DescriptionGeneral

3AD vacuum reclosers are outdoor circuit-breakers

designed for frequent opening and reclosing in case of

temporary faults. They fulfill this task automatically by

monitoring the line and operating autonomously.

The recloser consists of two main components: The

switch unit being the circuit-breaker and the controller as

protection and control unit. It is housed inside the control

cubicle.

Recloser principle

Reclosers are used in distribution systems of power supply

companies (utilities). Like circuit-breakers they are capable

of switching normal and fault currents. They are equipped

with sensors and a controller being the protection and

control device. In case of a line fault, they can break and

make several times, thus avoiding longer network interrup-tions due to temporary faults.

As outdoor devices they are normally pole-mounted and

exposed to environment and weather. A recloser consists of

two components: The switch unit (circuit-breaker) and the

controller (inside the control cubicle), both connected

through a control cable.

Design

Switching operation

The vacuum switching technology, proven and fully

developed for more than 30 years, is the basis for the

vacuum interrupters.

Pole assemblies

Each vacuum interrupter is embedded in an epoxy-resin pole

made out of weather-proof cycloalyphatic resin. This enables

a small design as well as resistance against environmental

effects. The vacuum interrupter is vertically mounted inside

the pole, providing a long service life. Each recloser is equip-

ped with an integrated current transformer. For special pro-

tection purposes, a resistive voltage sensor can also be

incorporated in the pole. The accuracy achieved in this way

is much higher than that of capacitive dividers.

Operating mechanism

The pole assemblies of the recloser are directly mounted on

the operating mechanism housing. Besides the complete

kinematics, it also accommodates the position indicator and

a mechanical operations counter. The operating mechanism

housing is made of mild steel with a special coating for out-

door applications. Optionally, a stainless-steel housing is

available.

Siemens Vacuum Recloser 3ADDescriptionSwitch unit

Mechanical lockout

A mechanical lockout enables tripping independently on the

controller. If this handle is pulled, the recloser opens and is

simultaneously locked out electrically and mechanically. The

handle stays extended, thus indicating the interlocked state.

To close the recloser again, the operating rod must first be

pushed back to the operation position in order to release the

lockout. Then the recloser can be closed electrically via the

control.

Recloser cycle

In case of a network fault, the recloser opens and recloses

several times. In case of temporary faults the automatic

reclosing significantly reduces the loss of power supply.

The recloser cycle is optimized accordingly:

The first interruption of a fault is done quickly and

instantaneously, so that even the fuses in the system do not

operate. After approx. 300 ms (user settable), it recloses

back on.

The second and third interruption has a definite or inverse-

time delay. Thus, downstream fuses in the network have the

chance to operate and isolate the affected network section,

restoring normal operation in the remaining network. The

following dead time is usually 210 s (user settable).

The fourth (optional up to the fifth) interruption is fast

again and serves as a check. This for example utilizes the

physical effect that, when the short-circuit occurs, the lines

move due to the magnetic forces of the current, and foreign

objects are shaken off.

If the fault still exists, the recloser turns to the lockout and

can only be closed from the operator panel or via SCADA.

The controller

The Siemens Argus-M controller is based on the Argus-M

directional overcurrent protection relay. These relays provide

protection, control, monitoring, instrumentation and me-

tering with integrated input and output logic, data logging

& fault reports.

Communication access to relay functionality is via a front

USB port for local PC connection or a rear electrical RS485

port for remote connection. Additional rear port options are

available.

The controller is mounted in the control cubicle. Along with

the controller, this cubicle also contains the auxiliary power

supply with batteries for uninterruptible power supply,

electronic boards, fuses, and a general-purpose outlet to

power a laptop.The controller contains a large number of protection

functions (elements) which can be selected or deselected

through the menu driven display. These elements can be

customized to the utilities needs by parameters (settings) as

described below.

8 or 16 programmable tri-color LEDs are available

eliminating the need for expensive panel-mounted pilot

lights and associated wiring. Each LED is tri-colored (red,

green, yellow) allowing for clear indication of the associated

functions state.

12 programmable function keys each with tri-color LED are

available for implementing scheme control functionality.

Each function key has an associated tri-color LED (red,

Protection functions

(in order of ANSI numbering)

37 Undercurrent

Each element has settings for pickup level and Definite Time

Lag (DTL) delays. Operates if current falls below setting for

duration of delay.

46BC Broken conductor/phase unbalance

Element has settings for pickup level and DTL delay. With the

circuit-breaker closed, if one or two of the line currents fall

below setting, this could be due to a broken conductor.

46NPS Negative phase-sequence overcurrent

Each element has user settings for pickup level and Inverse

Definite Minimum Time Lag (IDMTL) or DTL delay. It operates

if NPS current exceeds setting and delay. NPS current ele-ments can be used to detect unbalances on the system or

remote earth faults when a delta-star transformer is in

circuit.

49 Thermal overload

The thermal algorithm calculates the thermal states from the

measured currents and can be applied to lines, cables and

transformers. Outputs are available for thermal overload and

thermal capacity.

