FIELD: electricity.
SUBSTANCE: invention relates to electric engineering. The invention claims a three-phase balancing device where a three-phase three-leg transformer contains windings connected in an opposite staggered way. Free leads of the first windings are connected to output terminals and free leads of the second windings are connected into a common zero point to couple phase loads. In each phase there is one or two in-series voltage adding windings coupled through a two- or three-position switch in sequence with load at the side of the supply mains.
EFFECT: provision of the phase voltage balancing.
