Abstract(in Japanese) (See Japanese page)
Abstract(in English) Arc discharge generated by breaking electrical contact is considered as a main source of an undesired electromagnetic (EM) noise. Since the EM noise resulting from the arc discharge distrubs other electric devices, electromagnetic compatibility (EMC), as well as lifetime and reliability, are important parameters for the evaluation of electrical contact. In order to clarify mechanism of generation of the EM noise, feature extraction of bridge and short-time arc waveforms generated by slowly breaking Ag contact is discussed experimentally in this paper. It is revealed that as the arc voltage of the short-time arc is higher, its duration becomes longer. From the APD of the bridge waveform, the duration is shorter and the arc-voltage is low, when the time in which the temperature at the a-spot is melting point is short.
