Wavelet analysis of arcing fault phenomena with particular reference to development of new protection and control techniques

In this paper, the faulty transients generated by primary and secondary arcs are analysed using wavelet transform with particular reference to the development of new protection and control techniques. Daubechies D4 wavelet transform is adopted and the numerical analyses reveal that certain wavelet components can be effectively used as the features to detect and identify faults in transmission systems. The outcome of the study clearly indicates a novel way to advance the development of power system protection
