Abstract :
A new signal processing algorithm for arcing faults detection based on the high frequency current transient is presented in this paper. In transient faults, arc current extinguishes and then ignites, and this periodically disturbs fault current. After several cycles, when transient signals by the fault decay a lot, the arc disturbance can be identified by the wavelet transform. The feasibility of this algorithm has been tested by computer simulation
