Abstract :
Electric arcs in electrical DC systems represent both an enormous challenge to switchgear (switch arc) and a serious hazard to humans and the whole system (fault arc). Hitherto existing literature states an negative impact of a parallel capacitance on the arc existence. For low voltage DC systems the behavior of free burning arcs in air is analyzed. The formation of arc-oscillations due to a parallel capacitance is investigated. Several dependencies between total current, arc-length, electrode material and value of the parallel capacitance are outlined.
