REYROLLE

Features

• Consistent positive action

• Robust design for a long, reliable, service life

Description

Type AR relays are a range of electro-mechanical relays with up to 8

contacts and complying to BS142. They can be supplied in most

combinations of contact, flag and reset arrangements and with a fixed

time delay. Heavy duty contacts are available on most models.

The relays are identified by a series of numbers and letters which

define important relay features as follows:

Suffix letters are used to identify further features:

Suffix D - indicates a relay fitted with a suppression diode across

the coil to reduce the effects of the back emf which occurs on

switch-off.Suffix SB - identifies a relay with a series break contact to cut-offthe operating coil, thus the relay burden becomes zero afteroperation of this contact. Only available with AR relays which havehand reset contacts.

Type AR relay in a modular case.

Suffix T - identifies time delayed relays. Thereference is completed by adding a codenumber, see Operating Time.The following comments are provided as aguide to the various features of type AR relays.AR--1 and AR--2 Up to 8 self resetcontacts, 6 with a self reset flag, in anycombination of normally open or normallyclosed as required.AR--3 Electrical and hand reset contactssupplied with a contact reset mechanism inthe relay case cover.AR--4 Hand and self reset contacts, can besupplied with 2 hand reset contacts and amaximum of 4 self reset contacts. All thecontacts may be either normally open ornormally closed. AR--3 & 6 Reset coils are short time rated,we recommend that reset circuits include anormally open (cut-off) contact. Table 1.

Application The DDB20 time delay relay is particularly suitable for use in protection & control schemes where precision time delays are required. CB FAIL A typical use is for providing a definite time delay in circuit breaker failure protection. For example: The transformer multi-trip relays energize the DDB20 timer & if the circuit breaker (CB) fails to clear the fault within the pre-set (0.6s) the timer times out & operates a multi-trip relay. This in turn trips all CB’s on the section of the busbar connected to the CB, which has failed to trip. INDUCTION DISC RESET EMULATION Replacement of induction disc timing elements with solid-state relays can result in a loss of grading & reduced functionality due to the different reset characteristics. For example, the inherent slow reset time of induction disc relays provide an advantage in sensitive overcurrent schemes where pecking faults could go undetected due to the timer being instantaneously reset each time the current momentarily falls bellow the start setting. The DDB20 may be specified with a number of reset functions to avoid this problem & to suit specific protection applications.

Technical bulletin DDB20 Multi Range Digital Setting Time Delay Relay

DDB20 depicted in a 2M28 case.

Operation Made in Australia A crystal oscillator & embedded micro controller based timing circuit are employed to provide accurate timing & flexible functionality. When a control signal is applied to the timer initiate input, the down counter begins counting down from the thumb wheel switch setting. When the zero is detected, the output relay & flag changes state & the down counter stops. Three time ranges are selected via a front panel switch. A second function switch sets the timer to operate in time delay ON mode (Relay starts timing after the initiate control signal is applied & output contact picks up after the pre-set time delay has elapsed) or in time delay OFF mode (Relay output contact picks up instantaneously when the initiate control signal is applied, starts timing after the initiate control signal is removed & drops out after the pre-set time delay has elapsed). An LED on the front panel indicates when the relay has been initiated & flashes during timing. The DDB20 timer may be specified with a number of different reset functions to provide instantaneous reset, definite time reset or induction dist reset emulation. These functions are specified at time of order & are factory programmed. A switchmode power supply provides a very wide auxiliary operating range. A relay fail alarm is provided in the form of a C/O contact which is picked up when the auxiliary supply is healthy.

TIMING FUNCTION / INITIATE SIGNAL INPUT (Status input ) For accurate timing functions the DDB20 detects application or removal of a DC control signal. Two modes of operation are possible: Delay operate mode The relay is permanently connected to the auxiliary supply and is initiated by the application of a control signal. Application of the initiate signal (10ms minimum pulse length), starts the pre set timing cycle. During timing the front panel initiate LED will flash & then go on solid once the thumbwheel time setting has elapsed, this sets the output relay and visual indicator. The initiate LED is extinguished & the output contacts reset when the initiate signal is removed. The visual indicator may then be reset locally by the push button or remotely via the flag reset input. To achieve a simple but less accurate delay ON function, the initiate signal may be connected directly to the auxiliary supply. Timing will then commence when power is applied to the relay while removal of power will reset the time delay & output relay. This mode is only suitable for longer time delay settings as the switch mode power supply takes 100 – 500ms (Depending on Vx), to start which adds to the inherent time delay. Delay release mode The relay is permanently connected to the auxiliary supply. Application of the initiate control signal (10ms minimum pulse length), causes the output relay to set instantaneously (Rset). It will remain in this state until the control signal is removed, this starts the timing cycle & resets the output relay when the preset time delay is reached. The visual indicator is reset locally by the push button or remotely via the flag reset input. TIMING RESET OPTIONS Instantaneous If the initiate signal drops out before the preset time delay is reached the timing element will reset in 20 to 50 ms at 10X Is. Definite Time Reset (Treset) With this reset option a definite reset time must be specified. If the initiate signal drops out before the preset time delay is reached the delay timer will pause until the reset time has elapsed before resetting. If the initiate signal picks up again before the reset time has elapsed, the delay timer will restart the timing sequence from the paused timing point. Count Down Reset If the initiate signal drops out before the preset time delay is reached, the timer will count down toward reset. If initiate signal picks up again before reset is reached the timer will start counting back up towards the time delay pre set.

