A novel single‐phase grounding fault voltage full compensation topology based on antiphase transformer

Abstract Multi‐tap and multi‐capacitors type arc suppression coils are commonly used in distribution systems. Due to their low compensation accuracy and limited arc suppression capability, it is hardly to avoid personal safety accidents and wildfires absolutely. In this paper, a novel single‐phase g...
