Faulty feeder detection of the single-phase-to-ground fault in resonant grounding distribution system (GRDS) is faced with huge challenge due to weak fault current, and the existing methods indicate low reliability in some situations. For improvement, a new method based on composite factors is proposed in this paper. The composite factor is composed of transient factor and steady-state factor which are defined respectively according to transient process and steady-state component in the fault zero-sequence equivalent network. The transient factor of faulty feeder is much greater than those of ...
