Abstract
A highly accurate fault location method for series-compensated double-circuit transmission lines having series compensation devices and metal oxide varistors (SC&MOV) at first and second terminal ends is provided. Synchronized or unsynchronized current phasors and local voltage phasors are used as input to the fault location method. The voltages and currents at the fault point are formulated as a function of the unknown fault location. Boundary conditions for the particular IED-determined fault type are used to derive the fault location formulas.
