In the case of a three-phase transformer which, per phase (U, V, W), has a primary-side winding (U.sub.PW, V.sub.PW, W.sub.PW) and a secondary-side winding (U.sub.SW, V.sub.SW, W.sub.SW), in-phase regulating windings (U.sub.L, V.sub.L, W.sub.L) are provided on each limb per phase (U, V, W). These in
In the case of a three-phase transformer which, per phase (U, V, W), has a primary-side winding (U.sub.PW, V.sub.PW, W.sub.PW) and a secondary-side winding (U.sub.SW, V.sub.SW, W.sub.SW), in-phase regulating windings (U.sub.L, V.sub.L, W.sub.L) are provided on each limb per phase (U, V, W). These in-phase regulating windings (U.sub.L, V.sub.L, W.sub.L) serve, by means of a tap switch 3 and a load switch 6, for in-phase regulation for the purpose of reactive volt-amperes distribution in electrical power supply networks. In addition, the in-phase regulating windings (U.sub.L, V.sub.L, W.sub.L) are operatively connected via a further load switch 5 and a further tap switch 4 to a booster transformer (2). The voltages across primary windings U.sub.B, V.sub.B, W.sub.B of the booster transformer 2 effect quadrature or phase-angle regulation of the phase voltages U.sub.P, V.sub.P, W.sub.P in the three-phase transformer 1.
