Title (EN) APPARATUS AND METHOD FOR ARC FLASH PROTECTION IN ELECTRICAL POWER SYSTEMS
(FR) APPAREIL ET PROCÉDÉ DE PROTECTION CONTRE UN ÉCLAT D'ARC ÉLECTRIQUE DANS DES SYSTÈMES D'ALIMENTATION ÉLECTRIQUES
Abstract:
(EN) A circuit (30) for use in an electrical system (2) having at least one of a shorting device (14) or a first circuit interrupter (10) and having a second circuit interrupter (12). The circuit is configured to: receive a logical signal (26) indicative of an arcing event related to the electrical system; receive another logical signal (28) indicative of operation of the second circuit interrupter (12); and selectively operate or not operate the at least one of a shorting device or a first circuit interrupter dependent on at least one of the logical signals (26, 28).
(FR) L'invention concerne un circuit (30) destiné à être utilisé dans un système électrique (2) comprenant un dispositif de mise en court-circuit (14) et/ou un premier interrupteur de circuit (10) et ayant un second interrupteur de circuit (12). Le circuit est conçu pour : recevoir un signal logique (26) indiquant un événement d'arc associé au système électrique; recevoir un autre signal logique (28) indiquant le fonctionnement du second interrupteur de circuit (12); et faire fonctionner ou non de manière sélective le dispositif de mise en court-circuit et/ou un premier interrupteur de circuit en fonction d'au moins l'un des signaux logiques (26, 28).
