| Abstract: | The characteristics of the single phase current leakage faults in small current ground system are analysed. A new method of selectively examining the faults is proposed, and it is named as "time sequencing phase comparison" method. After the basic principls and characteristics of the method are discussed, a simple circuit is implemented, and its working priciple is described. Finally, the conclusion based on the experiment results in laboratory and on a 6 kV power line is drawn. |
