APPLICATION
The MiCOM P740 numerical busbar protection schemehas been designed to protect a wide range of busbarconfigurations. The modular scheme utilises threerelay types:
• Central Unit (CU) - P741
• Peripheral Unit (PU) - P742 / P743These units interconnect using fibre optic cables andtogether with the topology configurator software, allowapplication to all types of busbar configuration.
The Central Unit co-ordinates the scheme, receivingsignals from all the peripheral units associated with theprotected busbars and acting on these signals, initiatesa buszone protection trip when necessary. A singleCentral Unit can accommodate up to,
• 8 Zones
• 28 Peripheral Units
One Peripheral Unit is associated with each CT location, usually one per incomer/feeder and oneor two for each bus coupler/bus section, depending onthe number of CTs. The Peripheral Units acquire theanalogue signals from the associated CT and thebinary signals from the auxiliary contacts of the circuitbreakers and isolators. The Peripheral Units alsoincorporate the main circuit breaker failure logictogether with additional protection functions (Deadzone, overcurrent, etc.).
The P743 allows for increased opto inputs, functionkeys and ethernet board option and is particularlyuseful in double busbar applications. Additionally,where single pole breakers and transfer busbars areemployed, the I/O requirements are large incomparison to those required for a single busbarapplication, where a P742 may be more suitable.

FUNCTIONAL OVERVIEW
(Description of ANSI code nos. see Protection Function Overview)
The P740 employs biased differential algorithms, inwhich the differential current is compared with a biascurrent. This characteristic ensures stability of theprotection for external faults even with differing CTtolerance and errors which could lead to spuriousoperation.
To increase the security of the differential protection,the biased differential element is supervised by abiased global check zone element. This ensuresstability even under erroneous status of the auxiliarycontact of plant isolators and circuit breakers.
The MiCOM P740 also employs CT supervision andan innovative, ultra high-speed, secure CT saturationdetection algorithm. This ensures stability when CTsbecome saturated, particularly under external faultconditions. This algorithm combines a simulation of the flux built up in the core of the CTs with a recursiveconsistence variation control. This technique candetect CT saturation in less than 2ms.

Bias differential characteristics
CT saturation detection
To ensure adaptability of the relay to any type ofbusbar configuration the P740 is built with a universaltopology processing algorithm. This algorithmdetermines the optimum tripping zone based on the current status of the plant isolators and circuitbreakers.
BUSBAR DIFFERENTIAL PROTECTION
The primary protection element of the P740 scheme is the phase segregated biased current differentialprotection. The technique is based on the numericalapplication of Kirchoff's Law for the selective detectionand ultra high-speed isolation of a faulty section of the busbar.
The analysis is carried out in the Central Unit (CU)which communicates with the Peripheral Unit (PU)to gather current information from individual circuits and to implement the tripping of circuits as required This reliable, high speed communication is achieved via a direct optical connection utilising a 2.5 Mbps data rate.

DUAL CHARACTERISTICS
To provide stability for severe through faults and at thesame time detect low current internal faults, the P740is equipped with dual characteristics. One phasesegregated differential protection and anothersensitive earth current differential protection.
MULTIPLE TRIPPING CRITERIA
The MiCOM P740 maintains the highest level ofstability under all conditions including hardwarefailure and incoherent signals applied from externalplant or generated by the power system. Any tripping order must therefore be made conditionalon the simultaneous occurrence of 7 to 9 criteria:
> Magnitude criteria; confirmation of two simultaneousthresholds per zone:• Exceeding the bias slope characteristic (k2)• Exceeding differential operating current threshold
(ID>2).> Check zone supervision
The zone element(s) are only permitted to trip if theorder is confirmed by the check zone element:• Exceeding the bias slope characteristic (kCZ)• Exceeding differential operating current threshold
(IDCZ>2)> Signal quality criteria:
• No CT saturation detected• Current variation detected on at least two
Peripheral Units (except for dead bus)> Time or angular criterion.
