Abstract

Le dispositif de mesure de courant à isolement électrique comporte une entrée de signal connectée à un shunt (40) électrique, une sortie de signal de sortie (SO), et des moyens de transfert de signal à isolement électrique recevant le signal d'entrée et fournissant ledit signal de sortie. Les moyens de transfert comportent au moins un transformateur (14) de signal ayant au moins un enroulement (15) primaire pour recevoir un signal primaire (SP) représentatif dudit signal d'entrée, des moyens (16) de commutation pour découper le signal d'entrée et le fournir audit enroulement primaire, et des moyens (17) de commande des moyens de commutation électriquement isolés et comportant une entrée de commande recevant des signaux de commande (SC) pendant des périodes (TC) de commutation. Un déclencheur et un disjoncteur électrique comporte un tel un dispositif de mesure de courant et une unité de traitement de fonctions de protection électrique.
