| Abstract: | Based on analysis of the characteristics of pulse phase-comparision method currently used for selective detection of the leakage faults on power lines, this paper presents a new method named as time sequencing phase-comparision. A simple implementation circuit is given.The experimental results in laboratory and on a 6 KV power line show that the method and the circuit have considerable application value. |
