A new approach to accurate fault location considering the effect of mutual inductance by multi-terminal signals

Accurate fault location of transmission line is of great importance for power industry. With the increase of overhead lines with mutual inductance, the effect of mutual inductance on the accuracy of fault location becomes more and more serious. In this paper, a new accurate fault location system considering mutual inductance by multi-terminal signals is discussed, and corresponding simulation results are given, and a comparison is made as well. In addition, the hardware configuration is presented.
