Abstract

Formerly, there were pulse radar and Murray loop bridge in cable fault location method that is applicable for branch line. Those methods need terminal connection at far end. Therefore, it is trouble in fault location for branch line. Pulse radar is applicable for only high resistance ground faults and Murray loop bridge is applicable for only low resistance ground faults.<br> We developd current detection pulse radar and tested it. In high resistance ground fault location measured result includes discharge delay error. Therefore, we proposed an error correction method and confirmed it. And we designed a new cable fault location method of pulse radar and tested it.
