entry (e.g. using the keypad on the local user interface of the device)
− Check Password → Access Rights
− Check Switching Mode (interlocking activated/deactivated) → Selection of Deac-tivated Interlocking Recognition
• User configurable Interlocking checks that can be selected for each command
− Switching Authority (local, remote)
− Device Position (scheduled vs. actual comparison)
− Zone Controlled/Field Interlocking/ (logic using CFC)
− System Interlocking (centrally, using SCADA system or substation controller)
− Double Operation (interlocking against parallel switching operation)
− Protection Blocking (blocking of switching operations by protective functions)
• Fixed Command Checks
− Internal process time (software watch dog which checks the time for processingthe control action between initiation of the control and final close of the relay con-tact. After 1 second the control action will be aborted).
− Setting Modification in Process (if setting modification is in process, commandsare denied or delayed)
− Equipment not Present at Output (If a circuit breaker or other operable equipmentis not configured to a binary output, then the command is denied)
− Output Block (if an output block has been programmed for the circuit breaker,and is active at the moment the command is processed, then the command isdenied)
− Component Hardware Malfunction
− Command in Progress (only one command can be processed at a time for onecircuit breaker or switch)
− 1-of-n-check (for schemes with multiple assignments, such as common ground,whether a command has already been initiated for the affected output relay ischecked).
Monitoring theCommandExecution
− Interruption of a Command because of a Cancel Command
− Running Time Monitor (feedback message monitoring time)

2.21.3 Interlocking
The interlocking checks are divided into:
• System Interlocking: checked by a central control system such as SCADA or sub-station controller
• Zone Controlled/Bay Interlocking: checked in the device
System interlocking relies on the system data base in the substation or central controlsystem. Circuit breakers (or other equipment) that require system interlocking in acentral control system (Substation Controller) must be configured in their specific com-mands object properties box for the specific control device. Interlocking conditions canbe selected.
Zone Controlled/Bay Interlocking relies on the status of the circuit breaker and otherswitches that are connected to the relay. The extent of the interlocking checks is de-termined by the configuration of the relay.
For all commands, operation with interlocking (normal mode) or without interlocking(test mode) can be selected:
− for Local commands, by activation of “Normal/Test“-key switch ,
− for automatic commands, via command processing by CFC,
− for local / remote commands, using an additional interlocking disable command, viaProfibus.
2.21.3.1 Interlocked/Non-Interlocked Switching
The command checks that can be selected for the 7SJ62/63/64 relay are also referredto as “standard interlocking”. These checks can be activated (interlocked) or deacti-vated (non interlocked).
Deactivated interlock switching means the configured interlocking conditions are notchecked in the relay.
Interlocked switching means that all configured interlocking conditions are checkedwithin the command processing. If a condition could not be fulfilled, the command willbe rejected by a message with a minus added to it (e.g. “CO-”), immediately followedby an operation response information. Table 2-21 shows some types of commandsand messages. For the device the messages designated with *) are displayed in theevent logs, for DIGSI® 4 they appear in spontaneous messages.

Control abortion CA CA+/–
2557SJ62/63/64 ManualC53000-G1140-C147-1
Functions
The “plus” appearing in the message is a confirmation of the command execution: thecommand execution was as expected, in other words positive. The “minus” is a neg-ative confirmation, the command was rejected. Figure 2-87 shows the messages re-lating to command execution and operation response information for a successful op-eration of the circuit breaker.
The check of interlocking can be programmed separately for all switching devices andtags that were set with a tagging command. Other internal commands such as manualentry or abort are not checked, i.e. carried out independent of the interlocking.

Standard Interlock-ing Defaults(fixed programming)
The following is a list of Standard Interlocking Conditions that can be selected for eachcontrollable device. All of these are enabled as a default.
• Device Status Check (scheduled = actual): the switching command is rejected, andan error message is displayed, if the circuit breaker is already in the scheduled (de-sired) position. (If this check is enabled, then it works whether interlocking, e.g.zone controlled, is activated or deactivated.) This condition is checked in both inter-locked and non-interlocked status modes.
• System Interlocking/Substation Controlled: To check the system interlocking, a lo-cal command is transmitted to the central unit with Switch Authority = LOCAL. Aswitching device that is subject to system interlocking cannot be switched byDIGSI® 4.
• Zone Controlled/Bay Interlocking: All devices controlled by this relay can be inter-locked by the CFC logic.
• Blocked by protection: A CLOSE-command is rejected as soon as one of the pro-tective elements in the relay picks up. The OPEN-command, in contrast, can alwaysbe executed. Please be aware, activation of thermal overload protection elementsor sensitive ground fault detection can create and maintain a fault condition status,and can therefore block CLOSE commands. If the interlocking “Blocking by protection” is removed, consider that the restart blocking for motors will also bedisabled, and a CLOSE command to the motor would be possible. Restarting wouldthen have to be interlocked some other way. One method would be to use a specificinterlocking in the CFC logic.
• Double Operation Block: parallel switching operations are interlocked against oneanother; while one command is processed, a second cannot be carried out.
• Switch Authority LOCAL: When this interlocking check is enabled in the ObjectProperties dialog box, the status of Switching authority is checked prior to issuing acontrol command. If this particular setting is selected, a control command from theuser interface of the device is only allowed if the Key Switch (for devices without keyswitch via configuration) is set to LOCAL .

Breaker Control
• Switch Authority DIGSI: Switching commands can be issued locally or remotely viaDIGSI. As part of the safety features, the device will check the DIGSI configurationfile in regard to the virtual device number to ensure that the correct configuration fileis used. DIGSI must have the same virtual device number. It is important that onefile can not be reused with multiple relays. But it is possible to copy the file and usethe new file with another relay.
• Switch Authority REMOTE: When this interlocking check is enabled in the ObjectProperties dialog box, the status of Switching authority is checked prior to issuing acontrol command. If this particular setting is selected a control command from a re-mote DIGSI connection or via the SCADA interface is only allowed if the Key Switch(for devices without key switch via configuration) is set to REMOTE.
An overview for processing the interlocking conditions in the relay is shown by Figure2-88.

Control Logic usingCFC
For Zone Controlled (field interlocking), control logic can be developed, using theCFC. Via specific release conditions the information “released” or “bay interlocked”are available.
SwitchingAuthority (fordevices withoperator panel)
Switching authority configures the relay to perform Local/Remote Supervisory func-tions. Note, that only one source can have authority at a time. The following switchingauthority ranges are defined in the following priority sequence:
− LOCAL (commands are issued from the relay keyboard)
− DIGSI® 4
− REMOTE (commands are issued from SCADA)
The devices in housing of size 1/2 or 1/1 are equipped with key switches on the frontpanel. The top switch is reserved for switching authority between “Local” and “Re-mote” mode. The switching authority condition LOCAL allows commands from the userinterface of the relay, but not remote or DIGSI commands. The position “Remote“ en-ables remote control.
For devices in housing of size 1/3 the switching authority can be changed between“Remote” and “Local” in the operator panel after having entered the password or bymeans of CFC also via binary input and function key.
The switching authority condition DIGSI allows commands to be initiated usingDIGSI® 4. Commands are allowed for both a remote and a local DIGSI® 4 connection.
Configuration Programming:
1. Specific Device (e.g., switching device): Switching authority LOCAL (check forcommands initiated Locally via keypad):y/n
2. Specific Device (e.g., switching device): Switching authority REMOTE (check forSAS, REMOTE, or DIGSI commands:y/n

SC = source of command
SC = AUTO SICAM: Commands that are initiated internally (command processing inthe CFC) are not subject to switching authority and are therefore always allowed.
SwitchingAuthority (fordevices withoutoperator panel)
The dongle cable sets the switching authority of the device to “Remote”. The specifi-cations of the previous section apply.
Switching Mode(for devices withoperator panel)
There are three modes:
− Local
− Remote
− Auto
The switching mode determines whether selected interlocking conditions will be acti-vated or deactivated at the time of the switching operation.
The following switching modes are defined:
− Local commands (SC = LOCAL)
− interlocked, or
− non-interlocked switching.
The devices in housings of size 1/2 or 1/1 are equipped with key switches on the frontpanel. The bottom switch is reserved for switching mode. The “Normal” position allowsinterlocked switching while the “Interlocking OFF” position allows non-interlockedswitching. For devices in housings of size1/3 the switching authority can be changedbetween “Interlocked” and “Non-interlocked” in the operator panel after having enteredthe password or by means of CFC also via binary input and function key.

