Jr. Zhang et al., INTERACTION OF HELICAL ARC DEVICES WITH INTERCONNECTED NETWORKS, IEE proceedings. Generation, transmission and distribution, 143(1), 1996, pp. 89-95
Rotary arcs driven electromagnetically by a fault or load current are
used for interrupting duties at distribution level and as preheaters f
or high temperature chemical reactors. One such form of rotary are dev
ice is the helical are unit. The paper investigates the electrical int
eraction between repeated are short circuiting and the connected netwo
rk or power supply. The results are relevant to medium and high voltag
e AC interrupters and chemical processing preheaters.
