ABSTRACT:
A timing controller which supervises the reclosure of a fault responsive circuit breaker which includes a plurality of selectable switches for developing signals representing the reset and reclose delay times for the recloser relay operatively associated with the fault responsive circuit breaker; a plurality of multiplexers for receiving the signals developed by the selectable switches and for developing serially formatted digital words in accordance with such signals for delivery to an output controlling multiplexer; a first counter assembly for regulating the output of the output controlling multiplexer in accordance with the condition of the recloser relay; a storage device for receiving and storing the output of the output controlling multiplexer; and a comparison device for comparing the stored output of the output controlling multiplexer with a second counter assembly which develops a timed output signal. Successful comparison of these signals produces an output signal for supervising the operation of the recloser relay.
