A new traveling wave fault location method for earth faults is proposed based on propagation time delays between aerial mode and earth mode acquired by multi-measuring points on transmission line. Using phase-mode transformation theory and the theory of wavelet singularity detection to achieve the algorithm of propagation time difference detection. The JMarti model is used to build the system simulation model in the EMTP. The final results show that the method has high reliability and precision.
