Abstract :
A finite transform based algorithm has been developed for digital distance protection of power system transmission lines. This paper presents the investigation results of performance affected by sampling rate and window length. Improved performance of both operating speed and reach accuracy can be achieved by optimum selection of these parameters.<>
