Estimating accurate phasor calculations and selection of best fault data window are the basic requirements of any fault location algorithm. This paper highlights the issues with conventional Fourier transform based filtering techniques to compute fundamental components. It also discusses the effect of RDFT on fault location especially in case of short duration faults. The paper introduces an improved fault location scheme based on Prony analysis. The comparison of RDFT filter and Prony analysis for the computation of fault location is also presented. Performance of the proposed scheme is showcased with the help of case studies and practical data.
