Flexible arc suppression method for single-phase to ground fault in distribution network based on Z-type grounding transformer

Flexible arc suppression method for single-phase to ground fault in distribution network based on Z-type grounding transformer

The coal mine power supply and distribution system usually adopts the neutral point non-effectively grounded method. Most of the power supply lines in this method use cable lines. The underground power supply system is complex and uses many voltage levels. When a single-phase to ground fault occurs,...