− Remote or DIGSI® 4 commands (SC = SAS, REMOTE, or DIGSI)
− interlocked, or
− non-interlocked switching. Here, deactivation of interlocking is accomplished viaa separate command. The position of the key-switch is irrelevant.
− Auto: For commands from CFC (SC = AUTO SICAM), the notes in the CFC hand-book should be referred to (e.g. component: BOOL to command)
Switching Mode(for devices withoutoperator panel)
The dongle cable sets the switching authority of the device to “Interlocked”. The spec-ifications of the previous section apply.
Zone Controlled/Field Interlocking
Zone Controlled (field interlocking) includes the verification that predetermined switch-gear position conditions are satisfied to prevent switching errors as well as verificationof the state of other mechanical interlocking such as High Voltage compartment doorsetc.
Interlocking conditions can be programmed separately, for each switching device, fordevice control CLOSE and/or OPEN. Processing of the status of the release conditionfor an operation switching device can be based on information acquired:
− directly, using a single point or double point indication (binary inputs), key-switch,or internal indication (marking), or
− with logic using CFC.
When a switching command is initiated, the actual status of all relevant switching de-vices is scanned cyclically.
Substation Control-ler (System Inter-locking)
Substation Controller (System interlocking) involves switchgear conditions of otherbays evaluated by a central control system.
Double Operation Parallel switching operations are interlocked. When this function is enabled only onecontrol can be issued at a time. All control objects are checked prior to issuing a com-mand.
Blocked by Protec-tion
When configured, the pickup of Protective elements blocks switching operations, con-figurable separately for both closing and tripping commands. Operations in progresswill also be aborted by the pickup of a protective element.
Device Position(Scheduled = Actu-al)
For switching commands, a check takes place whether the selected switching deviceis already in the scheduled/desired position (Open/Closed; scheduled/actual compar-ison). This means, if a circuit breaker is already in the CLOSED position and an at-tempt is made to issue a closing command, the command will be refused, with the op-erating message “scheduled condition equals actual condition”. If the circuit breaker/switchgear device is in the intermediate position, then this check is not performed.
BypassingInterlocks
Bypassing configured interlocks at the time of the switching action happens device-internal via interlocking recognition in the command job or globally via so-calledswitching modes.

− The switching modes “interlocked“ or “non-interlocked“ can be set via the keyswitch. The position “Test“ corresponds to non-interlocked switching and serves thespecial purpose of unlocking the standard interlocks.
REMOTE and DIGSI® 4
− Commands issued by SICAM® or DIGSI® 4 are unlocked via global switching modeREMOTE. A separate job order must be sent for the unlocking. The unlocking ap-plies only for one switching operation and for command caused by the samesource.
− Job order: command to object “switching mode REMOTE”, ON
− Job order: switching command to “switching device”

− Behavior is determined in the CFC block (“Bool to command“) via configuration
2.21.4 Recording and acknowledgement of commands
During the processing of the commands, independent of the further message routingand processing, command and process feedback information are sent to the messageprocessing centre. These messages contain message cause indication. The messag-es are entered in the event list.
Acknowledgementof commands to thedevice front
All messages which relate to commands that were issued from the device front “Com-mand Issued = Local” are transformed into a corresponding response and shown inthe display of the device. A listing of possible operating messages and their meaningis given in the SIPROTEC®4 System Manual.
Acknowledgementof commands to- Local- Remote- Digsi
The messages which relate to commands with the origin “Command Issued = Local/Remote/DIGSI” must be send independent of the routing (configuration on the serialdigital interface) to the initiating point.
The acknowledgement of commands is therefore not executed by a response indica-tion as it is done with the local command but by ordinary command and feedback in-formation recording.
Monitoring offeedbackinformation
The processing of commands monitors the command execution and timing of feed-back information for all commands. At the same time the command is sent, the moni-toring time is started (monitoring of the command execution). This time controlswhether the device achieves the required final result within the monitoring time. Themonitoring time is stopped as soon as the feedback information arrives. If no feedbackinformation arrives, a response “Timeout command monitoring time” appearsand the process is terminated.
Commands and information feedback are also recorded in the event list. Normally theexecution of a command is terminated as soon as the feedback information (FB+) ofthe relevant switchgear arrives or, in case of commands without process feedback in-formation, the command output resets.

Changing SettingGroups with BinaryInputs
If binary inputs are used to switch setting groups, note:
• Two binary inputs must be dedicated to the purpose of changing setting groupswhen four groups are to be switched. One binary input must be set for “>Set Group Bit 0”, the other input for “>Set Group Bit 1”. If either of these inputfunctions is not assigned, then it is considered as not controlled.
• To control two setting groups, one binary input set for “>Set Group Bit 0” issufficient since the binary input “>Set Group Bit 1”, which is not assigned, isconsidered to be not controlled.
• The status of the signals controlling the binary inputs to activate a particular settinggroup must remain constant as long as that particular group is to remain active.
Table 3-1 shows the relationship between “>Set Group Bit 0”, “>Set Group Bit 1”, and the setting groups A to D. Principal connection diagrams for the two binary in-puts are illustrated in Figure 3-8. The figure illustrates an example in which both SetGroup Bits 0 and 1 are configured to be controlled (actuated) when the associated bi-nary input is energized (high).

Trip CircuitSupervision
It must be noted that two binary inputs or one binary input and one bypass resistor Rmust be connected in series. The pick-up threshold of the binary inputs must thereforebe substantially below half the rated control DC voltage.
If two binary inputs are used for the trip circuit supervision, these binary inputs mustbe potential free i.o.w. not be commoned with each other or with another binary input.
If one binary input is used, a bypass resistor R must be employed (refer to Figure3-9). This resistor R is connected in series with the second circuit breaker auxiliarycontact (Aux2), to also allow the detection of a trip circuit failure when the circuit break-er auxiliary contact 1 (Aux1) is open, and the command relay contact has reset. Thevalue of this resistor must be such that in the circuit breaker open condition (thereforeAux1 is open and Aux2 is closed) the circuit breaker trip coil (TC) is no longer pickedup and binary input (BI1) is still picked up if the command relay contact is open.
Figure 3-9 Trip circuit supervision with one binary input
This results in an upper limit for the resistance dimension, Rmax, and a lower limit Rmin,from which the optimal value of the arithmetic mean should be selected.
To ensure the minimum voltage for the control of the binary input, Rmax is derived as:
So the circuit breaker trip coil does not remain energized in the above case, Rmin isderived as:

ers on the printed circuit boards inside the device. Follow the procedure described inSubsection 3.1.3, whenever hardware modifications are done.
Since the design of the modules differs, detailed information on hardware adaption islisted separately for each of the three device types 7SJ62, 7SJ63 and 7SJ64.
Power SupplyVoltage
There are different ranges for the power supply voltage of the various power supplies.Refer to the data for the 7SJ62/63/64 ordering numbers in Section A.1 of the Appen-dix. The power supplies of the different variants are largely interchangeable by modi-fying the position of the jumpers. Jumper settings determine the rating. The assign-ment of these jumpers to the supply voltages is described in Subsubsections 3.1.3.3to 3.1.3.5, separately for 7SJ62, 7SJ63 and 7SJ64. When the relays are delivered,these jumpers are set according to the name-plate sticker. Generally, they need notbe altered.
Life Contact The life contacts of the devices are changeover contacts. In 7SJ62 all three connec-tions are conducted to device terminals. In case of 7SJ63 and 7SJ64 the NC contactor the NO contact can be connected to the device connections via a plug-in jumper(X40). The assignment of the plug-in jumper to the type of contact and the location ofthe jumper is described in Subsubsections 3.1.3.4 and 3.1.3.5 for the models 7SJ63and 7SJ64.
Nominal Currents The input transformers of the devices are set to a nominal current of 1 A or 5 A withjumpers. The position of the jumpers are set according to the name-plate sticker. Theassignment of the jumpers to the nominal rate and the arrangement of the jumpers isdescribed in 3.1.3.3 to 3.1.3.5, separately for 7SJ62, 7SJ63 and 7SJ64.
All jumpers must be set for the same nominal current, i.e. a jumper (X61 to X63) onejumper for each input transformer and additionally one jumper X 60.
Jumper X64 for the ground path is set to 1 A or 5 A (depending on the ordered variant)for the models with normal 1/5-A transformer irrespective of the other jumper posi-tions.
Jumper X64 is omitted for models featuring a sensitive ground fault input for the settingrange from 0.001 to 1.500 A.
Control Voltagesfor Binary Inputs
When the device is delivered from the factory, the binary inputs are set to operate witha voltage that corresponds to the rated DC voltage of the power supply. In general, tooptimize the operation of the inputs, the pick-up voltage of the inputs should be set tomost closely match the actual control voltage being used. Each binary input has apick-up voltage that can be independently adjusted; therefore, each input can be setaccording to the function performed.
A jumper position is changed to adjust the pick-up voltage of a binary input. The phys-ical arrangement of the binary input jumpers in relation to the pick-up voltages is de-scribed in 3.1.3.3 to 3.1.3.5 separately for 7SJ62, 7SJ63 and 7SJ64.
Note:
If nominal current ratings are changed exceptionally, then the new ratings must beregistered in addresses 0205 CT SECONDARY/ 0218 Ignd-CT SEC in the Power System Data 1 (P.System Data 1) (see Subsection 2.1.3).