FAIL ALARM CONTACT 1 C/O contact (Picked up when auxiliary supply is healthy) OPERATION INDICATOR The standard relay has a hand & remote reset magnetic disc flag (permanent memory) indicator fitted to give visual indication that the output relay element has operated. Note that an auxiliary supply is required to reset the flag circuitry. TIME SETTING RANGES The DDB20 relays allow for precision time settings of between zero (Minimum operate time) & 99 seconds. This is achieved by the use of 2 decimal thumb wheel switches & a range multiplication switch on the front panel. Range Selector

WHEN SHOULD THE DELAY SET POINTS BE CHANGED? The time delay & function settings should only be changed when the timing initiate LED is extinguished. Changes made when the initiate signal is applied will only become effective once the initiate signal is removed. MINIMUM OPERATE TIME Time delay settings ≤ to the following minimum operate times will result in relay operate times equal to these minimums. Opto Type Status Inputs 25ms Relay Type Status Inputs 50ms TIMING ACCURACY (Setting & repeat accuracy) The timing accuracy is a combination of three factors: 1. Initiate time delay

Opto type status inputs: +1ms Relay type status input: +5ms

2. Relay timing error <1.25ms 3. Output relay delay +5ms The Idec relay type status input and relay outputs add electro mechanical delays of 20ms +5ms. The pre set time delay is compensated by the nominal 20ms delays introduced by these relays to improve accuracy. Maximum timing error is therefore: Opto type status inputs: < 7.25ms Relay type status input: <11.25ms

6RM QUAD Construction Each 6RM QUAD relay is comprised of the following elements:

1. Outer casing 2. Draw out module comprising four flag relays

The completed relay is shipped from the factory fully assembled but for flexibility, each part may be specified & numbered separately. The main components & features are depicted below in a size 4M case:


Case Mounting The following standard features are provided: RACK & FLUSH MOUNTING

DRAW OUT RELAY MODULE

REAR M4 SCREW TERMINALS

Case Construction The outer case is manufactured from zinc coated mild steel providing considerable strength & black powder coated surface finish for corrosion protection. Relay elements are mounted on fabricated fibreglass & Acetal components to provide reliable electrical isolation & simple cost effective construction.

Terminal Blocks High quality moulded terminal block(s) are utilized. The draw out function is made possible through the use of inner & outer terminal blocks, each with silver plated contact fingers to provide high current rating & very low electrical resistance. M4 screw terminals allow 2x crimp lug connections per point. Space efficient design allows 28 contact points per terminal block.

Reset Buttons Latching relays are provided with front mounted reset buttons.

Flag Indicators Each relay element is supplied with an operation (target) indicator. The indicator consists of a high visibility solid day glow orange mechanical flag which drops on energisation or de-energisation.

Case System Summary


Application The operating element for the 6RM QUAD Auxiliary Relays are based on our 6R MATRIX Series relays. The type 6RM Series elements are low burden auxiliary relays which can be used where a scheme demands several contacts for event recording, alarm initiation, contact logic arrangements, etc. The relay is supplied fitted with heavy duty contacts & magnetic blow-outs may be optionally specified for switching high DC inductive loads. Contacts are constructed from silver / copper alloy, shaped & positioned to ensure very reliable, low resistance operation. Over travel of the contacts during each operation causes a wiping action ensuring a clean “make”. Heavy duty contacts fitted with magnetic blow-out are recommended for breaking heavy or highly inductive DC loads. When these are fitted, the number of contacts available may be reduced.

Flag Indicators Each relay element is supplied with a flag (target) indicator. The indicator consists of a high visibility solid dayglow orange mechanical flag which drops on energisation or de-energisation.

Resets Resetting of flags & contacts may be either manual at the relay panel or electrical via a remote signal or both. The provision to separately reset the flag & contacts is also possible.

Electrical Reset Function COMBINED CONTACT / FLAG OPERATION & RESET 6RM210 With these types the flag & contacts operate & reset together. I.e. When the relay is operated the flag changes state & the contacts latch. Both the flag & contacts are reset if either the reset button is pressed or the electrical reset coil is energized. COMBINED CONTACT / FLAG OPERATION & INDEPENDENT RESET 6RM211 With these types the flag & contacts operate together but may be reset independently. I.e. When the relay is operated the flag changes state & the contacts latch. The contacts only are reset if the electrical reset coil is energized or the contact reset button is pressed. In both cases the flag is not reset. The flag can only be reset if the independent flag reset button is pressed.

EXAMPLE: 6RM206-A1 represents an auxiliary relay with a maximum of 4 heavy duty M or B (Magnetic blowouts fitted), hand reset contacts.

Four of these elements may be fitted in the 6RM QUAD relay.

Rear Terminal Count Depending on the number of terminals required, the 6RM QUAD can be supplied in either a 4M28 case with 28 screw terminals or a 4M56 case with 56 screw terminals. Considerable cost can be saved if the number of terminals can be limited to 28 or less. This can be achieved by limiting the number of output contacts & by wiring the operate coils with a common negative connection (Presuming they are operated from the same DC supply). Example 1: 6RM202 with 2M contacts per element & common negative on the operate coils equates to a requirement for 21 terminals. (2M x 2 + 1 operate) x 4 elements + 1 common = 21 A 4M28 case may be used. Example 2: 6RM202 with 6M contacts separate coil connections per element equates to a requirement for 56 terminals. (6M x 2 + 2 operate) x 4 elements = 56 A 4M56 case is required.


NUMBER OF OUTPUT RELAY CONTACTS The number of contacts & configuration are specified in table 2. The number of enclosure terminals available is the limiting factor necessitating some contacts to be connected to a common circuit. BURDEN (Maximum) Operating burden is <2W at nominal voltage. THERMAL RATING All operate & reset circuits are designed to withstand continuous application of 120% of nominal voltage INSULATION WITHSTAND In accordance with IEC 255-5: 2KV RMS between input & frame, output & frame, output & input. 1.2/50 5KV impulse between each terminal & earth, between circuits not normally connected together & between terminals of the same circuit. 6R RELAY CONTACT RATINGS

Supply supervision relays type XR152 & XR153


REYROLLE

Application

Types XR152 and XR153 relays are designed

to comply with CEGB and other

specifications for protection supervision

requirements and the monitoring of d.c.

voltage supplies. These applications require

relays with low operating current, visual

indication and the ability to initiate a remote

alarm. Both these relays have mechanical flag

indicators which show on de-energisation,

self reset on the XR152 and hand reset on the

XR153.