The measurement elements on 2 samples taken at1200 Hz. A first sample for the initial measurementand a second sample for trip confirmation.
> Local criteria (optional)The Peripheral Units can be set to only authorisetripping if there is confirmation by local overcurrentcriteria or undervoltage or zero sequenceovervoltage.
DEAD ZONE OR BLIND SPOT PROTECTION
The current transformers or the open breakerssurrounding the busbars define the limits of the mainzones. When a feeder circuit breaker is opened a deadzone or blind spot is created between the CB and the associated CT. The Peripheral Unit detects thiscondition automatically and provides protection for this zone also.One stage of definite time delayed overcurrent andearth fault protection is provided in each PeripheralUnit to provide this functionality
CONTINUOUS SUPERVISION OF CURRENT CIRCUITS
The P740 detects any abnormality in the current circuitby continuously monitoring it. Under normal operatingconditions the differential current will be negligible. Ananomaly is detected by a threshold, ID>1, which canbe set to alarm from 10 A primary.
DIFFERENTIAL CURRENT SETTING
When switching operations are carried out in thesubstation, incorrect topology replicas may occur. Inthis case, a differential current appears. The differentialelements of the MiCOM P740 are allowed to operateonly if the differential current reaches a threshold ID>2which is normally set above the highest load current.
ADDITIONAL ULTRA HIGH SPEEDEXTERNAL FAULT BLOCKING
Ultra high-speed through fault detection can be carriedout in each PU and can generate a control signal fromthe moment of the first sample (0.4 ms) to block theconnected zone before CT saturation.

PHASE OVERCURRENT AND EARTH FAULT PROTECTION
Two independent stages of phase overcurrent andearth fault protection is provided in the Peripheral Units.These elements provide additional protection for theindividual circuits. The two stages can be programmed as:
> First stage can be programmed as definite time (DT)delay or one of the nine inverse time (IDMT) curves(IEC/UK and IEEE/US).
> Second stage can only be programmed as definitetime.
CIRCUIT BREAKER FAILURE PROTECTION (LBB)
The P740 offers an in-built integrated solution forbreaker failure protection. This requires all PeripheralUnits to receive a duplication of the trip commandsgenerated in their associated bay. In general the Breaker Failure protection is executed ona per phase basis which involves the possibility ofreceiving tripping orders on a per pole basis.
The MiCOM P740 busbar protection scheme can alsowork in co-ordination with external breaker failureprotection relays. In this configuration, the receipt of an external breaker failure command results in trippingof all the adjacent circuit breakers, via the topologicalrecognition system knowing which breaker is connectedto which zone.
CURRENT TRANSFORMERMIXING CORRECTION
The MiCOM P740 can correct a mix between currenttransformer ratios over a very wide range up to 40. Its associated user interface provides a range between1 A and 30 000 A primary.
Since the current transformer ratings in a substationmay be of mixed ratios, the MiCOM P741 uses avirtual CT ratio equal to 1000/1, irrespective of thefeeder section concerned.
ISOLATION AND MAINTENANCEOPERATING MODE
For ease of operation or maintenance of the busbarprotection system, the Central Unit and the PeripheralUnits can receive specific commands designed toallow system testing or other intervention without anydanger of unwanted tripping.In the Central Unit, a centralised command to isolatethe busbars at two levels can be selectively applied perzone:
> Differential protection (87BB) blocked (measurementsactive and 87BB tripping deactivated).The Breaker Failure protection (50BF) remainsoperational.
> Differential protection (87BB) and Circuit BreakerFailure protection (50BF) blocked.The additional local protection functions(51, 51N, etc...) remain operational.
All the protections in the CU and the PUs (87BB, DeadZone, General 50BF, Local 50BF, O/C, etc…) can bealso blocked.
