| Abstract: | It describes on typical fault of single phase grounding during the operation of networks with ungrounded neutral. Through studying the faults and the process of treatment and the reasons,we point out it is important to note the separation be- tween phase and ground and the fault detection of single phase grounding and fault line selection,and the points for attention during long distance power supply and the IT characteristics de- rivatived by neutral line. |
