摘要: When a disturbance (for example, lightning strike) occurs on high-voltage overhead transmission line, the line must be checked for any possible damage. If distance-to-fault is known, crews can quickly dispatched necessary repair. The present invention fault location method and system that uses filtered, time-synchronized positive- or negative-sequence voltage current measurements from both ends of to determine exact distance with respect either end.