Installation and Connections
Type of Contact forBinary Outputs
Input and output boards can contain relays of which the contact can be set as normallyclosed or normally open contact. Therefore it is necessary to rearrange a jumper. Sub-sections 3.1.3.3 to 3.1.3.5 describe separately for 7SJ62, 7SJ63 and 7SJ64 to whichrelays on which modules this applies.
ReplacingInterfaces
Only serial interfaces of devices for panel and cubicle flush mounting as well as ofmounting devices with detached operator panel or without operator panel are replace-able. For more details on this matter refer to Subsubsection 3.1.3.6, “Replacing Inter-faces”.
ConfiguringRS232/RS485
When the device is delivered from the factory, the serial interfaces are matched to theordered version according to the 11th and 12th figure of the ordering code of the de-vice (or to the additional information of the ordering code). The configuration is deter-mined by jumpers on the interface modules (“RS232/RS485” in Subsection 3.1.3.6).
Termination ofSerial Interfaces
If the device is equipped with a serial RS485 port or Profibus, they must be terminatedwith resistors at the last device on the bus to ensure reliable data transmission. Forthis purpose, the printed circuit board of the central processor unit CPU and the RS485or Profibus interface module are provided with terminating resistors that can be con-nected to the system by means of jumpers. It is important to use only 1 of the options.The position of the jumpers on the printed circuit board of the corresponding centralprocessor unit CPU is described in Subsubsections 3.1.3.3 to 3.1.3.5, see “ProcessorBoard CPU” and the position of the jumpers on the interface modules in Subsubsec-tion 3.1.3.6, see „RS485/RS232“ und „Profibus (FMS/DP) DNP3.0/Modbus“. Bothjumpers must always be plugged in the same way.
As delivered from the factory, the resistors are switched out.
Spare Parts Spare parts can be the battery that provides for storage of the data in the battery-buff-ered RAM in case of a power failure, and the miniature fuse of the internal power sup-ply. Their physical location is shown in Figures 3-16, 3-17, 3-19, 3-20 and 3-23. Theratings of the fuse are printed on the board next the fuse itself. When exchanging thefuse, please observe the hints given in the SIPROTEC®4 System Manual in the chap-ter “Maintenance”.
3.1.3.2 Disassembly of the Device
Important!It is assumed for the following steps that the the device is not operative.
To perform work on the printed circuit boards, such as checking or moving switchingelements or exchanging modules, proceed as follows:
Note:
If the 7SJ62/63/64 performs trip circuit monitoring, two binary inputs, or one binary in-put and a resistor, are connected in series. The pick-up voltage of these inputs mustbe less than half of the nominal DC voltage of the trip circuit.

Installation and Commissioning
Prepare area of work. Provide a grounded mat for protecting components subject todamage from electrostatic discharges (ESD). The following equipment is needed:
− screwdriver with a 5 to 6 mm wide tip,
− 1 Philips screwdriver,
− 4.5 mm socket or nut driver.
Unfasten the screw-posts of the D-subminiature connector on the back panel at loca-tion “A” and “C” (7SJ64). This activity does not apply if the device is for surface mount-ing.
If there are additional interfaces on location “B” , “C” and “D” next to the interfaces atlocation “A” to “C” (7SJ64), remove the screws located diagonally to the interfaces.This activity is not necessary if the device is for surface mounting.
Remove the four or six caps on the front cover and loosen the screws that becomeaccessible.
Carefully take off the front cover. The front cover is connected to the CPU board witha short ribbon-cable. With device versions with a detached operator panel it is possibleto remove the front cover of the device right after having unscrewed all screws.
Disconnect the ribbon cable between the front cover and the CPU board () at thefront cover side. To disconnect the cable, push up the top latch of the plug connectorand push down the bottom latch of the plug connector. Carefully draw out the plug con-nector.This action does not apply to the device version with detached operator panel. How-ever, on the central processor unit CPU () the 7-pole plug connector X16 behind theD-subminiture connector and the plug connector of the ribbon cable (connected to the68pole plug connector on the rear side) must be removed.
Disconnect the ribbon cables between the CPU unit () and the input/output printedcircuit boards (depending on the version () to ()).
Remove the boards and set them on the grounded mat to protect them from ESD dam-age. A greater effort is required to withdraw the CPU board, especially in versions ofthe device for surface-mounting, because of the communication connectors.
Caution!
Jumper-setting changes that affect nominal values of the device render the orderingnumber and the corresponding nominal values on the nameplate sticker invalid. Ifsuch changes are necessary, the changes should be clearly and fully noted on the de-vice. Self adhesive stickers are available that can be used as replacement name-plates.
Caution!
Electrostatic discharges through the connections of the components, wiring, plugs,and jumpers must be avoided. Wearing a grounded wrist strap is preferred. Otherwise,first touch a grounded metal part.

CTS With jumper X111, CTS is activated which is necessary for the communication withthe modem.
*) Presetting
Jumper setting 2–3: the connection to the modem is usually done with star coupleror optical fibre converter. Therefore the modem control signal according to RS232standard DIN 66020 is not available. Modem signals are not required since communi-cation to SIPROTEC® devices is always carried out in the half duplex mode. Use con-netion cable with ordering number 7XV5100–4.
Jumper setting 1–2: this setting makes the modem signal available, i. e. for a directRS232-connection between the SIPROTEC® device and the modem this setting canbe selected optionally. We recommend to use a standard RS232 modem connectioncable (converter 9-pole on 25-pole).
Note: For a direct connection to DIGSI® 4 with interface RS232 jumper X111 must beplugged in position 2–3.
Terminating Resis-tors
If there are no external matching resistors in the system, the last devices on aRS485-bus must be configured via jumpers X103 and X104.
Note: Both jumpers must always be plugged in the same way!
Currently no function is assigned to the jumper X90. The presetting is 1-2.
The terminating resistors can also be connected externally (e.g. to the connectionmodule). In this case, the terminating resistors located on the RS485 interface moduleor the resistors located directly on the processor circuit board C–CPU–2 must be dis-connected.

Installation and Connections
Figure 3-29 Location of the jumpers for configuration of RS232
CTS With jumper X11, CTS is activated which is necessary for the communication with themodem.
*) Default Setting
Jumper setting 2–3: the connection to the modem is usually done with star coupleror optical fibre converter. Therefore the modem control signal according to RS232standard DIN 66020 is not available. Modem signals are not required since communi-cation to SIPROTEC® devices is always carried out in the half duplex mode. Use con-netion cable with ordering number 7XV5100–4.
Jumper setting 1–2: this setting makes the modem signal available, i. e. for a directRS232-connection between the SIPROTEC® device and the modem this setting canbe selected optionally. We recommend to use a standard RS232 modem connectioncable (converter 9-pole on 25-pole).
Note: For a direct connection to DIGSI® 4 with interface RS232 jumper X11 must beplugged in position 2–3.
RS485/RS232 Interface RS485 can be modified to interface RS232 and vice versa, according to Fig-ure 3-29.
Termination Busbar capable interfaces require a termination at the last device of the bus, i.e. ter-minating resistors must be connected. For 7SJ62/63/64 this applies to the variant withinterface RS485 or Profibus.
The terminating resistors are located on the corresponding interface module that ismounted to the processor input/output board CPU ( in Figure 3-10 to 3-15).

