Abstract

One or more faulted conductors are identified in a power transmission system having at least two power-transmitting conductors and a fault location is determined. The methods for identifying faulted connectors and determining fault location include steps of monitoring current signals which are representative of currents in the conductors at a generally common location within the power transmission system; filtering the current signals; determining a maximum rate of change of each filtered current signal within a predetermined time interval after the fault event has commenced; and calculating a ratio of a pair of the maximum rates of change of the filtered current signals. For fault classification, the ratio is compared against a discrimination factor to identify the one or more faulted conductors. For fault location, the calculated ratio is compared against the calibration data to determine the distance from the connection terminal of the faulted conductor to the fault location.