XR153 relay in a modular size 2 case

Features

• Low operating current

• High contact ratings


Description

Type XR relays are developments for specific applications of the

type AR relay range. They are electro-mechanical relays with a long

service life and complying with the appropriate requirements of IEC

255 and BS 142. These relays have a low operating current,

specific settings and time delayed drop-off. This latter feature is to

keep the relay in the operated condition during temporary

reductions in the battery voltage, such as those which occur just

prior to a fuse blowing or during a busbar fault when many trip

relays operate simultaneously. Healthy circuits therefore do not give

spurious alarms and the relay effected by the fuse failure provides

the alarm and indication necessary for accurate maintenance

attention.

Trip circuit supervision relays - types XR250 to XR351


REYROLLE

Application

Supervision of the trip circuit of a circuit breaker is desirable as a

means of ensuring the integrity of the trip circuit.

There are differing requirements for monitoring a trip circuit,

supervision of the trip circuit with the circuit breaker closed,

supervision with the circuit breaker open and closed and pre-

closing supervision. These XR relays are designed to meet all of

these requirements and in particular the requirements of BEBS S15

schemes H4 and H7.

Model range

XR151 and XR152

Trip supply supervision (see separate factsheet)

XR250 and XR251

Circuit breaker closed supervision. Will initiate an alarm and provide

indication with the circuit breaker closed for: Failure of the trip

supply, open circuit trip coil, an open circuit in the trip circuit wiring

and if the trip coil should fail to respond to a trip command.

XR350 and XR351

Continuous supervision with the circuit breaker in the open and

closed positions and in compliance with the scheme requirements

of BEBS S15 scheme H7. XR350 & 351 relays also have a contact

for pre-closing supervision, where a circuit breaker is prevented

from being closed if trip relays have not been reset.

BEBS S15 scheme H7 is applicable to trip circuit voltages of

125Vd.c. and 240Vd.c.

Description

Type XR relays are developments for specific applications of the

type AR relay range. They are electro-mechanical relays with a

consistent positive action, a long service life and complying with

the appropriate requirements of IEC 255 and BS142. Models

XR250/251 have two attracted armature elements, XR350/351

have three. These relays incorporate a time delay on de-

energisation to keep the relay in an operated condition during

temporary reductions in the battery voltage.

Ferro-resonance alarm relay-type XR309


VA TECH ELIN GROUP

REYROLLE

APPLICATION

On supergrid systems the phenomenon of ferro-

resonance may be experienced following

de-energisation of a directly connected transformer, and

the ferro-resonance may be sustained by the induction

from an energised parallel circuit. Re-energising the

transformer whilst in a ferro-resonant state can risk

severe switching overvoltages, therefore where there is

such a risk, a ferro-resonance alarm relay is essential.

OPERATION

The relay will detect ferro-resonance, with the system

energised or de-energised, as follows:

• On system de-energisation, the secondary voltage

falls below the reset level, and all 3 elements drop-

off. In the event of ferro-resonance occurring two out

of three elements will remain energised.

• If ferro-resonance is induced onto a de-energised

system the relay will only respond if the amplitude

of ferro-resonance is above the relay element

pick-up level 40V a.c.

• Relay contacts are wired to initiate a type DDB

timer, which in turn will initiate the alarm.

DESCRIPTION

This relay provides a ferro-resonance alarm as required

by NGTS 3.15.2 scheme F1. Under normal healthy

conditions, with the system energised or de-energised,

all the relay elements will be in unison and either

operated or un-operated.

The three attracted armature relays are connected

phase-to-phase via full wave rectifiers.

Application The 2V68 is a three phase monitoring device designed to provide continuous supervision of the buswires in high impedance type buswire protection schemes. The relay will detect open circuited buswires as well as open circuited main current transformers. The relay provides three (3) latching N/O alarm output contacts to signal faults. Three (3) additional N/O latching output contacts are provided for an integral buswire CT shorting facility.

Technical bulletin 2V68 Busbar CT Supervision & Shorting Relay

2V68 depicted in a 4M28 case

Operation Made in Australia The 2V68 type relays have a setting range of 2-14V adjusted on a per phase basis from calibrated potentiometers at the front panel. The relay is continuously rated at 300V RMS & no external components are required. Isolation from the main CT’s is achieved by using a transformer whose primary winding is connected in series with a high value and power rated resistor. The secondary output signal from this isolating transformer is fed into a current to voltage converter, then rectified for comparison with the front panel pre-set value. The AC input is continuously monitored & when it exceeds the pre-set level. Latching contacts are actuated after a three (3) second time delay. Three (3) latching contacts are intended to be connected across the buswires of the busbar protection thus short-circuiting the busbar protection relay & rendering the protection of the zone concerned inoperative. The remaining three (3) latching contacts are available for alarm & signaling functions. Operation of the relay is indicated by a hand reset flag. A switchmode power supply provides a very wide auxiliary operating range. A relay fail alarm is provided in the form of a C/O contact which is picked up when the auxiliary supply is healthy.

Restricted earth fault relay - type 5B3


REYROLLE

Features

• Low settings can be achieved

• Stability based upon plant capacity

Application

The 5B3 relay is ideal for restricted earth fault protection of

transformer windings or phase and earth fault protection of

reactors and the stator windings of large machines. This relay may

also be used for high impedance busbar protection.

High impedance schemes have the advantages over low

impedance schemes that a more sensitive setting can be obtained

without any loss of stability and the primary fault setting calculation

is simpler. Current operated schemes are more susceptible to

maloperations from through faults unless greater care is taken with

the selection of the current transformers.

For some restricted earth fault applications the primary fault setting

needs to be greater at harmonic frequencies than the setting at the

fundamental frequency. The 5B3 relay uses a low pass filter circuit

to achieve this. No adverse reduction in fault setting can occur with

the high frequency currents which may be produced during

switching.

Description

The relay uses a type B61 attracted armature element energised

via a low pass filter circuit and a full wave rectifier. The relay has a

pre-set setting of I5V. Other resistors are introduced into the circuit

to provide the voltage setting range up to 270V in increments of 5V

using heavy duty DIL switches.

