Abstract

L’invention concerne un dispositif (1) de mesure de courant comportant une première (2) et une deuxième (5) unités de mesure de courant distinctes, chacune configurée pour mesurer le courant dans un circuit électrique (3) et envoyer des premier (4) et deuxième (8) signaux de mesure représentatifs du courant mesuré. Il comporte une unité de test (9, 10) pour générer et envoyer un signal de référence (11, 12), comportant une unité de contrôle (13) comportant un premier mode de fonctionnement dans lequel l’unité de contrôle (13) reçoit un signal de référence (11, 12) en provenance d’une unité de test (9, 10) pour détecter un défaut de l’unité de contrôle (13) et un deuxième mode de fonctionnement dans lequel l’unité de contrôle (13) reçoit les premier (4) et deuxième (8) signaux de mesure pour évaluer le courant et détecter un défaut par comparaison de signaux de mesure.
