摘要：

High impedance faults on the multigrounded three-phase four-wire primary distribution system cannot be detected effectively by existing overcurrent sensing devices. This paper summarizes some of the staged fault test results of different detection methods applied to the Taipower primary distribution system. The methods include the wiring modification of the ground overcurrent relay, the ground product relay, the ratio ground relay and the harmonic current approach. The test results are reported and discussed for the purpose of providing a practical evaluation of high impedance fault detection. © 1990.
