Abstract

Dispositif de transformateur de courant électrique notamment destiné à être raccordé à l'enroulement secondaire d'un transformateur monté en série sur un courant inducteur. Il comporte au moins un transformateur à noyau torique RW avec un corps conducteur LK traversant ledit noyau annulaire RK et jouant le rôle d'enroulement primaire, dont les deux parties d'extrémité KE1 , KE2 constituent les éléments de contact d'un dispositif de connexion à enfichage ST.An electric current transformer device in particular intended to be connected to the secondary winding of a transformer mounted in series on an inductor current. It comprises at least one toroidal core transformer RW with a conductive body LK passing through said annular core RK and playing the role of primary winding, of which the two end parts KE1, KE2 constitute the contact elements of a connection device plug-in ST.
