摘要
本文探讨了1000伏以下中性点接地供电系统适用接零保护;同一系统中保护接地和接零不能同时采用;
In this paper the questions about protective zero connection is suitable for lower than 1000V power system ,protective grounding and zero connection cen not be used in one system simultaneously and prteetive grounding is suitable for the system in which the neutral point is unconnected with grounl have bee discussed.
