The optimal ratio of the number of turns of the semi-phases of the secondary windings of a transformer with a zigzag circuit with zero

Voltage asymmetry occurs in 0.38 kV networks as a result of phase load asymmetry. This is accompanied by a negative impact on the operation of lighting and power receivers. Phase voltage asymmetry can be eliminated by using schematic solutions. First of all, the use of "star - zigzag" connection schemes with zero in consumer transformers. To do this, it is necessary to determine the optimal ratio of the number of turns of the semi-phases of the secondary windings of the transformer.
