Abstract

L’invention porte sur un dispositif de détection (D) d'une défaillance dans un réseau électrique (1) comprenant au moins deux équipements électriques (E) reliés par au moins un premier conducteur de puissance (C1), un deuxième conducteur de puissance (C2) et le réseau électrique (1) comprenant également un conducteur commun (Cc). Le dispositif comprend un premier organe de mesure (O1) de la tension de mode commun présente sur les conducteurs de puissance (C1, C2) et un deuxième organe de mesure (O2) d'un courant circulant dans au moins un des conducteurs de puissance (C1, C2). Le dispositif comprend également un calculateur (UP) configuré pour déterminer, sur une période d’observation déterminée, une énergie mixte (Emix) transportée dans la zone de mesure à partir de la première grandeur (Vres) et de la deuxième grandeur (Inet). L’invention porte également sur un équipement, un système de localisation et un procédé de détection d’une défaillance dans un réseau électrique. Figure à publier avec l’abrégé : Fig. 1The invention relates to a device (D) for detecting a fault in an electrical network (1) comprising at least two pieces of electrical equipment (E) connected by at least a first power conductor (C1), a second power conductor (C2) and the electrical network (1) also comprising a common conductor (Cc). The device comprises a first member (O1) for measuring the common mode voltage present on the power conductors (C1, C2) and a second member (O2) for measuring a current flowing in at least one of the power conductors (C1, C2). The device also comprises a computer (UP) configured to determine, over a determined observation period, a mixed energy (Emix) transported in the measurement zone from the first quantity (Vres) and the second quantity (Inet) . The invention also relates to an equipment, a location system and a method for detecting a fault in an electrical network. Figure to be published with abstract: Fig. 1
