抄録(英) | Arc discharges often lead to serious contact failures when electrical contacts operate. Although values of so-called minimum arc current for various contact materials are often referred to as the lower limit over which no arc discharges are expected to occur at contact operations, damages apparently related to arc discharges can be observed even when contacts operate in very-light load region. In this paper, arc occurrence rates are measured for Ag and Pd contacts operated in a DC resistive load circuit. Based on the obtained results, it is confirmed that arc certainly occurs at current levels lower than the conventional minimum arc current value for each of the tested contact materials. Arc occurrence rate in general comes close to 100% at the conventional minimum arc current level. Accordingly, careful attention should be paid to use of the term "minimum arc current" in order to avoid misinterpretation thereof. |
