| Abstract: | This paper introduces a method of one-end fault distance measurcment in transmission line, according to the theory of singularity detection in wavelet transform and the theory of travelling wave. Compared with traditional method, the method excellents in using less hardware, free of influences in both-end-synchronous clock, and low deviation in fault location. |