A selective two-level command may be appliedselectively for each Peripheral Units:
> Intervention on another bay protection formaintenance and testing:The local Breaker Failure protection (50BF) is blocked but the busbar protection remains in service.. PU in 50BF blocked mode
> Intervention on the PU for maintenance and testing:PU in Overhaul mode
PROGRAMMABLE SCHEME LOGIC
Powerful programmable scheme logic (PSL) allows theuser to customize the protection and control functions.It is also used to programme the functionality of theoptically isolated inputs, relay outputs and LEDindications (red or tri-colour). The programmablescheme logic comprises of gate logic and generalpurpose timers. The gate logic includes OR, AND andmajority gate functions, with the ability to invert theinputs and outputs, and provide feedback. Theprogrammable scheme logic is configured using thegraphical MiCOM S1 PC based support software.
PLANT STATUS AND MONITORING
Checks and monitoring of the plant status can bemade and an alarm raised for any discrepancycondition between the open and closed auxiliarycontacts of the isolators and circuit breakers. The Dynamic Synoptic software allows the user tomonitor the position of CBs and isolators in the busbarscheme, as well as currents, alarms, etc...
MEASUREMENT AND RECORDING FACILITIES
The P740 series relays are capable of measuring and storing the values associated with a fault. All theevents, faults records and disturbance records are timetagged to 1 ms using an internal real time clock. Anoptional IRIG-B port is also provided for accurate timesynchronization. A lithium battery provides a back upfor the real time clock and all records in the event ofsupply failure.
MEASUREMENTS
The measurements provided, which may be viewed in primary or secondary values, can be accessed via the back lit liquid crystal display. They are alsoaccessible via the communication ports. The followinginstantaneous parameters can be viewed:
> Central unit (P741)• Differential current Idiff / phase / zone• Bias current Ibias / phase / zone• Check zone Idiff / phase
> Peripheral units (P742 & P743)• Phase currents IA IB IC• Neutral current IN• Sequence currents• Frequency
EVENT RECORDER
Up to 512 time tagged event records are stored inbattery backed memory, and can be extracted via thecommunication port or be viewed on the front paneldisplay.
FAULT RECORDER
Records of the last 5 faults are stored in the battery-backed memory of both the Central andPeripheral Units.
Each fault record includes:
> Indication of the faulty zone (CU + PU)
> Protection element operated
> Active setting group
> Fault duration
> Currents and frequency (PU)
> Faulty zone differential and bias current (CU)
> Topology at the fault occurence
DISTURBANCE RECORDER
The Central and Peripheral units of the P740 haveindependent disturbance recording facility. ThePeripheral Units can record 4 analogue and 32 digitalchannels, whereas the Central unit stores 8 analogueand 32 digital channels in addition to 1 time channel.
> Specific analogue channels• Check zone Ibias / Idiff (CU)• IA, IB, IC, IN (PU)
> Maximum duration of one record and number of records • 1.2s per record and 8 records (CU)• up to 10.5s per record and minimum of
50 records 1.5s (PU)
Disturbance records can be extracted from the relayvia the remote communications and saved in theCOMTRADE format. These records may be examinedusing MiCOM S1 or any other standard COMTRADEviewer.

LOCAL AND REMOTE COMMUNICATIONS
Two communication ports are available as standard; a rearport providing remote communications and a front portproviding local communications. As option an Ethernet boardcan be added in the P741 and P743s to use the IEC61850-8-1protocol.
The front RS232 port has been designed for use withMiCOM S1, which fully supports functions within the relay by providing the ability to programme the settings off-line,configure the programmable scheme logic, extract and viewevent, disturbance and fault records, view the measurementinformation dynamically and perform control functions (using Courier protocol).
The default remote communications is Courier / RS 485 orK-bus and can be converted to IEC60870-5-103.
IEC 61850 is available when the optional Ethernet port is ordered. IEC 61850 offers high-speed data exchange, peer-to-peer communication, reporting, disturbance recordextraction and time synchronization.
DIAGNOSTICS
Automatic tests performed including power-on diagnostics andcontinuous self-monitoring ensures a high degree of reliability.The results of the self-test functions are stored in batterybacked memory. Test features available on the user interfaceprovide examination of input quantities, states of the digitalinputs and relay outputs. A local monitor port provides digitaloutputs, selected from a prescribed list of signals, including the status of protection elements.

