摘要
对小电流接地系统单相经过渡电阻接地后三相对地电压、中性点对地电压的变化进行分析 ,并对绝缘监察系统的灵敏度及非故障相对地电压大于
An analysis on the change of the three-phase to ground voltage and neutral point to ground voltage is done in this paper as the single phase grounded via a transition resistor in neutral indirectly grounded system. The sensitivity of the insulation supervisory system , the range of healthy phase to ground voltage which is greater than 3 multiple phase voltage and its maximum value are analyzed as well.
