초록

This paper describes how travelling waves measured at an end of a transmission line can be used for fault location. In this paper a FIR filter which makes' high frequency components much more prominent is proposed. Consequently. the algorithm can distinguishes correlation peaks. A series of simulation studies using EMTP verified that the proposed algorithm can calculate an accurate fault distance in spite of effects of various errors.
