GE IS200VPWRH1A IS200VPWRH1AFB MARK VI board subassembly

Description

GE General Electric Technical Specifications: IS200VPWRH1A

The current supervision feature is used to limit breaker wear. When fault current exceeds user-programmed

IS200VPWRH1A levels, it reduces the number of reclose shots permitted.

Once a reclose sequence is initiated, the maximum current measured on any phase is compared to the set

IS200VPWRH1A point current levels. The relay then determines the maximum number of shots allowed or whether the scheme

goes immediately to lockout. The lowest number of permitted shots, whether set by the MAXIMUM NUMBER OF

RECLOSE SHOTS setpoint or the current supervision feature, always takes precedence unless current supervi

sion takes the scheme to lockout. Lockout has the highest priority. Once the current supervision feature has

reduced the total number of shots, a subsequent shot can still reduce the limit further.

The 760 autoreclose scheme can be programmed to maintain coordination of overcurrent elements with a

IS200VPWRH1A downstream recloser. If a downstream recloser is programmed to use different protection settings for different

reclose shots, it may be necessary to change the protection settings on the 760 each time the recloser oper

ates. To ensure that protection coordination is maintained, each 760 reclosure shot must be coordinated with

each downstream recloser shot. In addition, the 760 reclose shot counter must always match the recloser shot

counter. When a fault occurs downstream of the recloser and the 760 feeder breaker does not trip and reclose,

the 760 reclosure shot counter must still be incremented.

Once enabled, this scheme assumes an external reclose operation has occurred when the feeder phase or

IS200VPWRH1A neutral current exhibits a step increase in magnitude, due to fault current, followed by a step decrease in mag

nitude, due to a recloser opening. After the first detection of an external reclose, the shot counter is incre

mented by one, protection settings are changed, and the autoreclose scheme reset timer is initiated.

If the fault is permanent and the recloser continues to trip and reclose, the coordination feature will continue to

increment the shot counter. If this continues to the maximum number of shots programmed in the 760, the

autoreclose scheme will go to lockout.

If the fault is transient, then the autoreclose scheme and shot counter will eventually be reset by the normal reset mechanism.
