The work is devoted to the aspects of using phase methods for measuring distances to faults in a power line. The existing phase methods are shown and discussed. It is established that spectral leakage is one of the problems of spectral analysis. An algorithm for spectral analysis based on a change in the width of the analysis window is proposed. It is shown that the proposed method provides an increase in the accuracy of determining the amplitudes of the total signal components.
