ABSTRACT:
A method of locating a phase-to-ground fault in a radial distribution system with a tapped load. The method includes determining the positive-sequence impedance from the residual current, the residual current compensation factor and the phase-to-ground voltage of the faulted line. The positive-sequence impedance is then used to determine the distance to the fault.
