ABSTRACT:
A relay spare circuit for a recloser relay provides an output signal selected to occur during a particular segment of the reclose cycle of a fault-responsive circuit breaker. A set of switches is provided to select which of a plurality of available recloses are to be used and where in the resulting reclose cycle the relay spare is to operate, and a logic circuit is provided which compares the selected switches with a counter responsive to advancement of the recloser relay through the reclose cycle, to provide the relay spare output signal at the selected point in the reclose cycle.
