A new wavelet based fault detection, classification and location in transmission lines
Voltage and current signals from both the ends of the line are analyzed with Wavelets. Fault detection and classification are achieved in half cycle using d-coefficients. Approximate coefficients are fed to ANN to locate the fault on the line. Proposed scheme has been tested successfully for various type and nature of faults. The variation incidence angle has have no effect on performance of the scheme.
