Abstract. The AC series fault arc tests are conducted by a self-design platform according to several common test standards for fault arc circuit breakers in this paper. Compared with the no-arc current waveform, the current of fault circuit has shoulders when the current passes zero, and the current of fault circuit is lower than the no-arc current. A united method of the wavelet transform (WT) and the information entropy (IE) is proposed to distinguish the fault and normal circuit. By the WT of arc current and the analysis of multiple-sampling, the results reveal that the arc fault frequency bands (FB) range is (625, 1250) Hz. The wavelet component D3 of arc current and its wavelet energy (WE) have large value during the arc period. The wavelet energy of no-arc circuit is lower than 0.006. The IE is bigger than 1 in the fault circuit. Therefore, the FB, WE, IE can be chosen as the fault characteristics to detect the fault circuits.

“…Then, difference between arc and permanent faults will be achieved by comparing the estimated amplitude of arc voltage with a given threshold. The basic principle of arc fault detection in [7] is based on detecting the rate of change of line current during an arc fault and comparing it with a threshold. In [8], the signals of adaptive frequency bands can be extracted from line current waveforms to compare the maximum magnitude with a threshold to detect arc faults.…”

“…DC arc faults can occur in the electrical systems of electric vehicles, ships, aircrafts, photovoltaic plants, variable speed drives, utility energy storage units, and any other applications that involve high voltage dc buses [1]- [3]. If not detected and extinguished on time, the arc faults could spread to adjacent circuits and endanger the power sources, control systems, or even cause explosions in a confined space due to the growing arc pressure.…”

DC arc fault detection is important to provide circuit protection and improve system reliability in applications with high voltage dc bus. In this paper, current change in time domain and normalized RMS value from wavelet decomposition are selected as arc signatures representing the randomness and chaotic nature of arcing. A detection algorithm is then proposed utilizing these two arc signatures to differentiate between arc fault and normal condition. Lastly the detection algorithm is realized on a digital signal processing board and is tested to verify its effectiveness. Experiment results show that the proposed detection algorithm can detect arc fault in a timely manner and is free of nuisance trip from normal circuit operations such as load change condition.