Installation and Connections
3.1.3.7 Reassembly of Device
To reassemble the device, proceed as follows:
Carefully insert the boards into the case. The installation locations of the boards areshown in Figure 3-10 to 3-15.For the model of the device designed for surface mounting, use the metal lever to in-sert the processor circuit board CPU board. The installation is easier with the lever.
First plug the plug connectors of the ribbon cable into the input/output boards I/O andthen onto the processor module CPU. Be careful to not bend any of the connectingpins! Do not use force!
Insert the plug connector of the ribbon cable between the processor moduleCPU and the front cover into the socket of the front cover.For the version with detached operator panel the latter is to be ignored. Instead theplug connector of the ribbon cable connected to a 68pole plug connector on the rearside of the device must be plugged into the plug connector of the processor circuitboard CPU. The 7-pole plug connector X16 connected to the ribbon cable must beplugged behind the D-subminiature female connector. Since the connection is protect-Press the latches of the plug connectors together.
Replace the front cover and secure to the housing with the screws.
Replace the covers.
Re-fasten the interfaces on the rear of the device housing.This activity is not necessary if the device is designed for surface mounting.

PC OperatingInterface at Front
When the recommended communication cable is used, correct connection betweenthe SIPROTEC® device and the PC is automatically ensured. See the Appendix, Sub-section A.1 for an ordering description of the cable.
ServicePort
Check the data connection if the service (port C) is used to communicate with the de-vice via fix wiring or a modem. If the service port is used as input for one or two ther-moboxes, verify the interconnection according to one of the connection examples giv-en in the Appendix A.3.4.
System (SCADA)Interface
When a serial interface of the device is connected to a central substation control sys-tem, the data connection must be checked. A visual check of the transmit channel andthe receive channel is important. Each connection is dedicated to one transmission di-rection. The data output of one device must be connected to the data input of the otherdevice, and vice versa.
The data cable connections are designated in sympathy with DIN 66020 and ISO2110 (see also Table 3-35):
− TxD data transmit
− RxD data receive
− RTS request to send
− CTS clear to send
− DGND signal/chassis ground

Checking Connections
The cable shield is to be grounded at both ends so that potential differences cannotcause circulating currents to flow along the shield. In areas of extremely strong EMCinterferences, the interference immunity factor can be improved by leading the groundwire in a separate shielded pair of strands.
Additional Interface(only7SJ64)
The additional interface available only for 7SJ64 (port D) serves for signal injection ofone or two thermoboxes. The interconnection according to one of the connection ex-amples in Appendix (A.3.4) must be checked.
.
*) Pin 7 also can carry the RS 232 RTS signal to an RS 485 interface. Pin 7 must thereforenot be connected!
Termination The RS485 interface is capable of half-duplex service with the signals A/A' and B/B'with a common relative potential C/C' (DGND). Verify that only the last device on thebus has the terminating resistors connected, and that the other devices on the bus donot. The jumpers for the terminating resistors are on the interface module RS485(Figure 3-30) or on the Profibus module RS485 (Figure 3-31) or for 7SJ64 also directlyon C–CPU–2 (see Figure 3-23 and Table 3-23). The terminating resistors can also beconnected externally (e.g. to the connection module) as illustrated in Figure 3-24. Inthis case, the terminating resistors located on the RS485 or the Profibus interfacemodule or directly on the printed circuit board of the C–CPU–2 board of 7SJ64 mustbe disconnected.
If the bus is extended, make sure again that only the last device on the bus has theterminating resistors switched-in, and that all other devices on the bus do not.

TimeSynchronizationInterface
Either 5-VDC-, 12-VDC- or 24-VDC- time synchronization signals can be processed ifthe connections are made as indicated in Table 3-36.
Optical Fibers Signals transmitted via optical fibers are unaffected by interference. The fibers guar-antee electrical isolation between the connections. Transmit and receive connectionsare shown with the symbols for transmit and for receive.
The normal setting for the optical fiber interface is”Light off.” If this setting is to bechanged, use the operating program DIGSI® 4, as described in the SIPROTEC® 4–System Manual.
TemperatureMeter (Thermobox)
If one or two 7XV566 temperature meters are connected, check their connections tothe ports (port C or D).
Verify also the termination: the terminating resistors must be connected to 7SJ62/63/64 (see Subsection 3.1.3.6 at “Termination“.
For further information refer to the operating manual of 7XV566. Check the transmis-sion settings at the temperature meter. Besides the baudrate and the parity observealso the bus number.
• For connection of one 7XV566 thermobox:Bus number = 0 (to be set at 7XV566)
• For connection of two 7XV566 thermoboxes:Bus number = 1 for the 1st thermobox (to be set at 7XV566 for RTD1 to 6),Bus number = 2 for the 2nd thermobox (to be set at 7XV566 for RTD7 to 12).
Please observe that the detector input 1 (RTD1) of the 1st thermobox is reserved forthe input of the ambient temperature/coolant temperature for the overload protection.

Checking Connections
3.2.2 Checking Power Plant Connections
If an undervoltage element (27) is enabled and ON and the current supervision of the27 element is OFF, then the 27 element will immediately trip when voltage is removedfrom the device. This will prevent the user from being able to set the device or performother actions. To avoid this possible problem, current supervision must be set ON orthe voltage protection must be blocked. This can be accomplished via the operation(see note in Subsection 2.5.2.2).
Before the device is energized for the first time, the device should be in the final oper-ating environment for at least 2 hours to equalize the temperature, to minimize humid-ity and avoid condensation. Connection are checked with the device at its final loca-tion. The plant must first be switched off and grounded.
Protective switches (e.g. test switches, fuses, or miniature circuit breakers) for thepower supply and the measured voltages must be opened.
Check the continuity of all current and voltage transformer connections against thesystem and connection diagrams:
Are the current transformers grounded properly?
Are the polarities of the current transformers the same?
Is the phase relationship of the current transformers correct?
Are the voltage transformers grounded properly?
Are the polarities of the voltage transformers correct?
Is the phase relationship of the voltage transformers correct?
Is the polarity for current input I4 correct (if used), also refer to Subsection 3.1.2,“Currents“?
Is the polarity for voltage input U4 correct (only 7SJ64 and if used, e.g. with brokendelta winding or busbar voltage), cf. also Subsection 3.1.2.3 “Connection Examplesfor 7SJ64“.
Check the functions of all test switches that may be installed for the purposes of sec-ondary testing and isolation of the device. Of particular importance are test switchesin current transformer circuits. Be sure these switches short-circuit the current trans-formers when they are in the test mode (open).
Warning!The following procedures are carried out with dangerous voltages present. Therefore,only qualified people who are familiar with and adhere to the safety procedures andprecautionary measures shall perform the procedures.
Caution!
Operating the device on a battery charger without a connected battery can lead to un-usually high voltages and consequently, the destruction of the device. For limit valuessee Sub-section 4.2.1 under Technical Data.

Attach the front panel and tighten the screws.
Connect an ammeter in the supply circuit of the power supply. A range of about 1 Afor the meter is appropriate.
Close the protective switches to apply voltage to the power supply. The measuredsteady state current should be insignificant. Transient movement of the ammetermerely indicates the charging current of capacitors.
Check the polarity and magnitude of the voltage at the device terminals.
Remove the voltage from the power supply by opening the protective switches.
Disconnect the measuring test equipment; restore the normal power supply connec-tions.
Apply voltage to the power supply.
Close the protective switches for the voltage transformers.
Verify that the voltage phase rotation at the device terminals is correct. Note that thedevice can be set for ABC rotation or ACB rotation under Address 0209 PHASE SEQ.in P.System Data1.

When testing the device with secondary test equipment, make sure that no other mea-surement quantities are connected and that the trip and close commands to the circuitbreakers and other primary switches are disconnected from the device unless ex-pressly stated.
For the commissioning switching operations have to be carried out. A prerequisite forthe prescribed tests is that these switching operations can be executed without dan-ger. They are accordingly not meant for operational checks.
Warning!When operating an electrical device, certain parts of the device inevitably have dan-gerous voltages. Severe personal injury or property damage can result if the device isnot handled properly.
Only qualified people shall work on and around this device after becoming thoroughlyfamiliar with all warnings and safety notices in this instruction manual as well as withthe applicable safety steps, safety regulations, and precautionary measures.
The main points to observe are:
• The device is to be grounded to the substation ground before any other connectionsare made.
• Hazardous voltages can exist in the power supply and at the connections to currenttransformers, voltage transformers, and test circuits.
• Hazardous voltages can be present in the device even after the power supply volt-age has been removed, i.e. capacitors can still be charged.
• After removing voltage from the power supply, wait a minimum of 10 seconds be-fore re-energizing the power supply. This wait allows the initial conditions to be firm-ly established before the device is re-energized.
• The limit values given in Technical Data (Chapter 10) must not be exceeded, neitherduring testing nor during commissioning.
DANGER!Current transformer secondary circuits must be short-circuited before the cur-rent leads to the device are disconnected!
If test switches are installed that automatically short-circuit the current transformer cir-cuits, opening these test switches (placing them in the "Test" position) is sufficient pro-vided the short-circuit function has been previously tested.

