Abstract

Cette invention concerne des dispositifs de localisation des dérangements sur les lignes de transport d'énergie, qui utilisent des combinaisons de signaux transitoires transmis par conduction et de signaux électromagnétiques transmis par rayonnement, produits soit par l'arc d'un entrefer soit par une décharge orageuse, ainsi que la connaissance du chemin spécifique des lignes de transport d'énergie associées au dérangement. L'instant d'arrivée des signaux transitoires transmis par conduction et générés par le dérangement est repéré par un capteur d'enregistrement des dérangements (FRS). L'instant d'arrivée du rayonnement électromagnétique de bas niveau (VHF/UHF) généré par la formation d'arcs électriques associés aux dérangements sur les lignes de transport d'énergie est repéré par au moins un capteur de détection d'arcs (ADS), localisé à quelque distance de la ligne de transport d'énergie. Les deux capteurs conçus pour repérer les instants d'arrivée des signaux transmis par conduction et par radiation transmettent des données à un analyseur central (PLFLA) de localisation des dérangements des lignes de transport qui reçoit et manipule ces données pour localiser le dérangement sur la ligne.
