Abstract :
The real-time digital signal processing (DSP) implementation of a wavelet analysis filter bank (WAFB) to identify a high impedance fault (HIF) is presented. HIFs and capacitor bank switching events are simulated by using the Electromagnetic Transients Program (EMTP). The simulation results are used as the input signal for the implementation of a wavelet analysis filter bank. Results demonstrate that the wavelet analysis filter can be used as an element in a real-time HIF detector for fast and accurate identification of distribution HIFs
