Abstract

The transformer has respective primary and secondary windings (Upw,Vpw,Wpw),( Usw,Vsw,Wsw) for each phase, and a longitudinal regulating winding (Ul,Vl,Wl). There are two transverse regulating windings (Uq1,Vq1,Wq1),(Uq2,Vq2,Wq2) for each phase, cooperating with the primary and/or secondary windings. The longitudinal and transverse regulating windings are each provided by partial windings, in which each longitudinal regulating winding cooperates with the primary and/or secondary windings for the same phase. Each transverse regulating winding cooperates with the primary and/or secondary winding for a different phase.
