Abstract: High-impedance faults (HIF) occur frequently in resonant grounding systems and are difficult to detect. Thus, an effective HIF feeder identification technology is urgently needed. This paper establishes an HIF equivalent circuit in a resonant grounding… read more here.

DOI: 10.1109/tpwrd.2021.3074217
Abstract: A novel fault location scheme using feeder terminal units (FTUs) for high-impedance grounding faults in resonant grounding systems (RGSs) is presented. The parallel resonance for a high-impedance fault (HIF) in an RGS with inverter-interfaced distributed… read more here.
