Abstract

La présente invention a trait à un agencement permettant de réduire le couplage capacitif, qui comprend des enroulements auxiliaires (112, 113, 114) dans un espace situé entre un enroulement (110) et une autre partie (111) d'un dispositif électrique. L'enroulement et l'autre partie peuvent être, par exemple, des enroulements primaires et secondaires d'un transformateur. Une première extrémité de chaque enroulement auxiliaire est couplée à un potentiel électrique fixe par l'intermédiaire d'un élément électrique. Dans la direction (126) d'un axe magnétique de l'enroulement, au moins un des enroulements auxiliaires est plus court que la longueur d'un système d'enroulement auxiliaire constitué des enroulements auxiliaires. Le plus court enroulement auxiliaire constitue un blindage capacitif qui réduit le couplage capacitif entre l'enroulement et l'autre partie sans présenter de tension induite élevée qui serait à son tour couplée de façon capacitive.
