| Abstract: | This paper discusses the operation status of neutral grounding in urban power distribution systems of Henan province. As the ratio of cable increased in urban power distribution system, some problems are pointed out in traditional operation mode of neutral grounding. This problems have great influence on power supply reliability, equipment and personal safety. Based on the analysis and operation experience, the proposal of solving the problems is brought forward. |
