Title (EN) METHOD AND SYSTEM FOR CHARACTERISING A FAULT IN A NETWORK OF TRANSMISSION LINES, BY TIME REVERSAL
(FR) PROCEDE ET SYSTEME DE CARACTERISATION D'UN DEFAUT DANS UN RESEAU DE LIGNES DE TRANSMISSION, PAR RETOURNEMENT TEMPOREL
Abstract:
(EN) The invention relates to a method for characterising a fault in a network of at least one transmission line, said method comprising the steps of: injecting (301) a first reference signal into the network; acquiring (302) a first measurement of the first reference signal after the propagation thereof into the network; temporally reversing (303) the measurement in order to generate a second reference signal; injecting (304) the second reference signal into the network; acquiring (305) a second measurement of the second reference signal after the propagation thereof into the network; and calculating (306) the intercorrelation between the second measurement and the second reference signal.
(FR) Procédé de caractérisation d'un défaut dans un réseau d'au moins une ligne de transmission, ledit procédé comprenant les étapes de : - Injecter (301) un premier signal de référence dans le réseau, - Acquérir (302) une première mesure du premier signal de référence après sa propagation dans le réseau, - Inverser temporellement (303) la mesure pour générer un second signal de référence, - Injecter (304) le second signal de référence dans le réseau, - Acquérir (305) une seconde mesure du second signal de référence après sa propagation dans le réseau, - Calculer (306) l'intercorrélation entre la seconde mesure et le second signal de référence.