3.3.1 Testing mode and transmission blocking
If the SIPROTEC®4 device is connected to a central or main computer system via theSCADA interface, then the information that is transmitted can be influenced. This isonly possible with some of the protocols availabel (see Table “Protocol-dependentfunctions” in the Appendix).
If Test mode is set ON, then a message sent by the device to the main system hasan additional test bit. This bit allows the message to be recognized as resulting fromtesting and not an actual fault or power system event.
If DataStop is set ON, transmission to the SCADA is blocked.
Both of these features should be checked. The procedures for setting Test mode andDataStop are described in the SIPROTEC® 4 System Manual. Note that whenDIGSI® 4 is being used, the program must be in the Online operating mode for thetest features to be used.
3.3.2 Checking the System (SCADA) Interface
PreliminaryRemarks
Provided that the device is equipped with a system (SCADA) interface that is used forthe communication with a substation, it is possible to test via the DIGSI® 4 operationalfunction if messages are transmitted correctly. Do not apply this test function in thereal operating mode of the device.
Warning!Primary test may only be carried out by qualified personnel, who are familiar with thecommissioning of protection systems, the operation of the plant and the safety rulesand regulations (switching, earthing, etc.).
DANGER!The transmission and reception of messages via the system (SCADA) interfaceby means of the testing mode is the real exchange of information between theSIPROTEC®4 device and the substation. Connected equipment such as circuitbreakers or disconnectors can be operated as a result of these actions!
Note:
After termination of this test, the device will reboot. All annunciation buffers areerased. If required, these buffers should be extracted with DIGSI® 4 prior to the test.

Structure of theTest Dialogue Box
The dialogue box is divided into three groups: BI for binary inputs, REL for outputrelays, and LED for light-emitting diodes. Each of these groups is associated with anappropriately marked switching area. By double-clicking in an area, components with-in the associated group can be turned on or off.
In the Status column, the present (physical) state of the hardware component isdisplayed. The binary inputs and outputs are indicated by an open or closed switchsymbol, the LEDs by a dark or illuminated LED symbol.
The possible intended condition of a hardware component is indicated with clear textunder the Scheduled column, which is next to the Status column. The intendedcondition offered for a component is always the opposite of the present state.
The right-most column indicates the commands or messages that are configured(masked) to the hardware components.
Changing theHardwareConditions
To change the condition of a hardware component, click on the associated switchingfield in the Scheduled column.
Password No. 6 (if activated during configuration) will be requested before the firsthardware modification is allowed. After entry of the correct password a conditionchange will be executed.
Further condition changes remain possible while the dialog box is open.
Test of the BinaryOutputs
Each individual output relay can be energized allowing a check of the wiring betweenthe output relay of the 7SJ62/63/64 and the plant, without having to generate the mes-sage that is assigned to the relay. As soon as the first change of state for any one ofthe output relays is initiated, all output relays are separated from the internal devicefunctions, and can only be operated by the hardware test function. This implies that a

Installation and Commissioning
switching signal to an output relay from e.g. a protection function or control commandcannot be executed.
Ensured that the switching of the output relay can be executed without danger (seeabove under DANGER!).
Each output relay must be tested via the corresponding Scheduled–cell in the di-alog box.
The test sequence must be terminated (refer to margin heading “Exiting the Proce-dure”), to avoid the initiation of inadvertent switching operations by further tests.
Test of the BinaryInputs
To test the wiring between the plant and the binary inputs of the 7SJ62/63/64 the con-dition in the plant which initiates the binary input must be generated and the responseof the device checked.
To do this, the dialogue box Hardware Testmust again be opened to view the phys-ical state of the binary inputs. The password is not yet required.
Each state in the plant which causes a binary input to pick up must be generated.
The response of the device must be checked in the Status–column of the dialoguebox. To do this, the dialogue box must be updated. The options may be found belowunder the margin heading “Updating the Display”.
If however the effect of a binary input must be checked without carrying out any switch-ing in the plant, it is possible to trigger individual binary inputs with the hardware testfunction. As soon as the first state change of any binary input is triggered and thepassword nr. 6 has been entered, all binary inputs are separated from the plant andcan only be activated via the hardware test function.
Terminate the test sequence (see above under the margin heading „Exiting the Pro-cedure“).
Test of the LED’s The LED’s may be tested in a similar manner to the other input/output components.As soon as the first state change of any LED has been triggered, all LEDs are sepa-rated from the internal device functionality and can only be controlled via the hardwaretest frunction. This implies that no LED can be switched on anymore by e.g. a protec-tion function or operation of the LED reset key.
Updating theDisplay
When the dialog box Hardware Test is opened, the present conditions of the hard-ware components at that moment are read in and displayed. An update occurs:
− for each harware component, if a command to change the condition is successfullyperformed,
− for all hardware components if the Update button is clicked,
− for all hardware components with cyclical updating if the Automatic Update (20sec) field is marked.
Exiting theProcedure
To end the hardware test, click on Close. The dialog box closes. The device becomesunavailable for a brief start-up period immediately after this. Then all hardware com-ponents are returned to the operating conditions determined by the plant settings.

3.3.4 Tests for the Circuit Breaker Failure Protection
If the device provides a breaker failure protection and if this is used, the integration ofthis protection function in the system must be tested under practical conditions.
Due to the variety of application options and the available system configurations, it isnot possible to make a detailed description of the necessary tests. It is important toconsider the local conditions and the protection and plant drawings.
It is advised to isolate the circuit breaker of the tested feeder at both sides, i.e. to keepthe busbar isolator and the line isolator open, in order to ensure operation of the break-er without risk.
The trip command of the tested Multi-Functional Protective Relay is made ineffectiveso that the local breaker can be tripped only by the breaker failure protection functionof 7SJ62/63/64.
Although the following lists do not claim to be complete it may also contain pointswhich are to be ignored in the current application.
Circuit BreakerAuxiliary Contacts
If the circuit breaker auxiliary contacts are connected to the device, these provide anessential input to the functionality of the breaker failure protection. Make sure thecorrect assignment has been checked (Section 3.3.3).
External StartConditions
If the breaker failure protection can also be started by external protection devices, theexternal start conditions should be checked.
In order for the breaker failure protection to be started, a current must flow at least viathe monitored phase. This may be a secondary injected current.
Starting by trip command of the external protection:binary input functions “>50BF ext SRC“ (FNo 01431) (in spontaneous or faultmessages).
After every start, the message “50BF ext Pickup“ (FNo 01457) must appear inthe spontaneous or fault messages.
After time expiration TRIP-Timer (address 7005) tripping command of the circuitbreaker failure protection.
Switch off test current.
If BF start is possible without current flow:
To close the circuit breaker to be monitored to both sides with the disconnectorswitches open.
Caution!
Also for tests on the local circuit breaker of the feeder a trip command to the surround-ing circuit breakers can be issued for the busbar. Therefore the tripping of the sur-rounding circuit breakers (busbar) must be deactivated, e. g. by switching off the cor-responding control voltages.Nevertheless ensure that trip remains possible in case ofa real primary fault if parts of the power plant are in service.
3297SJ62/63/64 ManualC53000-G1140-C147–1
Installation and Commissioning
BF start by trip command of the external protection without current flow:binary input functions “>50BF ext SRC“ (FNo 01431) ((in spontaneous or faultmessages).
After every start, the message “50BF ext Pickup“ (FNo 01457) must appear inthe spontaneous or fault messages.
After time expiration TRIP-Timer (address 7005) tripping command of the circuitbreaker failure protection.
Opening the circuit breaker again.
Busbar tripping For testing the distribution of the trip commands in the substation in the case of break-er failures it is important to check that the trip commands to the surrounding circuitbreakers is correct.
The surrounding circuit breakers are all those which need to trip when the feeder cir-cuit breaker fails. These are therefore the circuit breakers of all feeders which feed thebusbar or busbar section to which the feeder with the fault is connected.
A general detailed test guide cannot be specified because the layout of the surround-ing circuit breakers largely depends on the switchgear topology.
In particular with multiple busbars the trip distribution logic for the surrounding circuitbreakers must be checked. Here it should be checked for every busbar section that allcircuit breakers which are connected to the same busbar section as the feeder circuitbreaker under observation are tripped, and no other breakers.
Tripping of theRemote End
If the trip command of the circuit breaker failure protection must also trip the circuitbreaker at the remote end of the feeder under observation, the transmission channelfor this remote trip must also be checked.
Termination All temporary measures taken for testing must be undone, e.g. especially switchingstates, interrupted trip commands, changes to setting values or individually switchedoff protection functions.
3.3.5 Testing User-Defined Functions
A 7SJ62/63/64 has a vast capability for allowing functions to be defined by the user,especially with the CFC logic. Any special function or logic added to the device mustbe checked.
Naturally, general test procedures cannot be given. Rather, the configuration of theseuser-defined functions and the necessary associated conditions must be known andverified. Of particular importance are the possible interlocking conditions of the circuitbreakers and other primary switching devices. They must be considered and tested.

