Digital fault location for high resistance grounded transmission lines

This paper demonstrates that the presence of multiple load taps cannot be n eglected for single-phase-to-ground fault location. A new method has been d eveloped taking this into consideration, that can be applied to correct the location error due to intermediate power sources. Then fault location meth ods for parallel double-circuit two-terminal transmission linesare discusse d. Finally, a new fault location method is proposed for high-resistance gro unded double-circuit transmission lines with three terminals.
