| Abstract | (in Japanese) | (See Japanese page) |
| (in English) | Since electromagnetic (EM) noise resulting from an arc discharge disturbs other electric devices, parameters on electromagnetic compatibility, as well as lifetime and reliability, are important properties for electrical contacts. To clarify the characteristics and the mechanism of the generation of the EM noise, the current fluctuation as current noise frequency generated by slowly breaking contacts was investigated experimentally using Ag material. To reveal the characteristics as pure clean surface contact operation, the arc only at the operation of the first contact break was measured. From the time-frequency domain characteristics of current noise, it was clarified that the peaks of current noise due to voltage fluctuation at 30MHz and 70MHz band arise at the arc discharge. It is demonstrated experimentally that peak frequency of current noise is independent of supply voltage. As the supply voltage increases, peak value of current noise increases. | |
