| 摘 要： | 介绍了小电流接地系统中发生非金属性单相接地时接地相判别的新方法,即在中性点不接地系统中,对地电压最高相的下一相为接地相;在中性点经消弧线圈接地系统中,对地电压最高相的上一相为接地相.并指出相关教科书中考虑不周之处,为正确判别接地相提供必要的理论依据.

| Abstract: | This paper introduces the new method of distinguishing nonmetal grounded phase in small current grounding system.That is,the next phase of maximun voltage is grounding phase in neutral point non-grounding system;the last phase of maximum voltage is grounding phase in arc suppression coil grounding system.It indicates the deficiency in related textbook,and essential theory base is supplied for the distinguishing of grounded phase. |
