Abstract

The correlation between the voltage course and the anode surface temperature was studied by combined optical and electrical measurements. Performed analysis of the temporal evolution of electrical and optical signals reveals that in the case of constricted anode attachment a clear correlation between electrode surface temperature and arc voltage occurs. The results of the study provide new opportunities for qualification of electrode materials for switching applications.
