영문 초록

This paper is aimed to analyze arc hazard for time and frequency domains using a hardware and a monitoring program to select NI-9215 of NI comp., which can be used in developing electrical equipment, to analyze and detect the 1∼1000㎃ and 1∼100A current signals. In this paper, when the breaker simultaneously inputs arc(UL 1699), leakage current and current(heat loads), the characteristics of arc were analyzed by the leakage current and current signals on electric wire which were installed, and also analyzed by the changes of RMS, instantaneous of waveform value in time domain and frequency. As results of the experiments by NI-9215, the arc current waveform showed the same characteristic in all measurement points of heat load. But the leakage current waveform and RMS was different in each measurement point. When arc occurred, the leakage waveform and RMS were of current value increased.
