Traveling wave fault location in power transmission systems : an overview

الملخص EN

Accurate location of faults on power transmission systems can save time and resources for the electric utility industry.

Line searched for faults are costly and can be inconclusive.

Accurate information needs to be acquired promptly in a form most useful to the power system operator.

In order to attain this accuracy, a complete system of fault location technology hardware, communications, and software can be designed.

The manuscript describes the phenomenon of traveling waves generated due to different faults in transmission lines and how these waves can be used to obtain precise fault location in very little time.