Included within the relays are the essential non-linear resistors to

limit the peak voltage output from saturated C.T.s, these resistors

protect the CT. insulation and secondary wiring.

Current transformer requirements

Experience has shown that most protective C.T.s are suitable for

use with the high impedance relays and that where the CT.s are

specifically designed for this protection their overall size may be

smaller than that required for an alternative current balance

protection. The basic requirements are:

a) All C.T.s should, if possible, have identical turns ratios.

b) The knee point voltage of each CT. should be at least 2x Vs.

The knee point voltage is expressed as the voltage applied to the

secondary circuit with the primary open circuit which when

increased by 10% causes the magnetising current to increase by

50%.

c) C.T.s should be of the low leakage reactance type. Most modem

Type 5B3 relay

CT.s are of this type and there is no difficulty in

meeting this requirement. A low leakage

reactance C.T. has a jointless ring type core,

the secondary winding evenly distributed

along the whole length of the magnetic circuit

and the primary conductor passes through

the approximate centre of the core.

Stability

For stability the voltage setting of the relay

must be made equal to or exceed the highest

value of V calculated below:

V=I (Rct+RI)

Where:

RI = The largest value of pilot-loop

resistance between the CT.s and

the relay

Rct = The secondary winding resistance of

the CT

I = The C.T. secondary current

corresponding to the maximum

steady state through fault current of

the protected equipment

Fault setting

It should, however, be noted that because the

operating voltage of the relay circuit is

relatively high, the excitation currents of the

C.T.'s in parallel with the relay may comprise

a large proportion of the fault setting

Primary fault setting = N( I0 + I I + I2 + I3)

Where:

I0 = Relay operating current

I I etc = Excitation current of each CT. at the

relay setting voltage

N = C.T. turns ratio

Circuit breaker fail & current check relay - type 2DAB

Features

• Low burden• 3 pole, Phase segregated inputs• High speed pick-up and drop-off• Low overshoot• Modular design• Wide range of settings• Instantaneous or time delayed

DescriptionType 2DAB relay meets the requirements for currentcheck relaying in a circuit breaker fail scheme or maybe used to monitor current flow prior to sequenceswitching; e.g. mesh corner schemes. The 2DABcurrent check relay detects the circuit breaker failure totrip and to ensure discrimination has a fast reset timeand a minimum overshoot time.

Each pole of the relay is phase segregated andoperates independently via its level detector andinterface area. The provision of the interface areaallows for the factory fitting of output relays to thecustomer's requirements. With this flexibility theinterface area relays can be manufactured with up to 9change- over contacts, connected as phase segregatedgroups of three, or as three phase outputs. Thestandard arrangement is with 4 normally open outputcontacts.

Each level detector initiates a time delay, set by theuser, which delays operation of the output relay. Thiscan be set to zero for instantaneous operation.

Type B3 High Impedance Differential Relay

Type B3 3 pole relay in modular case

Application

High impedance busbar protection, circulating current protection and auto transformer protection.

Description

The type B3 relay is a rectifier fed type B element with sensitive current setting and low operating burdens. External resistors are used to give the relay a voltage setting. A metrosil is fitted internally across the rectifier, however an external metrosil may also be required. Metrosils are non-linear resistors used to protect the relay components, the insulation of secondary wiring and current transformers, by suppressing high voltage peaks which may otherwise be developed by the virtually unloaded current transformer secondary winding under internal fault conditions.

Protection application

Where significant capacitance is included in the protected zone (e.g. in the case of restricted earth fault or a delta winding at the remote end of a feeder) sensitive settings may only be used in the conjunction with a high frequency filter. For such applications relay types 4B3, 5B3 or DAE should be used. Significant capacitance isdefined by comparison of the primary current setting with three times the in-zone capacitance current or nine times the in-zone capacitance current, per phase, for solid or resistance earthed systems respectively.

Current transformer requirements

Experience has shown that most protective current transformers are suitable for use with this protection. The overall size may in fact be smaller than that required for an alternative current balance protection using say a biased relay.

The basic requirements are:

1. All the current transformers should have identical turns ratios.

2. The knee point voltage of the current transformers should be at least twice the relay setting voltage. The knee point voltage isexpressed as the voltage applied to the secondary circuit of a current transformer which when increased by 10% causes the magnetising current to increase by 50%.

3. The current transformers should be of the low leakage reactance type. Generally most modern current transformers are of this type and there should be no difficulty in meeting this requirement. Low leakage reactance current transformers have a jointless core with the secondary winding evenly distributed along the whole length of the magnetic circuit, and the primary conductor passes through the centre of the core.

Class "X" current transformers to BS 3938 can be specified to meetthe above requirements and are recommended.

A.C. undervoltage relay - type B6


REYROLLE

Application

An undervoltage relay with a repeat relay having changeover

contacts for voltage changeover or voltage selection.

Description

Type B6 relays can be supplied with a combination of a.c. voltage

measuring and d.c. elements to meet various voltage switching

requirements.

1. 1a.c. & 1d.c. Single phase arrangement

2. 2a.c. & 1d.c. Three phase arrangement

3. 2a.c. & 2d.c. Vedette case only, 8 contacts

Under healthy system conditions the a.c. element, or elements, are

energised and their respective contacts are held closed. The

closed contacts complete the circuit to the rectifier thus keeping

the rectifier fed d.c. element energised. Two contacts wired in

parallel are used on the a.c. elements for security. If an

undervoltage condition occurs the a.c. elements are de-energised,

these in turn de-energise the d.c. repeat element, switching over

the external circuits via the changeover contacts. When the supply

voltage is restored, and rises above the pick-up value of the a.c.

elements, the relay will reset and return the external circuits to their

original connection.

Relay case terminals and typical connections are shown in Fig. 2.

With the fuses intact and the voltage magnitude at an acceptable

level the relay will be energised, an interruption of the supply, e.g.

by the blowing of a fuse(s), will de-energise one or both of the a.c.

measuring elements thus de-energising the d.c. element and

switching the supplies over. Failure of phase “B” will effectively

connect the two a.c. elements in series, the resultant reduction in

voltage being sufficient to cause de-energisation.

