The voltage and current signals include line power frequency voltage and current signals and zero-sequence voltage and current signals; the traveling wave module uses The method is to receive the fault information sent by the processing module, then obtain the head time of the traveling wave current at the time of the fault, and send the head time of the traveling wave current to the processing module. The invention can accurately locate the fault point, and at the same time improves the accuracy rate of single-phase ground fault judgment, guides the operation and maintenance personnel to patrol the line, and shortens the time for finding and repairing the fault.
