摘要
分析了三相四线制供电系统中 ,中线完好无损时造成中性点电位偏移的原因及其后果 ,指出在三相四线制进线的总电源盘处加装星形联结的三个容量相等的电容器 ,实现对负载中性点电位偏移的实时监控 。
This paper analyzes the reasons and consequences of resulting in neutral point drift under the undamaged condition of neutral conductor,and points out that the phenomenon of drift of electric potential of neutral point of load can be supervised and controlled in time by installing three star connection capacitors of same capacity in the master source plate of entering of wire of three-phase four-wire system.
