1. IntroductionSingle-phase grounding is a common fault in distribution networks, and small current grounding faults are difficult to detect promptly because they do not disrupt the continuous supply of electricity. However, if the distribution network is in a faulty state for a long time, it may evolve from a single-phase grounding fault to an interphase short-circuit fault, resulting in power safety accidents [1].
