Faulted feeder identification and location for a single line-to-ground fault in ungrounded distribution system based on principal frequency component

Archives of Electrical Engineering, 2020
When a single line-to-ground fault occurs in the ungrounded distribution system, the steady-state fault current is relatively small for fault analysis and the transient fault current is observable, which can be used for faulted feeder identification and ...
