ABSTRACT:
A method of measurement for fault distance determination on two or more parallel HVDC lines connected between two stations with a line fault locator is provided. The fault distance determination is performed by determining the difference in time, via synchronous clocks at each station, between travelling waves, which arise when a fault occurs, reach the two stations. The difference in time is determined by measuring the current associated with the travelling waves and detecting the current at the two stations and on each of the parallel connected lines.
