Secondary Arc Extinction in Extra High Voltage Systems Using Grounding Switches

Diyala Journal of Engineering Sciences, 2014
Long Extra High Voltage (EHV) transmission systems tend to bring a pronounced state of secondary arcing. Therefore, an essential pre-requisite for single-phase-switching application, is the possibility and speed of secondary arc final extinction during ...