3.3.6 Current, Voltage, and Phase Rotation Testing
Load Current≥ [10% IN]
The connections of the current and voltage transformers are tested using primaryquantities. Secondary load current of at least 10 % of the nominal current of the deviceis necessary. With proper connections of the measuring circuits, none of the mea-sured-values supervision elements in the device should pick up. If an element detectsa problem, the relevant condition can be viewed in the Event Log. If current summationerrors occur, then check the matching factors. See Subsection ).
Messages from the symmetry monitoring could occur because there actually areasymmetrical conditions in the network. If these asymmetrical conditions are normalservice conditions, the corresponding monitoring functions should be made less sen-sitive. See Subsection 2.10.2).
Current andVoltage Values
Currents and voltages can be seen in the display field on the front of the device underMeasurement. The quantities can also be viewed under Measurement in theDIGSI® 4 window. The currents and voltages displayed by the device can be com-pared to the quantities measured by an independent source.
If the measured values are not plausible, the connection must be checked and correct-ed after the line has been isolated and the current transformer circuits have beenshort-circuited. The measurements must then be repeated.
Phase Rotation The phase rotation must correspond to the configured phase rotation, in general aclockwise phase rotation. If the system has an anti-clockwise phase rotation, this musthave been considered when the power system data was set (address 0209 PHASE SEQ., refer to Subsection ). If the phase rotation is incorrect, the alarm “Fail Ph. Seq.“ (FNo 00171) is generated. The measured value phase allocation must bechecked and corrected, if required, after the line has been isolated and current trans-formers have been short-circuited. The phase rotation check must then be repeated.
VoltageTransformerMiniature CircuitBreaker (VT mcb)
The VT mcb of the feeder must be opened. The measured voltages in the operationalmeasured values appear with a value close to zero (small measured voltages are ofno consequence).
Check in the spontaneous messages that the VT mcb trip was entered (message“>FAIL:FEEDER VT ON“ in the spontaneous messages). Beforehand it has to be as-sured that the position of the VT mcb is connected to the device via a binary input.
Close the VT mcb: The above messages appear under the spontaneous messagesas “OFF”, i.e. “>FAIL:FEEDER VT OFF“.
If one of the events does not appear, the connection and routing of these signalsmust be checked.
If the “ON“–state and “OFF“–state are swapped, the contact type (H–active or L–active)must be checked and remedied.
7SJ64 only If a busbar voltage is used (for synchronism check) and the assigned VT mcb is con-nected to the device, the following function must also be checked:
If the VT mcb is open the message “>FAIL: BUS VT ON“ appears, if it is closed themessage “>FAIL: BUS VT OFF“ is displayed.
Switch off the protected power line.

3.3.7 Testing the Reverse Interlocking Scheme (if applicable)
This testing causes trip contacts of the 7SJ62/63/64 to close. If tripping of the relevantcircuit breakers and primary interrupting devices is to be avoided, the 7SJ62/63/64 tripcontacts must be isolated. Proper backup relaying should exist.
An operational check of the reverse interlocking scheme might cause tripping by theprotective relays that block the 7SJ62/63/64 (depending on the procedure used). If theblocking relays will trip, the trip contacts that control primary interrupting devices mustbe isolated if the devices are not to be operated. Again, proper backup relaying shouldexist.
Simple methods of testing and operational checking a reverse interlocking scheme areillustrated with an example. In this example, the 50-2 element and the 50N-2 elementof the 7SJ62/63/64 are employed in a reverse interlocking scheme that provides busprotection in a radial distribution system with three feeders. The tripping of both ele-ments is blocked when Binary Input 1 is energized. The input mask is [>BLOCK 50-2 (H) or >BLOCK 50N-2 (H)]. The elements have slight time delays to provide co-ordination with the blocking protective relays. The blocking relays are the three feederrelays. Each feeder relay has a blocking contact programmed to close when the 51element or 51N element picks up. The three contacts are connected in parallel to applycontrol voltage to Binary Input 1 when any one of them closes.
An actual scheme might employ elements and binary inputs other than those given inthe example. The binary inputs could also be set to block tripping when the inputs arede-energized. The blocking devices might be configured differently as well. In anycase, testing and operationally checking a reverse interlocking scheme are typicallysimple. The procedures below can be adapted as needed.
With the 7SJ62/63/64 isolated from the current transformers and tripping circuits, in-ject test current into any one phase current input and the ground current input. Slowlyramp-up the current until the pickup values of 50-2 and 50N-2 are found (monitor con-tacts or LEDs). Slowly decrease the current until the dropout values are found. Verifythat the pickup and dropout values are as expected.
The time delays of the elements can be measured with a timer set to start on the ap-plication of current and stop on the closure of the trip contact masked to close wheneither 50-2 or 50N-2 trips. Test one element at a time. For either element, first set thetime delay for 0.00 second. Suddenly apply current greater than the pickup value.Record the time. Repeat the test with the time delay included. The difference betweenthe results provides an estimate of the time delay. Be sure the time delays are as ex-pected.
The tripping block can be verified by manually applying voltage to Binary Input 1, andinjecting a test current above the pickup of the element under consideration, for a timeperiod much longer than the time delay setting.
To operationally check the scheme, current can be simultaneously injected into the7SJ62/63/64 and one of the feeder relays. The feeder relay must be isolated from cur-rent transformers and trip circuits of primary equipment. Proper backup relaying
Caution!
During testing, observe the current ratings of the inputs given in Technical Data, Sub-section 4.1.1. Allow a cool-down period if the continuous ratings are exceeded.

Commissioning
should be available. The magnitude of the test current must be high enough to pickupboth the feeder blocking element and the 7SJ62/63/64 tripping element. (The blockingelement could be less sensitive in secondary terms.) Suddenly apply the current andverify that 50-2 and 50N-2 are blocked. Suddenly remove the current and verify that50-2 and 50N-2 do not trip. If the blocking element has an equal or higher sensitivitythan the tripping element, then tests in which the current is slowly decreased can bedone to verify that there are no element dropout-miscoordinations.
Repeat the testing for each blocking device.
Restore the current and tripping circuits of the 7SJ62/63/64 and the feeder relays.
3.3.8 Directional Checks with Load Current
Load Current≥ 10 % IN
The connections of the current and voltage transformers are checked using load cur-rent on the protected line. The secondary load current must be at least 0.10 · IN. Theload current should be in-phase or lagging the voltage (resistive or resistive-inductiveload). The direction of the load current must be known. If there is a doubt, networkloops should be opened or other action taken to guarantee the direction of the loadcurrent. The line remains energized during this directional test.
DThe direction can be derived directly from the operational measured values. Initiallythe correlation of the measured load direction with the actual direction of load flow ischecked. In this case the normal situation is assumed whereby the forward direction(measuring direction) extends from the busbar towards the line (Figure 3-35).
P positive, if active power flows into the line,
P negative, if active power flows towards the busbar,
Q positive, if reactive power flows into the line,
Q negative, if reactive power flows toward the busbar.

