Generally, fault location in underground transmission cable system is very difficult because of many noises. Therefore, a method to remove the noise in power cable systems is proposed by applying noise cancellation technique based on the correlation of multiple scales of the transients using wavelet analysis. After the noise cancellation, the transient signals reflected from fault point and other end of cable can be used to locate the fault using single-ended approach when the single line-to-ground fault occurs in underground transmission cables. This paper proposes a fault location algorithm using noise cancellation technique in noisy environment. This algorithm is simple and straightforward. The simulation results of 225 fault conditions including different fault resistance, fault location and fault inception angle and real test results prove it can accurately locate the fault in very noisy situations when the single line-to-ground fault occurs in the system.
