Abstract

Système et procédé pour surveiller une connexion électrique et détecter une condition de défaillance de ladite connexion électrique définie par une valeur de résistance électrique supérieure à un seuil prédéterminé,le système électrique comprenant des moyens de détermination d’une température (TC) de la connexion électrique et des moyens de détermination d’un courant (IC) traversant la connexion électrique le procédé comprenant:- acquérir, au cours du temps, des valeurs successives de la température de la connexion électrique, et des valeurs successives de courant (IC),- calculer d’un apport d’effet Joule comme la moyenne de [IC(t)]²,- calculer un gradient temporel (GTC) de la température de la connexion, - calculer un gradient temporel relatif, défini comme le rapport du gradient temporel de la température de la connexion à l’apport d’effet Joule, et déclencher une alerte si le gradient temporel relatif est supérieur à une valeur seuil.
