| Abstract |
According to the Fire Statistical Yearbook, Electric arcs, such as ignition sources, are a high proportion in Korean fire accidents. Because it is important to detect the arcs prior to the fire accidents, sensors and frequency analysis have been studied to detect them. The arc detection techniques based on the sensors and frequency analysis are limited in location search and reliability in arc detection, respectively. Therefore, it is necessary to study an improved technique for detecting the arc. This paper proposes an arc detection technique that can improve the location search and the low reliability in the arc detection using the voltage fluctuations. The experiments were conducted to obtain the voltage fluctuations from the measured voltage waveforms under conditions with or without an arc for the loads defined in IEC 62606, thereby checking the presence of the arc. We confirmed that the proposed arc detection technique can detect a series arc in electric equipment. |
