| Abstract: | Nowadays the 10 kV power network neutral point grounding way mainly adopts two ways：by the arc suppres- sion coil grounding and the small resistance grounding mode. Combining with the current situation of the development of power grid, the application background, operational characteristics of two kinds of indirect grounding way and the failure characteristics of single - phase grounding fault occurs each has carried on the detailed analysis, Combined with the fea- ture of its fault, the appropriate fault line selection methods is given, and the matters for attention in the operation of the two systems has carried on the Briefly analysis. |
