A scheme of high accurate fault location with high frequency in fault transient signals on non direct ground neutral system is proposed. The general concept of wavelet neural networks is introduced, and the time series wavelet neural network model is proposed for discrete time series signal analysis. Then according to the characteristic of fault transient signals, the adaptive time series wavelet neural network is applied for the fault location on non direct ground system, and the EMTP simulation results illustrates the efficiency and practice of the method proposed.