Installation and Commissioning
The power measurement provides an initial indication as to whether the measured val-ues have the correct polarity. If both the active power as well as the reactive powerhave the wrong sign, the polarity in addresse 0201 CT Starpoint must be checkedand rectified.
However, energy metering itself is not able to detect all connection errors. For this rea-son, directional messages should be generated by means of the directional overcur-rent protection. The 67-TOC element is used to generate directional messages. Thepickup threshold of 67-TOC, approximately [1.1 · Address 1507 67-TOC PICKUP],must be reduced so that the available load current causes a continuous pickup of theelement. The direction reported in the messages, such as “Phase A forward“ or„Phase A reverse“ must correspond to the actual power flow. While performing thistest and interpreting the results, be careful that the “Forward” direction of 67-TOC isin the direction of the line (or object to be protected). This is not necessarily identicalwith the direction of the normal network current flow or the load current flow for thistest. For all three phases, the corresponding power flow directional messages must bereported properly.
If all directions are incorrect, then there is conflict between the polarity of the currenttransformers and the polarity set under Address 0201 CT Starpoint, in P.System Data1. The polarity of the current transformers must be determined and properly setin the 7SJ62/63/64 according to Subsection 2.1.3. If the directional data are diverse,then individual phases in the current or voltage connections are interchanged, or thephase sequence is not correct. The connections must be checked and corrected. Fi-nally the phase is again de-energized.
Note! Set the pickup values that have been changed for testing back to the valid set-tings!
3.3.9 Polarity check for the voltage input U4 (only 7SJ64)
Depending on the application of the voltage measuring input U4 of a 7SJ64, a polaritycheck may be necessary. If no measuring voltage is connected to this input, this sub-section is irrelevant.
If the input U4 is used for measuring the displacement voltage Uen (power system data1 address 0213 VT Connection = Van,Vbn,Vcn,VGn or Vab, Vbc, VGnd), thepolarity is checked together with the measured current test according to Subsection3.3.11.
Only for Synchro-nism Check in7SJ64
If the input U4 is used for measuring a voltage for synchronism check (power systemdata 1 address 0213 VT Connection = Van,Vbn,Vcn,VSy , observe the following:
• The single-phase voltage U2 to be synchronized must be connected to the input U4;
• The polarity must be checked as follows using the synchronism check function:
The device must be equipped with the synchronism and voltage check. For verifyingthe synchrocheck function at address 016x, SYNC Funktion xmust be configuredto SYNCHROCHECK (refer to Subsection 2.1.1).
The voltage U2 to be synchronized must be specified correctly under address 6X23 CONNECTIONof V2 (refer to Subsection 2.16.2).
334 7SJ62/63/64 ManualC53000-G1140-C147–1
Commissioning
If a transformer is located between the measuring points of reference voltage U1 andthe voltage to be synchronized U2, the angle must correspond to the phase rotationthrough which the vector group of the transformer as seen from the feeder in the di-rection of the busbar rotates the voltage. For this purpose an angle corresponding tothe transformer vector group is entered in address 6X22 ANGLE ADJUSTM. An ex-ample is shown in Subsection 2.16.2 gegeben.
If necessary different transformation ratios of the voltage transformers on the busbarand the feeder may have to be considered under address ON under address 6X01Synchronizing X.
A further aid for checking in the connection are the messages 170.2090 “25 V2>V1“,170.2091 “25 V2<V1“, 170.2094 “25 a2>a1“ and 170.2095 “25 a2<a1“ in thespontaneous annunciations.
Circuit breaker is open. The feeder is isolated (zero voltage). The VTmcbs of bothvoltage transformer circuits must be closed.
The program Direct CO = YES (address 6X10A) must be set for the synchro-check; the other programs (addresses 6X07 to 6X09) are set to NO.
A request for synchro-check is initiated via binary input (FNo. 170.0043 “>25 Measu. Only“). The synchro-check must give close release (message “25 Clos-eRelease“, FNr 170.0049). If not, check all relevant parameters again (synchro-check configured and switched on correctly, see sections 2.1.1 and 2.16.2).
Set address 6X10 Direct CO to NO.
Then the circuit breaker is closed while the line isolator is open (see Figure 3-36).Both voltage transformers therefore measure the same voltage.
The program SYNC-Funktionsgruppe X = ASYN/SYNCHRON (Adresse 016X) isset.
A request for synchro-check measurement is initiated via binary input (FNo.170.0043 “>25 Measu. Only“). The synchro-check must give close release(message “25 CloseRelease“, FNo 170.0049).

3.3.10 Ground Fault Check in a Non-Grounded System
The ground fault check is only necessary if the device is connected to an isolated orresonant-grounded system and the ground fault detection is applied. The device musttherefore be provided with the ground fault detection function according to its ordering

code (position 15 in ordering code: D or B or F or H). Furthermore, address 0131Sens. Gnd Fault = Enabledmust have been preset during configuration to enablethis function (according to Subsction 2.1.1). If none of this is the case, Subsection3.3.10 is not relevant.
The primary check serves to find out the correct polarity of the transformer connec-tions for the determination of the earth fault direction.
Using the primary earth fault method a most reliable test result is guaranteed. There-fore please proceed as follows:
Isolate the line and earth it on both ends. During the whole testing procedure theline must be open at the remote end.
Make a test connection between a single phase and ground. On overhead lines itcan be connected anywhere, however, it must be located behind the current trans-formers (looking from the busbar of the feeder to be checked). Cables are earthedon the remote end (sealing end).
Remove the protective earthing of the line.
Connect a circuit breaker to the line end that is to be checked.
Check the direction indication (LED if allocated)
The faulty phase (FNo 01272 for L1 or 01273 for L2 or 01274 for L3) and the di-rection of the line, i.e. “SensGnd Forward“ (FNo 01276) must be displayed in theearth fault protocol.
The active and reactive components of the earth current are also displayed. The re-active current (“INs Reac“, FNo 000702) is the most relevant for isolated systems,for resonant-earthed systems it is the active current (“INs Real“, FNo 000701). Ifthe display shows the message “SensGnd Reverse“ (FNo 01277), either the cur-rent or voltage transformer terminals are swopped in the neutral path. In case themessage “SensGnd undef.“ (FNo 01278) appears the earth current may be toolow.
Deenergize and earth the line.
The check is then finished.
3.3.11 Polarity Check for the Current Measuring Input IN
If the standard connection of the device is used whereby the current measuring inputIN is connected in the star-point of the set of current transformers (refer also to the con-nection circuit diagrams in the Appendix A.3, Figure A-45, A-55, then the correct po-larity of the earth current path in general will result automatically.
DANGER!Primary measurements must only be carried out on disconnected and groundedequipment of the power system. Danger to life exists even on disconnectedequipment because of capacitive coupling from other energized equipment ofthe power system!
3377SJ62/63/64 ManualC53000-G1140-C147–1
Installation and Commissioning
If however the current IN is derived from a separate summation CT (e.g. a core bal-ance CT, see Section A.3, Figure A-47, A-57, A-64) an additional polarity check withthis current is necessary.
If the device is provided with the sensitive current measuring input IN and it is connect-ed to an isolated or resonant-grounded system, the polarity check for IN was alreadycarried out with the earth fault check according to 3.3.10. Then this Subsection 3.3.11can be ignored.
Otherwise the test is done with a disconnected trip circuit and primary load current. Itmust be noted that during all simulations that do not exactly correspond with situationsthat may occur in practice, the non-symmetry of measured values may cause themeasured value monitoring to pick up. This must therefore be ignored during suchtests.
Directional Testingfor a Grounded Net-work
The check can either be carried out with function “directional ground fault protection”(address 0116) or function “ground fault detection” (address 0131), which can be op-erated as additional short-circuit protection.
In the following the check is described using the “directional ground fault protection”function (address 0116) as an example.
To establish 3V0 (a displacement voltage), the connection of one VT winding is re-moved from the device. In Figure 3-37, the open delta VTs are modified so that onlyVb and Vc are connected to the inputs Ve-n of the device. Alternatively, Va from thewye-VTs can be disconnected. If no connection for VNs (Ve-n connection) is foreseen,the secondary side of the corresponding phase can be disconnected as shown in Fig-ure 3-38. The device receives only the current from the phase where the associatedvoltage connection at the device is missing. If the line current is in-phase or laggingthe voltage (resistive or resistive-inductive load), the same current-voltage relation-ships exist for the device in this test simulation as during a phase-ground fault in thedirection of the line.
At least one stage of the ground fault protection must be set to be directional. The pick-up threshold of this stages must be below the load current flowing on the line; if nec-essary the pick-up threshold must be reduced. The parameters that have beenchanged must be noted.
After switching the line on and off again, the direction indication must be checked: inthe fault messages the messages “67N picked up“ and „Ground forward“ mustat least be present. If the directional pick up is not present, either the earth current con-nection or the displacement voltage connection is incorrect. If the wrong direction isindicated, either the direction of load flow is from the line toward the busbar or theearth current path has a swapped polarity. In the latter case, the connection must berectified after the line has been isolated and the current transformers short-circuited.
In the event that the pick-up alarms were not even generated, the measured earth (re-sidual) current or the displacement voltage evolved may be too small. This can be che-cked by means of the operational measured values.
DANGER!Working on measurement transformers requires the highest precautions!Short-circuit current transformers before any current connections to the deviceare opened!

