1. A pulse detection system for detecting pulses in an electrical power distribution network in response to a fault, the system comprising:
a feeder;
a power source providing power to the feeder;
a recloser electrically coupled to the feeder and including an interrupter switch and one or more sensors for measuring current and/or voltage on the feeder, wherein the recloser detects fault current and is operable to clear the fault and then perform a pulse testing process that generates the pulses to determine if the fault continues to be present; and
a device having a pulse catching function electrically coupled along the feeder, the device including one or more sensors for measuring current and/or voltage on the feeder, wherein the device detects the pulses produced by the pulse testing process by identifying one or more of a peak current magnitude of the pulses being greater than a predetermined current value, a pulse duration of the pulses being greater than a predetermined time, a predetermined interval between consecutive pulses and a presence of a pulse/inverse pulse sequence.