If the 3 phase supply is derived from the secondary windings of a

voltage transformer and warning of primary circuit fuse failure is

required, then a type B37 relay can be supplied for connection

across an open delta tertiary winding of the voltage transformer.

Surgeproof intertrip relays - type BD


REYROLLE

Application

For the tripping of remote circuit breakers in an inter-connected

power system where the fault current may be fed from more than

one source.

Following fault detection and operation of the local circuit breaker,

a d.c. trip signal is transmitted via pilot cables to the BD intertrip

receive relay. These trip the remote circuit breaker in order to

completely isolate the fault.

Very high voltages may be induced in the pilots, especially during

heavy fault conditions, and the relay must remain inoperative to all

but the correct trip signal. The BD relay caters for transverse

voltages up to 5kV rms and longitudinal voltages of up to 5kV or

15kV. Its operating time is unaffected by induced voltages which

may be present at the time of applying the intertrip signal. Any type

of pilot cable can be used, but the maximum loop resistance

should not exceed 1,000 ohms.

Description

There are two component units, the relay and the filter unit.

The filter unit contains inductors, capacitors, and setting resistors

encapsulated in a thermo-setting resin. The relay comprises a

moving coil element insulated for either 5kV or 15kV, and an

attracted armature repeat relay with a hand reset flag. Limiting

devices are connected across the moving coil to by-pass the initial

and final peak switching surges.

Multi-ended intertripping schemes

Multi-ended intertripping schemes often occur in practice and type

BD surge proof relays are suitable for such applications. In order

to achieve optimum performance they should be operated as near

as is reasonably possible to their design parameters. To obtain this

two main requirements should be fulfilled.

A.C. Requirements These surge proof relays have been

designed to remain stable with induced voltages of up to 5kV in

pilot wires having a loop resistance not exceeding approximately

1,000ohms. It is therefore recommended that the loop resistance

of the pilots between any two feeder ends, between which induced

pilot voltages are expected, should be maintained within the range

of 500 to 1,000ohms. When determining the loop resistance the

pilots at the remote end are assumed to be short circuited. If the

loop resistance obtained is less than 500ohms, the resistor in the

filter unit, at the end being considered, may be used to make the

effective loop resistance greater than 500ohms.

D.C. Requirements In order to ensure

satisfactory operation of the BD relays at all

receiving ends, the d.c. currents in each

receiving end relay should preferably be equal

to or in excess of 12mA. The d.c. resistance

of the type BD relays, as seen from the pilots

across terminals (P3, R2) is about

3,000ohms. Using this value the minimum

d.c. intertrip voltage required at the sending

ends can be estimated.

High impedance circulating current relay - type DAD


REYROLLE

Description

The type DAD relay provides high-speed, high impedance, current

differential protection with individual open-circuit monitoring of the

CT secondary circuits. An advanced design input filter with a

harmonic rejection circuit improves overall protection stability by

rejecting the harmonics generated by the onset of CT saturation.

The relay is provided with four output relays each with two

contacts. Three of the relays, those normally associated with the

alarm function, can be selected for latched/non-latched contact

operation.

Application

High impedance busbar zone protection and circulating current

protection of auto transformers, motors and generators.

Transient stability under through fault conditions is a problem with

many forms of differential protection due to variations in CT

magnetising characteristics. As saturation is approached, the CT

output current waveforms become increasingly distorted with a

high percentage of 3rd and other higher odd harmonics. These

problems can be overcome by either using biased differential

protection, or more elegantly by the use of high impedance

schemes. In the latter case the relay settings are calculated

assuming one CT is completely saturated. Using this worst case

condition the voltage and current settings for type DAD high

impedance protection can be precisely calculated with known

stability margins. Intermediate conditions, where a CT is only

partially saturated, increases the stability margin. This approach

enables schemes to be engineered using CTs with relatively low

knee-point voltages.

The DAD relay also incorporates supervision of the CT secondary

circuits. This supervision is traditionally provided by a sensitive

alarm relay, but this integration of protection, CT supervision and

associated timers in the DAD considerably simplifies system

design and secondary wiring. Zone switchout relays are

recommended to switch out an affected zone.

Type DAD relay in a modular size 6 case

Features

• High speed of operation

• Input filter characteristic rejects d.c. offset transients and

provides excellent harmonic rejection

• Integrated open circuit current transformer supervision alarm

• Low a.c. and d.c. burdens

High impedance busbar protection is

recommended for all switchgear applications

where faults must be cleared in the shortest

possible time. High impedance schemes can

provide lower fault settings and a better

through-fault stability than possible with most

other schemes.

The stability of a current balance scheme

using a high impedance relay circuit depends

upon the relay voltage setting being greater

than the maximum voltage which can appear

across the relay under a given through fault

condition. Stabilising resistors and metrosils

complete the scheme.

Current transformers

Experience has shown that only Class “X”

CTs to BS3938 meet all the basic

requirements for this type of protection. For

most applications it will be found that the

overall size of the CT will be smaller than that

required for alternative current balance

protections.

GF - surgeproof intertrip receive relays

APPLICATION

Under fault conditions an interconnected power system may feed fault-current from more than one source, and in order to isolate the fault it becomes necessary to initiate the tripping of remote circuit breakers.

The above requirement is particularly important when protecting Feeder-Transformers connected to the system without circuit breakers. In the event of a transformer fault, tripping of the local low voltage circuit breaker will not remove the fault from the system and it becomes essential to trip the remote high voltage circuit breaker. Intertripping can use various information linkshowever type GF relays are for use with pilot wires.

Complete reliability of the intertrip signal in the presence of interference is of the utmost importance particularly during internal fault conditions when this interference may be severe. Simple systems using d.c. relays may be adequate for pilot wire lengths of up to 2km, however it should be noted that receive relays must not be unduly sensitive to the capacitive energy stored in the pilot wires. A d.c. relay system may also be used for longer lengths of pilot wire provided that precautions are taken to avoid spurious operation due to either induced voltage or to differences in earth potential at the send and receive ends.

