Abstract
The influence of inrush current on the grounding resistance at the neutral point when the single-phase grounding fault occurs in the neutral point grounding system through small resistance is analyzed,as well as the role of inrush current monitoring for the grounding resistance in working condition assessment for the resistance.The monitoring and recording methods for the inrush current are recommended,and the working condition of the grounding resistance is analyzed.
