Abstract Powerline faults are responsible for major bushfires around the world where arcs provoked from ground faults are common causes for igniting such fires. The grounding techniques (mainly resonant grounding) used in distribution substations and arc suppression devices play a crucial role for compensating fault currents in order to extinguish arcs so that the likelihoods of power... https://uyqvimjermg12l.timeblog.net/70688317/occurrence-of-equatorial-plasma-bubbles-during-intense-magnetic-storms
