By means of phase-modulus transform of abrupt-changed voltage and current, the modulus maximum is solved by dyadic wavelet transform; by use of points corresponding to modulus maximums at both sides, the moments, when traveling waves arrive the buses, can be determined. By means of comparing the polarity, the reflected waves coming from faulty point and adjacent bus respectively can be well recognized; the ratio of fault distance to full length of transmission line can be calculated by the ratio of the times when initial traveling wave arrives buses at two terminals to the times when traveling wave reflected by faulty point arrives buses at two terminals; finally, by use of locating by tower, the faulty point is determined.
