Claim 2:
3. The method of claim 1 wherein, when only one of the power-transmitting conductors is faulted such that said only one power-transmitting conductor is faulted to ground, and wherein the currents in the power-transmitting conductors are measured at connection terminals thereof located at the selected set of power converter stations, the method further includes:
providing predetermined calibration data which comprises a plurality of ratios of maximum rates of change of current of the first and second power-transmitting conductors, each ratio being representative of a fault at a corresponding distance from the connection terminal of the faulted conductor; and
comparing the calculated first ratio against the calibration data to predict the distance from the connection terminal of the faulted conductor to fault location.
