Abstract

The authors have observed the relationship between waveform of electromagnetic noise and change of surface for opening Ag-Pd electric contacts. In case of Ag-Pd electrodes continuous noise is observed in the whole period of arc discharge in both current polarities. Fluctuations of arc voltage and noise are large in the middle part of arc discharge duration. The noise decreases in the later half. The authors proposed a classification of noise waveforms and pattern of surface changes. As these results patterns of noise waveform and changes of electrode surface at various circuit conditions are classified into three categories. In this paper the authors showed the correlation between pattern of noise waveform and the change of electrode surface.
