Location of complex faults on overhead power line

One-end algorithm for locating an open conductor failure combined with an earth fault on power lines has been presented. Two cases: an open conductor failure occurring in front of and behind an earth fault, respectively, have been considered. The sample case with the fault data obtained from ATP-EMTP simulation is included and discussed. Streszczenie. Przedstawiono algorytm do lokalizowania przerwy w przewodzie występującej wraz ze zwarciem doziemnym w napowietrznych liniach elektro-energetycznych, z użyciem pomiarów z jednego końca linii. Rozpatrzono dwa przypadki: przerwa odpowiednio przed i za zwarciem doziemnym. Zamieszczono przykład z zastosowaniem sygnałów z symulacji z pomocą programu ATP-EMTP i przeprowadzono dyskusję rezultatów.
