Title (EN) FAULTED CURRENT INDICATOR WITH PROTECTION AGAINST TEMPORARY OVERLOADS AND TRANSIENTS
(FR) INDICATEUR DE COURANT DE DEFAUT COMPRENANT UNE PROTECTION CONTRE LES SURCHARGES ET LES COURANTS TRANSITOIRES TEMPORAIRES
Abstract:
(EN) The disclosed faulted current indicator ignores temporary overloads and transients by inhibiting any trip resulting from an overcurrent signal until a disabling circuit senses that a fuse or circuit breaker has reduced the line current to zero.
(FR) L'indicateur de courant de défaut (ICD) présenté ici supprime les surcharges et les courants transitoires temporaires en bloquant toute interruption résultant d'un signal de courant de surcharge jusqu'à ce qu'un circuit de mise hors service détecte qu'un disjoncteur ou qu'un coupe-circuit a réduit le courant du secteur jusqu'à zéro.
