摘　　要：中性点不接地系统或中性点经消弧线圈接地系统在发生单相接地和非线形谐振时出现虚幻接地现象区别不是十分的明显,所以在发生单相接地或谐振时,现场值班人员应根据当时的所发生的现象进行正确的判断,防止误判断发生设备事故。The neutral point ungrounded system or neutral point grounding system though arc suppression coil,in case of single phase ground and non-linear resonance the difference of virtual ground phenomenon is not very clear,so in case of single phase ground or resonance,field duty personnel should make correct judgement based on the phenomenon occurred to prevent the occur of equipment accident due to incorrect diagnosis.

关 键 词：中性点不接地系统 单相接地 谐振
