| Abstract: | In order to detect the traveling waves in the transmission lines correctly, the principle of singularity detection by using wavelet transform modulus maximum is presented. With the technology of wavelet de-noising, the traveling waves are accurately extracted in the noise background. The validity of the proposed method is verified by the results from simulation. |
