A method of detecting a location of a fault in a distribution line having a first and second terminal and a line segment disposed therebetween is provided. The method includes identifying synchronized voltage and current phasors at the first and second terminal prior to and during the fault, calculating equivalent sequence components for the voltage and current phasors, locating a virtual load point on the line segment, and calculating a voltage at the virtual load point. The method further includes calculating a compensated load current at the first and/or second terminal based on one or more of the current phasors prior to and/or after the fault, and calculating a distance from the virtual load point to the fault based on the voltage at the virtual load point, the compensated load current, and one or more of the equivalent sequence components to detect the location of the fault.
A fault detector for detecting a location of a fault in a tapped power distribution line having a first terminal, a second terminal, and a line segment disposed therebetween, the fault detector comprising:
