Abstract

Rotary arcs driven electromagnetically by a fault or load current are used for interrupting duties at distribution level and as preheaters for high temperature chemical reactors. One such form of rotary arc device is the helical arc unit. The paper investigates the electrical interaction between repeated arc short circuiting and the connected network or power supply. The results are relevant to medium and high voltage AC interrupters and chemical processing preheaters