The effects of induced voltage are most significant under earth fault conditions when both transverse and longitudinal voltages appear across the conductors of the pilot cable when fault current returns through the earth path and the earth wire. The degree ofinduction depends upon earth resistivity, the disposition of auxiliary conductors relative to primary conductors, the presence of the earth wire and the screening effects present in both primary and auxiliary conductors.

DESCRIPTION

Type GIF relays are designed to meet the demand for a simple surge-proof intertrip receive relay.

Type BID surge-proof receive relays operate in conjunction with a separately mounted filter unit which only responds to d.c. remaining stable with induced a.c. voltages of up to 5kV across its terminals. However experience has shown that although longitudinal voltages can be of the order of 5kV, transverse voltages across the pilot cores are of much lower magnitude. It follows that although it is necessary to have a high insulation level to earth, it may not be necessary to have the full 5kV surge-proof capability.

GF relays comprise an attached armature element delayed on pick-up and with non-linear shunt resistor and a series resistor. They are surge proof up to 500V rms 50Hz (steady state or switched).

GF relays are rated for 60V d.c., when required to operate at higher supply voltages an external dropper resistor is supplied,

High speed feeder protection - type Solkor-R/Rf


REYROLLE

Features

• High transient stability.

• High speed operation.

• Low phase and earth fault settings.

• Bleed-off up to 20%.

• Options of 15kV pilot isolation and pilot

supervision

Application

Solkor-R/Rf is a development of the well proven Solkor-R

protection which offers improved performance and is suitable for

an increased range of pilot wire conditions. It can be selected to

operate in either R or Rf mode using internal links.

Experience has shown that the majority of medium voltage feeders

can be satisfactorily protected by equipment with a pilot to earth

insulation level of 5kV. Situations where, due to induction or a rise

in substation earth potential, pilot insulation of between 5kV and

15kV is required, this can be met by the Rf mode using a 15kV

isolating transformer with the relay at each feeder-end.

Solkor-R/Rf relay in a modular size 6 case

Description

Solkor-R/Rf is designed to operate over pilot

circuits of a standard resistance. This

standard operating value is obtained by

adding a padding resistance at each feeder-

end relay. This ensures that the protection is

always operating under constant conditions

of pilot resistance and its performance is

therefore independent of this.

At each end of the feeder the secondary

circuits of 3 current transformers are

connected to a summation transformer which

provides a single phase quantity for use over

the pilot wires. Stability is achieved by current

balance using the Solkor operating principle

of establishing the electrical centre of the pilot

circuit within the relay which has positive

polarity. Under healthy conditions, the

measuring elements remain in the negative

part of the circuit and are thus biased against

operation.

Solkor-R/Rf provides two-ended tripping for

in-zone faults. Where it is necessary to

intertrip the remote circuit breaker to clear

faults external to the Solkor protective zone,

three schemes are available utilising the

Solkor relays and pilot wires.

High speed feeder protection - type Solkor-R/Rf

It is not recommended that any other burdens

should be included in the current transformer

circuit: Also the secondary magnetising

currents of current transformers at opposite

ends of the feeder should not differ by more

than amperes for output voltages up to

volts.

To ensure good balance of the protection the

current transformers at the two ends should

have equal ratios. Close balance of ratio is

provided by Class "X" current transformers to

BS 3938, where ratio error is limited to ± 0.25

%, and are recommended.

Settings

Primary fault settings with average current

transformers and zero pilot capacitance are

given in Table 1. Values are expressed as

percentages of the current transformer rating.

Normally the summation transformer "N" tap is

used. While greater sensitivity can be obtained

using the "N1" tapping, care is necessary as

when current transformers with relatively high

excitation currents are used the "N1" tap may

give little or no advantage.

Pilots

Any type of pilot having a grade of insulation

which can withstand 500 volts between the

cores may be used. The pilot circuit should be

capable of withstanding the voltage imposed

by the power system.

Solkor pilot supervision equipment


REYROLLE

Features

• Continuous supervision of the pilot link.

• Open circuits and short circuits of pilot wires alarmed.

• Crossed pilot wires detected.

Application

This equipment will provide pilot supervision for Solkor-R 5 kV and

Solkor-Rf 5kV and 15kV schemes.

Description

Scheme simplicity is achieved by careful design so that switching-

out of the pilot supervision equipment is not necessary. Starting

relays are thus avoided and double-end tripping is obtained

without infeed being required at the remote end except where

guard relays are included in the scheme.

The pilot wire information link is vital for the stability of pilot wire

feeder protections. Supervision is by the injection of a d.c supply at

one (send) end, with a continuously energised, polarised, relay

monitoring this supply at the other (receive) end. Thus an open or

short circuit, or crossing of the pilot wires will cause the receive

relay to be de-energised. The sensitivity and insulation

requirements limit the contacts the receive relay can provide, so a

repeat relay is used to provide flag indication, contacts for alarm

initiation and a delay of approximately 400ms on drop-off to

prevent spurious pilot fail alarms during fault conditions.

Equipment for 5kV insulated pilots can be supplied in modular or

Vedette cases, 15kV components are only available in Vedette

cases.

Optional supervision supply fail relay

Used to provide suitable alarms for failure of the supervision a.c

supply. Suitable relays are type AR121 or type B22.

Optional guard relays

Guard relays can be applied to prevent the protection tripping at

below fault levels. Guard relays need to be applied if tripping of the

Solkor protection is to be prevented when pilots become open

circuit and the normal load current is, or becomes, above 66% of

the Solkor three-phase setting, e.g. where there is a large amount

of construction work adjacent to the pilot wire route. A suitable

relay is the type B69.

Guard relays will not affect the speed of operation of the protection

because they only act to check the tripping contacts of the Solkor

relay and have no effect on the protection measuring circuits.

