Analysis of Neutral Grounded Though a Resistance

简单介绍了中性点接地的几种方式后 ,详细分析了中性点经电阻接地系统的单相接地电流和零序电压的特点 ,给出了该系统工频谐振过电压与故障电流的关系式 ,并进一步分析了该系统的特点。

This paper analyses the current and zero sequence voltage of a single line to ground fault with its neutral grounded though a resistance,and puts forward the formulate of the resonance voltage and the grounded current. Finally,the paper deals with the characteristics,influence on the protection and applied conditions of the system.