3.3.13 Measuring the operating time of the circuit breaker (only 7SJ64)
Only forSynchronismCheck
If the device 7SJ64 is equipped with the function for synchronism and voltage checkand it is applied, it is necessary — under asynchronous system conditions — that theoperating time of the circuit breaker is measured and set correctly when closing. If thesynchronism check function is not used or only for closing under synchronous systemconditions, this subsection is irrelevant.
For measuring the operating time a setup as shown in figure 3-39. The timer is set to1 s and a graduation of 1 ms.
The circuit breaker is closed manually. At the same time the timer is started. After clos-ing the poles of the circuit breaker, the voltage UFeeder appears and the timer isstopped. The time displayed by the timer is the real circuit breaker closing time.
If the timer is not stopped due to an unfavourable closing moment, the attempt will berepeated.
It is particularly favourable to calculate the mean from several (3 to 5) successfulswitching attempts.
Set the calculated time under address 6X20 as T-CB close (under power systemdata 2). Select the next lower adjustable value.

information of the circuit breaker position injected via binary inputs is read out at thedevice and compared with the actual breaker position. For devices with graphic dis-play this is easy to do with the control display.
The switching procedure is described in the SIPROTEC® 4–System Manual. Theswitching authority must be set in correspondence with the source of commands used.The switching mode can be selected from interlocked and non-interlocked switching.Please take note that non-interlocked switching can be a safety hazard.
Control by Protec-tive Function
Tripping of the primary equipment by protective elements can be verified if desired.However, be fully aware that such testing can result in closing of the circuit breaker bythe reclosing element in the 7SJ62/63/64 or an external reclosing device. If circuitbreaker closing is to be avoided, be sure the closing is defeated before the test is per-formed. If reclosing is desired, select an element in the 7SJ62/63/64 that initiates re-closing, and test the control by tripping this element in the testing. To avoid a trip-close-trip event, be sure the protective element is dropped out before the close occurs.
Control from a Re-mote Control Cen-tre
If the device is connected to a remote substation via a system (SCADA) interface, thecorresponding switching tests may also be checked from the substation. Please alsotake into consideration that the switching authority is set in correspondence with thesource of commands used.
3.3.15 Triggering Oscillographic Recordings
At the end of commissioning, an investigation of switching operations of the circuitbreaker(s) or primary switching device(s), under load conditions, should be done toassure the stability of the protection during the dynamic processes. Oscillographic re-cordings obtain the maximum information about the behaviour of the 7SJ62/63/64.
Requirements Along with the capability of recording waveform data during system faults, the 7SJ62/63/64 also has the capability of capturing the same data when commands are givento the device via the service program DIGSI® 4, the serial interfaces, or a binary input.For the latter, the binary input must be assigned to the function “>Trig.Wave.Cap.”(FNo 00004). Triggering for the oscillographic recording then occurs when the input isenergized. For example, an auxiliary contact of the circuit breaker or control switchmay be used to control the binary input for triggering.
An oscillographic recording that is externally triggered (that is, without a protective el-ement pick-up or device trip) is processed by the device as a normal fault recordingwith the exception that data are not given in the fault messages (trip log). The exter-nally triggered record has a number for establishing a sequence.
DANGER!A successfully started test cycle can lead to the closing of the circuit breaker!

3.4 Final Preparation of the Device
Tighten the used screws at the terminals; those ones not being used should be slightlyfastened. Ensure all pin connectors are properly inserted.
Verify that all service settings are correct. This is a crucial step because somesetting changes might have been made during commissioning. The protectivesettings under device configuration, input/output configuration are especially impor-tant (Section 2.1.1) as well as the power system data, and activated Groups A throughD (if applicable). All desired elements and functions must be set ON. See Chapter 2.Keep a copy of all of the in-service settings on a PC.
Check the internal clock of the device. If necessary, set the clock or synchronize theclock if it is not automatically synchronized. For assistance, refer to the SIPROTEC®
4 System Manual.
The Annunciation memory buffers should be cleared, particularly the Event Log andTrip Log. Future information will then only apply for actual system events and faults.To clear the buffers, press MAIN MENU → Annunciation → Set/Reset. The num-bers in the switching statistics should be reset to the values that were existing prior tothe testing, or to values in accordance with the user's practices. Set the statistics bypressing MAIN MENU → Annunciation → Statistic. Refer to the SIPROTEC® 4System Manual if more information is needed.
Press the key, several times if necessary, to return to the default display.
Clear the LEDs on the front panel by pressing the key. Any output relays that werepicked up prior to clearing the LEDs are reset when the clearing action is performed.Future indications of the LEDs will then apply only for actual events or faults. Pressingthe key also serves as a test for the LEDs because they should all light when thebutton is pushed. Any LEDs that are lit after the clearing attempt are displaying actualconditions.
The green “RUN” LED must be on. The red “ERROR” LED must not be lit.
Close the protective switches. If test switches are available, then these must be in theoperating position.
The device is now ready for operation.
Caution!
Do not use force! The tightening torques must not be exceeded as the threads andterminal chambers may otherwise be damaged!

CONDENSATION MUST BE AVOIDED
Siemens recommends that all devices be installed such that they are not exposed todirect sunlight, nor subject to large fluctuations in temperature that may cause conden-sation to occur.
4.1.8 Service Conditions
The protective device is designed for use in an industrial environment and an electricalutility environment. Proper installation procedures should be followed to ensure elec-tromagnetic compatibility (EMC). In addition, the following are recommended:
• All contacts and relays that operate in the same cubicle, cabinet, or relay panel asthe numerical protective device should, as a rule, be equipped with suitable surgesuppression components.
• For substations with operating voltages of 100 kV and above, all external cablesshould be shielded with a conductive shield grounded at both ends. The shield mustbe capable of carrying the fault currents that could occur. For substations with loweroperating voltages, no special measures are normally required.
356 7SJ62/63/64 ManualC53000–G1140–C147–1
General Device Data
• Do not withdraw or insert individual modules while the protective device is ener-gized. When handling the modules or the device outside of the case, standards forcomponents sensitive to electrostatic discharge (ESD) must be observed. The mod-ules and device are not endangered when inserted into the case.

Notes:4) for isolated/compensated networks, only for sensitive ground current transformer if 7th digit = 2, 6.5) only for non-sensitive ground current transformer if 7th digit = 1, 5, 7.
Comment (applies for all device versions 7SJ62/63/64)1) if the optical interface is required you must order the following: 11th digit = 4 (RS485)
and in addition:
for single ring: SIEMENS OLM 6GK1502–3AB10for double ring: SIEMENS OLM 6GK1502–4AB10
The converter requires an operating voltage of 24 V DC. If the available operating voltage is> 24 V DC the additional power supply 7XV5810–0BA00 is required.
3) if you want to run the RTD-Box at an optical interface, you need also theRS485–FO–converter 7XV5650–0*A00 (see Accessories at A.1.6).

Note: The following table lists all data which are available in the maximum complement of the devices. Depen-dent on the ordered model, only those data may be present which are valid for the individual version. In the listbelow, the setting ranges and default setting values for the pickup currents are for a device with a nominal cur-rent rating IN = 1 A. For a nominal current rating IN = 5 A, multiply the Setting Options values and Default Settingvalues by 5. Consider the current transformer ratios when setting the device with primary values.
Addresses to which the letter “A“ is attached can only be modified by using the DIGSI® 4 software at “FurtherSettings“.

A.10 Information List
A.10 Information List
NOTE: The following table lists all data which are available in the maximum complement of the device. Depen-dent on the ordered model, only those data may be present which are valid for the individual version.
The symbol ’ > ’ indicates that the source of the indication is a binary input.
Indications for T103 are always reported ON / OFF if they are subject to general interrogation forIEC 60870-5-103. If not, they are reported only as ON.
New user-defined indications or such newly allocated to IEC 60870-5-103 are set to ON / OFF and subjectedto general interrogation if the information type is not a spontaneous event (".._Ev").
In columns “Event Log”, “Trip Log” and “Ground Fault Log” the following applies:
UPPER CASE: ON/OFF definitely set, not allocatablelower case: preset, allocatable*: not preset, allocatable<blank>: neither preset nor allocatable
O/O – ON / OFF DP – Double Point Indication
OUT – Output Indication C – Command without feedback
SP – Single Point Indication CF – Command with Feedback
IntSP – Internal Single Point Indication MV – Measured Value
