Active arc suppression device based on voltage‐source convertor with consideration of line impedance in distribution networks [PDF]
IET Power Electronics, 2021 Abstract In the non‐effectively grounding distribution system, residual current under single‐line‐to‐ground (SLG) fault threatens the safety of human being and power supply equipment. Active arc suppression device has been proved to be effective for SLG fault arc suppression when the line impedance is ignored.
