In this paper, magnitude and shape of the current flowing on AC line was analyzed when series AC arc and parallel AC arc occur. It was confirmed through experiment that when series AC arc occurs on the AC line, the shape of the current changes more than the magnitude of the current. In addition, in the case of the parallel AC arc, it was confirmed from the experiment that shouldering effect occurred and the line current flowing on the AC line had a distorted current waveform comprising multiple harmonic components, instead of a sinusoidal waveform. To detect series AC arc and parallel AC arc, Zero crossing period (ZCP) and Fast Fourier Transform (FFT) result were used. As a result of analyzing the arc detection capability when the series AC arc and the parallel AC arc occur, in the case of series AC arc, arc detection in time-domain was more effective than in the frequency-domain when the line current was small and detection capability was similar at each domain when the line current was large. In the case of the parallel AC arc, it was confirmed from the experiment that the parallel AC arc was more easily detected than the series AC arc, because the parallel AC arc generates a more distinct current change comparing to the series AC arc.
