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

Gong-kuang zidonghua, 2022
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.
