Title
(EN) FAULT INTERRUPTING DEVICES AND CONTROL METHODS THEREFOR
(FR) DISPOSITIFS D'INTERRUPTION DE PANNES ET PROCÉDÉS DE COMMANDE DE CES DERNIERS
Abstract
(EN)
Fault interrupting devices and methods for controlling the same are disclosed. The fault interrupting devices may include a switch (22) on an electrical power line (24) and a controller (26) configured to operate the switch. The methods for controlling fault interrupting devices may include gathering data, determining from the data that a fault has occurred, opening the fault interrupting device to interrupt the fault, analyzing the data, and determining whether the fault interrupting device can be reclosed based at least partially on the analysis of the data.
(FR)
L'invention concerne des dispositifs d'interruption de pannes ainsi que des procédés de commande de ces derniers. Les dispositifs d'interruption de pannes peuvent comprendre un commutateur (22) sur une ligne d'alimentation électrique (24), et une unité de commande (26) conçue pour actionner le commutateur. Les procédés de commande des dispositifs d'interruption de pannes peuvent consister à recueillir des données, à déterminer à partir des données qu'une panne s'est produite, à ouvrir le dispositif d'interruption de panne afin d'interrompre la panne, à analyser les données, et à déterminer si le dispositif d'interruption de panne peut être refermé au moins partiellement en fonction de l'analyse des données.
