Title (EN) METHOD FOR DETECTING A SAG IN A PHASE VOLTAGE OF AN ELECTRICAL NETWORK
(FR) PROCEDE DE DETECTION D'UN AFFAISSEMENT D'UNE TENSION DE PHASE D'UN RESEAU ELECTRIQUE
Abstract:
(EN) Method for detecting a sag in a phase voltage (Vp) comprising the steps of: - measuring, upstream of a switching member and at regular intervals, the phase voltage (Vp) and a phase current (Ip) flowing through a phase conductor (13); - when the phase voltage falls below a predetermined voltage threshold, opening the switching member; - subsequent to opening the switching member, if the phase voltage returns to a normal voltage value defined according to the phase current (Ip), detecting a malfunction of the electricity meter, generating a warning message, and keeping the switching member open; - subsequent to opening the switching member, if the phase voltage remains below the predetermined voltage threshold, detecting a sag in the phase voltage (Vp), generating an alert message, and closing the switching member (12).
(FR) Procédé de détection d'un affaissement d'une tension de phase (Vp) comprenant les étapes : - de mesurer, en amont d'un organe de coupure et à intervalles réguliers, la tension de phase (Vp) et un courant de phase (Ip) circulant sur un conducteur de phase (13); - lorsque la tension de phase devient inférieure à un seuil de tension prédéterminé, d'ouvrir l'organe de coupure; - suite à l'ouverture de l'organe de coupure, si la tension de phase reprend une valeur de tension normale définie en fonction du courant de phase (Ip), de détecter un dysfonctionnement du compteur électrique, de générer un message d'alarme, et de maintenir ouvert l'organe de coupure; - suite à l'ouverture de l'organe de coupure, si la tension de phase demeure inférieure au seuil de tension prédéterminé, de détecter un affaissement de la tension de phase (Vp), de générer un message d'alerte, et de refermer l ' organe de coupure (12).
