GE General Electric Technical Specifications: IS200VPROH1BCB

The 760 has a very flexible autoreclose scheme that allows for the many different control strategies typical of

utility applications. Up to four reclosure ‘shots’ are possible with separately programmable ‘dead times’ for

IS200VPROH1BCB each shot. Reclosure can be initiated from any 760 overcurrent element or from external sources. Between

each shot, overcurrent protection settings can be adjusted in order to co-ordinate with downstream devices. To

prevent breaker wear, a ‘current supervision’ feature can reduce the number of shots when the fault current is

high. A ‘zone co-ordination’ feature can maintain protection coordination with downstream reclosers. Logic

inputs are available for blocking and disabling the scheme.

Front panel LEDs indicate the present state of the autoreclose scheme. Note that display message group A1

STATUS \ AUTORECLOSE can also be accessed to determine the present state of the autoreclose scheme.


The scheme is enabled and may reclose if a trip occurs.


The scheme is not enabled and will not reclose until the scheme is enabled.

IS200VPROH1BCB RECLOSURE IN PROGRESS: An autoreclosure has been initiated but the breaker has not yet been closed.


The scheme has gone to ‘lockout’ and must be reset before further recloses

are permitted.

The reclosure scheme is considered enabled when all of the following conditions are true:

  1. The AUTORECLOSURE FUNCTION setpoint is set to Enabled.
  2. Either a 52a or 52b contact is installed and has been programmed to a logic input function.
  3. Neither the ‘Block Reclosure’ nor ‘Cancel Reclosure’ logic input functions are asserted.
  4. The scheme is not in the lockout state.
  5. The AR BLOCK TIME UPON MANUAL CLOSE timer is not active.

IS200VPROH1BCB Following is a simplified description of how the autoreclose scheme works. See the application example sec

tion and logic diagrams at the end of this section for further details.

A fault occurs resulting in an overcurrent element tripping the circuit breaker and initiating a reclosure. Once

the breaker is detected open a ‘dead timer’ is started. Once this timer exceeds the value programmed for the

reclosure 1 setpoint DEADTIME BEFORE RECLOSURE, the shot counter is incremented and a breaker closure is ini

IS200VPROH1BCB tiated using the ‘2 Close’ output contact. At the same time, overcurrent element characteristics are modified

according to the reclosure 1 setpoints.

If the fault is permanent, subsequent overcurrent element(s) will trip and initiate reclosure. The scheme will

eventually go to lockout when the MAXIMUM NUMBER OF RECLOSURE SHOTS has been met and another trip

occurs. If a breaker failure condition is detected at any time during operation, the scheme will again go straight

to lockout. When in lockout, the 760 disables the reclose scheme and returns all protection settings to their ini

tial values. To re-enable the autoreclose scheme the relay must be reset via the front panel reset key, the

‘Reset’ logic input function, communications, or by a manual close operation. The latter resets the scheme only

after the AR BLOCK TIME UPON MANUAL CLOSE timer expires, and no overcurrent elements are picked up.

If the fault is transient in nature then no overcurrent element(s) will trip after the breaker has closed. The

scheme will automatically reset when the reset timer, started upon the first reclosure initiation, exceeds the set

point AUTORECLOSE RESET TIME. This autoreclosure reset returns the shot counter to zero and all protection set

tings to their initial values.

An anti-pumping feature is built into the reset mechanism. Otherwise, breaker ‘pumping’ could occur when

the fault level is between the initial overcurrent pickup level and the adjusted overcurrent pickup level for a

reclosure shot. It prevents a permanent fault from continuously repeating the trip breaker, initiate reclose, close

breaker, automatic reset of autoreclose scheme, trip breaker sequence. If this condition is detected the anti

pumping feature returns protection settings to their initial values without resetting the shot counter. The relay

will then continue to trip and reclose until lockout is reached.
