电压互感器二次回路N600多点接地查找及处理

The Search and Dispose of More Grounding of Voltage Transformer Secondary Circuit N600

从理论上分析了电压互感器二次回路多点接地的危害,并结合台山电厂220kV变电站查找N600多点接地的实际例子,介绍了N600多点接地的判断及查找方法,并提出了防范措施。

This article analyse the influence about more grounding of voltage transformer secondary circuit,and take the search of taishan 220 kV power plant＇s N 600 grounding as an example,introduce the methods of judgement and search,and also give advances to keep from happening.
