Application
Operating records for overhead power
lines reveal that most faults are of a
transient nature (e.g. lightning induced) &
that service interruptions may be
minimized by use of automatic reclosing of
circuit breakers.
An automatic reclosure of the circuit
breaker, after the fault clears, provides
improved service continuity & system
stability.
The 1B230 Series Reclose Relay provides
for single or double shot automatic
reclosing of circuit breakers, following
interruption of supply due to a fault in the
system.
Technical Bulletin 1B230
Single or Double Shot Auto Reclose Relay
1B230 depicted in a 4M28 case
Operation Made in Australia
The 1B230 auto reclose relay provides up to two shot auto reclose control for distribution
and transmission systems. Dead times for both shots (reclose attempts) are independently
adjustable.
An auto reclose cycle is initiated by operation of a protective relay (INP Main Protn),
provided the circuit breaker is closed until the instant of protection operation.
Dead time 1or 2 start when the circuit breaker has tripped (INP CB Aux Switch) and the
protection has reset.
At the end of the dead time, a CB close signal is given (output RLY CB Close Sig),
provided input signals are present indicating that system conditions are suitable (INP Safe
To Close), and the circuit breaker closing spring, or other energy source, is fully charged
(INP Spring Charge).
The safe to close signal is taken from a contact on a separate voltage monitor or
synchronism check relay, and the spring charged signal is taken from an auxiliary switch
contact on the circuit breaker. The CB close signal is cut off when the circuit breaker
closes.
Once the output pulse to close the circuit breaker is completed, the reclaim time starts. If
the circuit breaker remains closed until the reclaim timer times out, the 1B230 resets if in
auto mode or goes to lockout.
However if the protection operates again & the circuit breaker trips before the reclaim time
has elapsed, the 1B230 either advances to the next shot in the programmed auto reclose
cycle, of, if all programmed reclose attempts have been made, goes to lockout.

BLOCK INSTANTANEOUS TRIPS OUTPUT
A Block Instantaneous Trips output (RLY Block Inst Pr) can be
arranged to block the trip function of non-discriminating
protection, such as low set instantaneous overcurrent or earth
fault protection, or distance protection operating with Zone 1
extension. This function is used to ensure that the final trip to
lock out for a persistent fault is made by discriminating protection
& can be set at the front panel to operate after the first trip, after
the second trip or to OFF (Function disabled).
The output relay is normally reset and to operates (contact
closes) to block non-discriminating protection.
This is suitable for most modern protective relays such as
Ohmega & Argus.
CIRCUIT BREAKER AUXILIARY CONTACT
An auxiliary contact on the circuit breaker (Closed when the CB is
tripped) is required to monitor the operation of the CB using the
INP CB Aux Switch.
LINE VOLTAGE INTERLOCK INPUT
Line status information is derived from input INP Line Volt Mon.
This feature inserts additional checks in the auto reclose initiation
and dead time start logic, such that an auto reclose cycle can only
be initiated if the line was live until immediately before the
protective relay operation, and the dead time cannot start until the
line has gone dead.
Front panel switch selection of Live Line IN or OUT.
CB RECLOSE SPRING STATUS INPUT
Application of a control voltage to the INP Spring Charge input
will defer the CB reclose output pulse (RLY CB Close Sig) until
the signal is removed. This function is used to ensure that the CB
will not receive a reclose pulse until after the reclose spring is
fully charged.
The spring charged signal is taken from an auxiliary switch
contact on the circuit breaker.
If the INP Spring Charge input defers the CB reclose output
pulse for 60s the 1B230 will go to lockout.
MAIN PROTECTION INTERFACE
Two input types are provided to interface with the main protection
to initiate the reclose cycle:
1. Shunt initiate Voltage input to INP Main Protn Shunt
Pulse Length >40 m Sec
2. Series initiate Current input to INP Main Protn Series
(optional) Current >1.2 Amp DC
Pulse Length >40 m Sec
Resistance <0.5 ohm
SAFE TO CLOSE INPUT
A control voltage to the INP Safe To Close input must be applied
before a CB close pulse can be output.
If the CB reclose output pulse is delayed for 60s by the INP Safe
to Close input is not being applied, the 1B230 will go to lockout.
DRIVE TO LOCKOUT INPUT
Application of a voltage pulse to the INP Drive To Lockout input
will drive the 1B230 to the lockout condition.
Function Details
RESET RELAY FROM LOCKOUT
The 1B230 may be reset from the lockout condition in 3 ways:
1. Application of a voltage pulse to the INP Reset Lockout input;
2. Pressing the front panel reset button;
3. Interruption of the auxiliary supply for >10s.
RECLOSE OPERATION
Front panel switch selection of Single (1) or double Shot (2)
Front panel switch selection of Lockout (L) or Auto Reset (A)
The contact closure output pulse (RLY CB Close Sig) is of 2
second duration.
TIME DELAY SETTING RANGES
Dead Time 1 (Reclose 1): 5 to 180s

Timing Sequence

Description of Operation
The 1B230 function is determined by the setting combination of five (5) switches located on the front
panel. The following sections provide a description of each operating combination & a logic flow chart.
The function provided by the Live Line switch is to ensure that the Line voltage is zero before a
reclose can be attempted. Switching this to the “Out” position removes this safety feature. Some relay
versions do not have the hardware to support this feature & switch 3 position is designated “Not Used”
which has the same effect as “Live Line Out”.
The following table summarizes all of the switch setting combinations & provides a reference to the

3.1 Single Shot, Auto Reset, Live Line Out, Block Instantaneous OFF
1. Once the breaker has tripped and the Protection Trip Contact has closed the A/R in
progress LED will flash and the A/R contact will close, the relay will wait for the setting of
Dead Time 1 to expire, it will then issue a reclose output pulse, the counter will increment
one count and the A/R in progress LED will become steady.
2. If the breaker closes and the protection opens the relay will reset after the Reclaim time
expires and will be ready for the next breaker operation.
3. If however after issuing the reclose pulse the Protection Trip Contact is still present the relay
will drive directly to Lockout. If the Protection Trip Contact has reset but the Circuit Breaker
has not, the relay will wait for the Reclaim time to expire before it goes to lockout.

3.4 Single Shot, Auto Reset, Live Line Out, Block Instantaneous after 1st Trip
With the switch setting depicted above the relay will go through the following operations.
1. Once the breaker has tripped and the Protection trip contact has closed the Block
Instantaneous contact will pick up and the front panel LED will be lit, the A/R in progress LED
will flash and the A/R contact will close. The relay will wait for the setting of Dead Time 1 to
expire, it will then issue a reclose output pulse, the counter will increment one count and the
A/R in progress LED will become steady.
2. If the Protection Trip Contact and Circuit Breaker has closed the relay will wait for the Reclaim
time to expire then the Block Instantaneous Protection LED and contact will reset and the relay
will reset ready for the next operation.
3. If the Protection Trip Contact is still operated after the Reclose Pulse the relay will drive directly
