Three-phase transformers are passive devices that transfer electrical energy between circuits. In the secondary circuit, the magnetic flux induces an electromagnetic force, increasing or decreasing the voltage without changing the frequency.

The three-phase transformer has a triple iron core on which the coils of the primary and secondary sides are placed in triple. The coils of the individual phases of the primary and secondary windings can be connected in different ways, allowing a large number of phase combinations, e.g.: YNyn0, Dd0, Dyn1, Yyn0, Yz0, Yy, Dy.
