Break arcs occurring between electrical contacts with copper or silver runners
Haruki Miyagawa, Junya Sekikawa (Shizuoka Univ) EMD2015-4
Abstract (in Japanese) (See Japanese page) 
(in English) Copper or silver arc runners are fixed on silver electrical contacts. Break arcs are generated between the contacts in a DC high voltage circuit. Circuit current when contacts are closed is 10A. Supply voltage is changed from 200V to 450V. The following results are shown. In cases of copper runners, arc duration increases rapidly because anodes spot stay on the runner when the supply voltage is 350V and over. In cases of silver runners, anode spots run on the runner to extinguish quickly by all supply voltage. Also, silver runners is the shortest arc duration, and copper runners is the longest.
