Abstract This paper mainly aims at the ground fault analysis of 35kV ungrounded systems in different places the 35kV overall voltage system and different wire current will occur, the fault characteristics are introduced through the establishment of equivalent circuit. At the same time, the protection action of this kind of fault is verified through analyzing the data of protection device and recorder.