MiCOM P743 case 60TE – Peripheral Unit
P740 Technical Data Sheet EN 25 P740/EN TDS/K55
MICOM P740 GUIDE FORM SPECIFICATION
The differential busbar protection has to be of entirely numerical technology and allow a centralised or distributed architecture via fibre optic communication. The distance between the acquisition (feeder) unit and the measurement unit must be able to reach 1000 metres.
The protection will include differential elements with phase segregation, biased check zone elements and a separate sensitive earth fault element for networks with high impedance earthing.
The sensitive earth fault element will be controlled by through current to guarantee its stability on external faults and in the presence of significant errors in measurement transducers (CTs).
Protection must have a low burden to enable it to be installed in series with other equipment on common secondary cores of the current transformers.
It has to allow the use of different class and type of CTs made by different manufacturers. In particular, it will have to be able to accept mixes of plant, satisfying different standards (e.g. British Standard 3938: Class X, IEC 185: Class 5P20, IEC 44-6 Class TPX, TPY or TPZ).
Owing to these various standards, calculation algorithms have to provide an effective compensation for transitory errors of amplitude and phase from the CTs in presence of a strong continuous dc component in the short-circuit current.
The protection has to be stable for all types of external faults and in particular under CT saturation conditions. This saturation has to be able to be detected in less than 2 ms.
In addition to signal processing algorithms for the detection of saturation, it will be able to be activated for very low rated feeders equipped with low ratio CTs, a fault criterion able to provide information of an external short-circuit in a time which does not exceed 0.5 ms.
The topological processing algorithms have to allow for the dynamic consideration of primary plant position changes in a period which does not exceed 30 ms for complex architectures going up to 8 zones and 28 Peripheral Units.
A peripheral unit must be capable of monitoring one breaker and six isolators.
The trip decision for the busbar zone has to comply with multiple criteria at the top level (i.e. in the Central Unit) and additional criterion at local level (i.e. in the Peripheral Unit).
One of the criteria has to be such that the system cannot be permitted to operate on a significant load current in a zone
temporarily or incorrectly opened by the topological analysis algorithm.
The differential busbar protection has to implement also an effective protection against circuit breaker failures.
Each peripheral unit will be equipped with local circuit breaker failure. When such a condition is initiated all the circuit breakers adjacent to the faulty circuit breaker will be identified and tripped selectively by way of the scheme topology and via the busbar differential protection.
The circuit breaker failure sequence has to include a re-trip, which can be initiated via another protection on the same circuit i.e. for the same circuit breaker. This sequence must be user configurable and either instantaneous or time delayed.
On overhead lines where single-pole tripping will be carried out, monitoring has to be carried out on a per phase basis.
The open circuit breaker poles will be checked by means of an under current detector and by monitoring auxiliary contact positions.
To avoid all risk of maloperation during work on the LV protection circuits that communicate with the circuit breaker failure controller, a local criterion can be activated in order to permit only a tripping instruction to the central unit in the event of a fault on the feeder concerned.
Maintenance and testing must be able to be conducted safely by means of control via several levels of isolation.
In particular, it will have to be possible, without interfering with wiring, to configure the system in the following reduced modes of operation:
> Monitoring Mode – differential element de-activated, tripping prohibited but measurements still active.
> Complete isolation of the central functions with the local functions remaining operational.
> Local isolation of a peripheral unit without affecting the rest of the system.
Time tagged events, faults and disturbance records must be saved in battery backed memory. The internal disturbance recorder shall have a capacity to store 20 records, each record shall store data from 8 analogue channels and 32 digital channels.
It must be possible, using a graphical PC based software to monitor the plant status: • Position of CBs and isolators in the busbar scheme, • Differential and bias currents of all the zones & CZ, • Alarms (raised for any discrepancy condition between the
open and closed auxiliary contacts of the isolators and circuit breakers, CT failure, etc…).
The protocol IEC61850-8-1 must be available through a copper and fibre optic Ethernet communication ports