50/51 Phase fault

50 INST (instantaneous)/DTL (Definite Time Lag) and

51 IDMTL (Inverse Definite Minimum Time Lag)/DTL ele-

ments provide overcurrent protection, each with indepen-

dent settings for pickup current, time-multiplier (51) and

time delays. The user can select IEC or ANSI time current

characteristics. The IDMT stage has a user programmable

reset characteristic, either DTL or shaped current/time resetcharacteristic to improve grading with electromechanical

protection.

50G/51G/50N/51N Earth fault/sensitive earth fault

Earth-fault current is derived from the residual connection of

the 3 integrated line CTs 50 INST/DTL and 51 IDMTL/DTL

64H Restricted earth-fault scheme

The measured earth-fault input may be used in a 64H high

impedance restricted earth-fault scheme. Required external

series stabilizing resistor and non-linear shunt resistor can be

supplied.

74TC Trip-circuit supervisionThe trip-circuit(s) can be monitored via binary inputs. Trip-

circuit failure raises an HMI alarm and output(s).

81HBL2 Inrush restrain/second harmonic block

Where second harmonic current is detected (i.e. during

transformer energization) user selectable elements can be

blocked.

Cold load pickup

If a circuit-breaker is closed onto a cold load, i.e. one that

has not been powered for a prolonged period, this can

impose a higher than normal load-current demand on the

system which could exceed normal settings. These

conditions can exist for an extended period and must not be

interpreted as a fault. To allow optimum setting levels to be

applied for normal operation, the cold load pickup feature

will apply alternative settings for a limited period. The fea-

ture resets when either the circuit-breaker has been closedfor a settable period, or if the current has been reduced

beneath a set level for a user set period.

27/59 Under/overvoltage

Each element has settings for pickup level, drop-off level and

Definite Time Lag (DTL) delays. It operates if voltage exceeds

setting for duration of delay. It can be applied in load shed-

ding schemes.

47 Negative phase-sequence overvoltage

Each element has settings for pickup level and Definite Time

Lag (DTL) delays. It operates if NPS voltage exceeds setting

for duration of delay.

59N Neutral overvoltage


11/36

67/67N Directional control

Phase-fault, earth-fault and sensitive earth-fault elements

can be directionalized. Each element can be user set to

forward, reverse, or non-directional. Directional phase-fault

elements are polarized from quadrature voltage. Earth-fault

elements can be user set to be polarized from residual

voltage or negative phase-sequence voltage.

81 Under/overfrequency

Each element has settings for pickup level, drop-off level and

Definite Time Lag (DTL) delays. It operates if frequency ex-

ceeds setting for duration of delay. It is typically applied in

load shedding schemes.

79 Auto-reclose

Each element provides independent phase-fault and earth-fault/sensitive earth-fault sequences of up to 5 trips, i.e.

4 reclose attempts before lockout. Auto-reclose sequence

can be user set to be initiated from internal protection

operation or via binary input from an external protection.

Each trip in the sequence can be user set to be either instan-

taneous (fast) or delayed. The user can set each reclose

(dead) time and the reclaim time.

Software

Reydisp Evolution

For communication with the relay via a PC (personal

computer) a user-friendly software package, Reydisp

Evolution, is available to allow transfer of relay settings,

waveform records, event records, fault data records,

instruments/meters and control functions. Reydisp Evolution

is compatible with IEC 60870-5-103.

Programmable logic

The user can map binary inputs and protection operated

outputs to function inhibits, logic inputs, LEDs and/or binary

outputs. The user can also enter up to 16 equations defining

scheme logic using standard functions e.g. timers and/or

gates, inverters and counters. Each protection element

output can be used for alarm & indication and/or tripping.

Ambient conditions

The recloser is designed for the normal operating conditions

defined in ANSI C37.60. This comprises an ambient tempera-

ture from 40 C to +55 C plus solar radiation.

Altitude correction factor

The dielectric strength of air insulation decreases withincreasing altitude due to low air density. The rated lightning

impulse withstand voltage values specified in the chapter

Technical Data apply to a site altitude of 1000 m above sea

level. For an altitude above 1000 m, the insulation level

must be corrected according to the opposite drawing.

The characteristic shown applies to the rated short-duration

power-frequency withstand voltage and the rated lightning

impulse withstand voltage.

To select the devices, the following applies:

U W U0 x Ka

U Ratedwithstand voltage understandardreference atmosphere

U0 Rated withstand voltage requestedfor theplace of installation

Ka Altitude correctionfactor according to the opposite diagram

Example

For a requested rated lightning impulse withstand voltage

of 75 kV at an altitude of 2500 m, an insulation level of90 kV under standard reference atmosphere is required as

a minimum:

90 kVW 75 kV x 1.2

Number of operating cycles

The recloser is designed for 10,000 operating cycles at

normal current.

According to the standard IEEE C37.60, the recloser has been

tested for 116 short-circuit breaking operations. The actual

number of short-circuit breaking operations is higher than

that, and can be even more than 200 depending on the pa-

rameters of the short-circuit current (amplitude, DC compo-

nent).
