| Abstract: | A new fault location algorithm based on the transient data from both ends of the transmission line is described. The algorithm adopts the distributed parameter transmission model and the fault andysis in frequency domain. The algorithm is tested using EMTP-generated data and the results shows that it is highly accurate and practical. |
