A new fault location method

This paper describes a new fault location method-the weighted Root-MUSIC method. By weighing the results of the double end method based on the travelling wave and Root-MUSIC methods, according to the position of fault point, this method synthetizes the advantages of the two methods. The performance of this method is represented through analyzing the principles of the double end method based on the travelling wave and Root-MUSIC methods. The new method gives an accurate result wherever the fault point lies on the line, and a high sample rate is not needed. EMTP simulations are provided to substantiate the analysis in different fault position cases.
