5.13 RECLAIM TIME
If the protection operates again before the reclaim time has expired, the corresponding sequence counter is
incr
emented. At the same time, any “dead time complete” (….DTCOMP) signals are reset and the logic is prepared
for the next dead time to start when conditions are suitable. The operation also resets the signal that would set the
circuit breaker to close, and stops and resets the reclaim timer. The reclaim time starts again if the signal to set a
circuit breaker to close goes high following completion of a dead time in a subsequent Autoreclose cycle.
If the circuit breaker is closed and has not tripped again when the reclaim time expires, signals are generated to
indicate successful Autoreclose. These signals increment the relevant circuit breaker successful Autoreclose shot
counters and reset the relevant Autoreclose in progress signal.
The “successful Autoreclose” signals generated from the logic can be reset by various commands and settings
options available under CB CONTROL menu settings as follows:
If Res AROK by UI is set to Enabled, all the signals can be reset by user interface command Reset AROK Ind from
the CB CONTROL menu.
If Res AROK by NoAR is set to Enabled, the signals for each circuit breaker can be reset by temporarily
generating an Autoreclose disabled signal according to the logic shown.
If Res AROK by Ext is set to Enabled, the signals can be reset by activation of an external input signal
appropriately mapped in the PSL.
If Res AROK by TDly is set to Enabled, the signals are automatically reset after a time delay set in AROK Reset
Time.
