Abstract

This paper addresses the application of wavelet transform in the identification of transient and permanent faults by processing the fault generated high frequency current transient. The presented method can be utilised to achieve adaptive reclosure which means only the transient fault can activate the reclosing operation. An identification unit is designed to capture the high frequency component generated by a fault arc and the wavelet transform is used to extract the high frequency noise generated by the fault arc and distinguish between the transient and permanent fault