Guard relays may also be arranged to hold the repeat relay

5kV Solkor supervision receive relay in modular case

energised during fault conditions and thus

prevent a pilot failure alarm for extended

through-fault current clearance times.

Where 15kV insulated pilots are used some

utilities prefer the pilot wiring not to be in the

relay panels because of the possibility of high

voltages being induced onto them under

heavy through-fault conditions. In these

instances the Transformer-rectifier unit and

the receive relay can be mounted in the pilot

termination cubicle; the supply fail and repeat

relays may be panel mounted.

Solkor intertripping


REYROLLE

Features

• Multiple use of pilot link

• Simple to use

• Injection schemes for decisive intertripping

Application

Solkor provides double ended tripping for in-zone faults. Use can

also be made of the Solkor pilot link, and the remote Solkor relay,

to intertrip the remote circuit breaker to clear faults external to the

Solkor protective zone, for example to backtrip from a busbar or

transformer protection. There are several possible methods

available, the choice between them being dependant upon the

current available through the protected feeder for the fault

conditions which require intertripping.

Description

1. Open Circuiting of Pilots - Solkor-R and Solkor-Rf

Since Solkor protection is a current balance scheme, fault current

intertripping can be effected by open circuiting the pilot loop. The

magnitude of the current required through the remote current

transformers to cause operation of the relay depends somewhat

on the intercore capacitance of the pilot line. For reliable

intertripping the minimum fault current through the remote current

transformers should not be less than twice the nominal fault setting

for each type of fault.

2. DC Injection Intertripping

Solkor R may also be intertripped by the direct application of a

110V dc voltage source to the local end of the pilots. This dc may

be derived from a 5kV or 15kV isolated intertripping battery or from

a secure full wave rectified 110V, 50/60Hz, voltage derived from a

5kV or 15kV isolation transformer.

3. Injection Intertripping - Solkor-R & Solkor-Rf

Injection intertripping is used where decisive intertripping is

required, irrespective of the current in the protected feeder, and to

avoid possible interaction between the injected signal and power

frequency voltages. Its use also avoids the requirement for 5 kV or

15 kV insulated intertripping batteries.

Injection intertripping is not suitable for use with guard relays (which

place normally open contacts in series with the Solkor relay

contact) or for Solkor-R with Supervison applied to the same pilots,

(for such schemes Supervision may be carried out over spare

cores). Because a different inverter is required, Solkor-Rf can use

both injection intertripping and supervision over the same pilots.

Inverter Unit

The send equipment comprises an inverter

and a type TEC relay to switch the a.c.

intertripping signal, Solkor-Rf requires an

additional time delay relay. The receive relay is

the remote Solkor relay. It is unnecessary to

continuously energise the inverter, normally a

full power signal is sent for 2 secs. followed by

either de-energisation of the inverter or by a

reduced inverter output which holds the

remote relay operated, see Fig, 1.

Note applicable to all schemes:-

Where contacts are directly connected to the

pilot wires then 5kV/15kV isolation must be

maintained from earth and other circuits. For

more details of schemes contact Reyrolle

SURGE-PROOF INTERTRIP SEND RELAY TYPE TEC

APPLICATION

lntertrip Send Relay for use where the pilots are prone to high induced voltages.

Under fault conditions an interconnected power system may feed fault current from several sources, and in order to isolatea fault it becomes necessary to initiate the tripping of one or more remote circuit breakers. Remote intertripping of circuit breakers requires a fast, multi-contact, intertrip relay capable of withstanding the high voltages which may be induced in the pilots.

DESCRIPTION

The type TEC relay comply with British Generating Board Engineering recommendation M16/2 class EB2. They consist of three elements:

(a) Type F relay. (b) Type B34 relay delayed on energisation. (c) Type TCD static timing relay.

MODEL RANGE

Four type TEC relays are available: 5kV insulated contacts for pulse or sustained intertrip. 15kV insulated contacts for pulse or sustained intertrip. 5kV insulated contacts for 2 stage intertrip. 15kV insulated contacts for 2 stage intertrip.

Pulse lntertripThe F relay is energised and within 10ms the intertrip contacts are closed. They are then maintained for a period of two seconds. When the initiating contact IC closes, the operating coils of the types F and B relays are both energised, their operating times are 10 and 100ms respectively. The type F relay contacts complete the intertrip circuits and the series contact F1 open circuits the operating coil to prevent battery drain. Contact F2 initiates the time delay relay for the reset operation. The type B34 relay contacts then 'pick-up' open-circuiting the type F relay operating coil, contact B1, to prevent a repeat operation upon reset. After the time delay elapses contact T1 is closed and the type F relay resets.

Sustained lntertrip

Within 10ms the intertrip circuits are closed, this condition being maintained for two seconds after the initiating contact opens. The operation of the circuit is similar to that describedin the pulse intertrip arrangement, with the exception that contact B2 is used to ensure that the time delay relay is not energised until the type B34 relay is de-energised, i.e. when the initiating contact IC is opened.

2 Stage lntertrip

Where the intertrip signal applied to the pilots is derived froma DC/AC inverter or DC/DC converter, such devices may be damaged if energised unloaded for long periods. Another small attracted armature element is incorporated in the TEC relay so that the inverter or converter is only energised for 2 seconds in the 'pulse intertrip' scheme, or for the duration of 'sustained intertrip'. For the latter the signal can be held at full level for 2 seconds then reduced to a 'hold on' level provided that the design of inverter or converter permits an economy resistor to be switched into the drive circuit to its output transformer.

1. SAFETY

The commissioning and maintenance of protection equipment should only be carried out by skilled personnel trained in protective relay operation and capable of observing all the necessary safety precautions and regulations appropriate to the equipment and also the associated primary plant.

Equipment should be isolated from auxiliary supplies and the circuit breaker trip circuit prior to commencing any work.

2. UNPACKING, HANDLING & STORAGE

On receipt unpack the equipment and inspect for any obvious damage. It is not normally necessary to remove it from its polythene bag unless some damage is suspected or if it is required for immediate use.

