| Abstract: | To the weakness of resistance fault location method, the history of traveling wave fault location on high voltage transmission line is reviewed. The development of modem traveling wave fault location, the key parts of fault location system, such as sensor, high speed data collection and GPS unit etc., are presented. The problems encountered in real operation are summarised according to field investigation and the solution ways are supplied. The paper also give suggestions and perspects of traveling wave fault location in transmission line. |
