Abstract

The single phase arc grounding fault is a main fault form in medium voltage distribution networks. It is essential to build an accurate grounding arc model for fault analysis. In this paper, a new grounding arc model is built based on the MATLAB with the arc gap energy-balance theory. Comparing the simulation waveform with the experimental waveform, the results show that this model can reflect the characteristics of actual arc grounding fault effectively. By using wavelet transform, the extract transient information of arc voltage and current. The singularity of the fault signal analysis, to determine the fault moment.