If damage has been sustained a claim should immediately be made against the carrier, also inform Reyrolle Protection and the nearest Reyrolle agent.

When not immediately required return the equipment to its carton and store in a clean, dry, place.

3. DESCRIPTION

The range of 2RMLG Test Blocks, housed within an Epsilon enclosure, offers facilities for monitoring and secondary injection testing of power system protection schemes in conjunction with the MMLB 01 multi-fingered test plug. The MMLB 02 is a single fingered test plug available for monitoring current flow in individual circuits connected through the test block.

The 2RMLG Test Block has 14 pairs of spring loaded contacts which are linked to a terminal block positioned at the rear of the enclosure.

The 2RMLG07 is coded to only accept the MM2B07 Test Plug which has connection terminals 21, 23, 25 & 27, internally For typical application see Fig 4.

The 2RMLG08 is coded to only accept the 2RMLB08 Test Plug which has internal pairs 1&3, 5&7, 9&11 and 15&17 shorted together internally For typical applications see Figs 5, 6, 7 & 8.

Each pair of contacts is normally closed completing the circuit through the test block when the associated protection equipment is in use.

For testing purposes the test block can be assessed by removing the front cover. The 2RMLG 01 has a metallic probe attached to the front cover assembly which when withdrawn open circuits the 2 contacts at position 13 and 14.

The main dc auxiliary supply to the protection scheme or relay can be wired to this circuit to prevent inadvertent tripping of the protection circuit after removal of the cover and during the test procedure.

The 2RMLG 02/07/08 do not include the above facility and contacts 13 and 14 are normally closed. These contacts must not be used for current circuits, as the relevant contact finger on the MMLB 01 test plug is shorter in this position.

The short test finger in position 13-14 on the MMLB 01 will open contacts 13-14 in the test block after the other fingers have made contact in all other positions.

When the cover is removed a yellow fascia is revealed which is attached to the test block this gives a visual indication and warning that the protection scheme or relay is not in service.

The insertion of the MMLB 01 test plug into the 2RMLG assembly (as shown in figs. 1 and 2) open circuits the contact pairs. The MMLB 01 has 28 test points each position being identified by a number which corresponds with the terminations on the 2RMLG.

It is recommended that the protection scheme or relay is wired to the even numbers of the test module. To ensure the scheme wiring is routed logically it is recommended that the 2RMLG is always positioned on the right-hand side of the relay, when viewed from the front. The connections to other equipment such as CTs, VTs, and dc supplies should be made to the odd numbered terminals indicated on the 2RMLG. This will ensure that on connection of the MMLB, the sockets on the even numbered side of the test plug are the isolated relay circuits and the sockets on the odd numbered side are connected to the potentially live supplies as shown in Figure 3 & 4.



2RMLG Operating Recommendations

Note: It is important that the sockets in the test plug (MMLB01&02) which correspond to the current transformer secondary windings are linked prior to the test plug being inserted into the test block.

This will ensure that the current transformer secondary windings are short circuited prior to disconnection from the protection scheme or relay (as shown in Figure 3).

If the The dc auxiliary supply is to be used during testing it can be linked using the sockets in the test plug.

Operation of the contacts can be monitored by connecting the test equipment to the protection scheme or relay with the even numbered sockets of the test plug.

If a number of 2RMLG test blocks are connected to a relay it is recommended that the dc supply be routed through each of them to safeguard against inadvertent operation.

Single-finger Test Plug

The Single Finger Test Plug consists of two contact blades each insulated from the other and each connected to a lead, as shown in Figure 1.

This test finger is used to insert into individual test positions as shown in Figure 1 and is an alternative to the multi-fingered test plug. It is used to monitor the current in any of the circuits passing through the test module.

Note: An ammeter set at the correct range should be connected to the leads prior to the plug being inserted, especially if a CT secondary circuit is being monitored.

Mechanical Specification

The 2RMLG is a size E2 unit in the Epsilon range of enclosures.

The overall dimensions and panel fixing details are shown in Figure 9.

The rear terminal block has 28 terminals each with an M4 screw outlet for the attachment of external wiring, fitted with L shaped pre-insulated ring tongue terminations.

MLB series Multi-fingered test plugs

The MLB series are inserted into the 2RMLG test socket and is securely retained by means of two knurled screws. The MMLB01 & 02 test plugs incorporate 28 test sockets, each socket accepting a 4mm diameter plug.

MLB series Accessories

The following are supplied with the MMLB01 test plug:

1. 4 short plug links. Each comprised of 50mm of interconnecting cable with a 4mm plug each end.

2. 4 long plug links. Each comprised of 150mm of interconnecting cable with a 4mm plug at each end.

3. 6 spare 4mm plugs. These accept up to 2.5sq. mm flexible insulated cable for test lead purposes.

MMLB02 Single-fingered test plug

The MMLB02 is supplied pre-wired with a length of 1sq. mm twin core flexible insulated cable. For polarity identification one core is black and the other is red.

MMLB 07 CT Shorting

The MMLB 07 is the same unit as the MMLB 01 with the addition of an integral ct shorting contact between terminals 21, 23, 25 & 27 and is coded to be used with the 2RMLG07 Test Socket only.

2RMLB 08 with Shorting Contacts

The MMLB08 is identical to the MMLB01 with shorted contact pairs 1&3, 5&7, 9&11, 15&17 and is coded to be used with the 2RMLG08 Test Socket only.

4. PRECAUTIONS

BEFORE inserting a Test Plug into a Test Socket carrying current transformer secondary circuits.

ENSURE that the Test Plugs corresponding to the current transformer circuits are short-circuited.

This is to ensure the current transformer secondary circuits are not inadvertently open-circuited during insertion of the last plug.

BEFORE inserting a Test Plug to measure current.

ENSURE that the ammeter is on the correct range and that it is connected to its test leads.

5. CONNECTIONS

The connections will depend upon the scheme and details must be obtained from the appropriate diagrams. If it is necessary to use the d.c. auxiliary supply during testing, then a test link may be fitted across the sockets in the Test Plug.
