Abstract

Transformateur de conversion d'une connexion en etoile en une connexion en 2-delta pour un equipement electrique. Les transformateurs conventionnels ont ete fabriques jusqu'a present en une seule unite. Dans ce transformateur, des tensions differentes peuvent etre reproduites en connectant le cote secondaire du transformateur en deux connexions au travers du meme circuit magnetique. Cette connexion est fabriquee de maniere a la convertir en la connexion adaptee au besoin de l'utilisation, ce qui permet d'obtenir un systeme optimal de facilite electrique avec un transformateur qui est en meme temps efficace quant a la consommation d'energie et peu couteux a la fabrication.
