FIELD: electrical engineering.
SUBSTANCE: invention relates to electrical engineering and can be used in transformers and reactors with magnetic core of power systems. There is a three-phase magnetic conductor (1, 2, 3), on which network windings (4, 5, 6) are placed connected to each other in a star and in two phases of magnetic conductor (1, 3) there are compensating windings (7, 8) connected between opposite to each other.
EFFECT: new, leading to simplification, is that the terminals of the circuit of these windings 7, 8 are connected to the outputs of winding 5 of the third phase.
