DOI: 10.1109/tps.2024.3485051
Abstract: In vacuum interrupters, plasma remains between the electrodes after the current zero because of arcs generated by the interruption of short-circuit current. This residual plasma consisting of ions, electrons, and metal vapor affects the insulation… read more here.
