In previous paper, the noise cancellation technique was introduced to identify the reflective waves for fault location in noisy environment. This technique was based on the correlation of wavelet coefficients of stationary wavelet transform at multi scales. This paper describes how to apply it for fault location on underground power cable systems. The fault location algorithm is tested by simulation on real power cable systems. Simulation results proved it can detect and locate in very difficult situations.
