1. A system for reclosing open alternating current circuitbreakers in a power substation, the system comprising:

  • at least one bus having at least two feeders wherein each feeder has at least one alternating current circuit breaker; and

    a programmable controller having a plurality of inputs and a plurality of outputs wherein each alternating current circuit breaker of the at least two feeders is coupled to one of the plurality of outputs wherein the programmable controller is programmed to detect whether an alternating current circuit breaker has been open for for a first time period, and, if not, detect whether the circuit breaker has been closed for a second time period, and if so, enable a reclosing cycle wherein the programmable controller is programmed to detect whether a relay operation has occurred to cause the circuit breaker to open, and, if so, initiated a timer to establish a reclosing window of time during which the alternating current circuit breaker may be closed, and output a command signal to the alternating current circuit breaker to close during the reclosing window of time.
