Abstract

Circuit d'essai pour dispositif fonctionnant à l'aide de courant résiduel, comprenant un tranformateur de courant (24) par lequel passent les conducteurs de ligne et de neutre (12, 14) connectés entre une source de courant alternatif et une charge. Le circuit d'essai comprend un commutateur d'essai (96) et une résistance d'essai (98) agencés pour être couplés en série entre le conducteur de ligne et une ligne (44) de tension zéro ou de basse tension d'une alimentation en courant continu au moyen d'au moins deux spires d'un enroulement d'essai bifilaire ou double sur le transformateur de courant afin de produire un courant d'essai lors de la fermeture du commutateur de test.
