New Method of Distinguishing Nonmetal Grounded Phase in Small Current Grounding System
Yanhua Wang, Yingfeng Chen · Journal of Chengde Petroleum College · 2005
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.
