Abstract:
Detection of faults in an electrical power distribution network that includes measuring current flowing through a recloser in a feeder line, detecting a fault current indicating a fault is present in the feeder line, and opening a switch in the recloser in response to detecting the fault current. A first pulse having a first pulse duration time is generated, and the current flow in the recloser during the first pulse duration time is analyzed. A second pulse having a second duration time that is longer than the first pulse duration time is generated if it is determined that no fault current exists during the first pulse duration time, and the system voltages and the current flowing through the recloser after the second pulse duration time is analyzed for the presence of the fault.
