A polyphase transformer (101) comprises a number of toroidal cores (102) adjacently arranged in an axial direction. The toroidal cores (102) support phase windings of different phases. The connecting points of the phase windings of two adjacent toroidal cores (102) are offset from one another in a peripheral direction. This offset, i.e. of the geometric angles between the connecting points of the phase windings of two adjacent toroidal cores (102) approximately corresponds to the phase shift, i.e. to the electric phase angle between the voltage signals of these toroidal cores (102).

L'invention concerne un transformateur polyphasé (10) qui présente plusieurs noyaux toroïdaux (102) disposés de manière adjacente, dans le sens axial, les noyaux toroïdaux (102) portent à cet effet, des enroulements de phase de différentes phases. Les points de connexion des enroulements de phases de deux noyaux toroïdaux (102) adjacents sont disposés de manière décalée les uns par rapport aux autres dans le sens périphérique. Le décalage ou l'angle géométrique entre les points de connexion des enroulements de phase de deux noyaux toroïdaux (102) adjacents correspond approximativement au décalage de phase ou à l'angle de phase électrique entre les signaux de tension de ces noyaux toroïdaux (102).
