A Three Windings Power Transformer.

The equivalent star model used is:

Usually side 1 is the primary (high voltage), side 2 is the secondary (medium voltage) and side 3 the tertiary voltage (low voltage).

g1, g2, g3 and b1, b2, b3 unit is siemens.

r1, r2, r3, x1, x2 and x3 unit is ohm.

A Three Windings Transformer is connected to three voltage levels (side 1, side 2 and side 3) that belong to the same substation. It has three identical legs. Each leg has the same model of a Two Windings Power Transformer.

All three legs may have a Ratio Tap Changer and a Phase Tap Changer. A warning is emitted if a leg has both Ratio and Phase Tap Changers.

Only one Tap Changer is allowed to be regulating on the equipment. An exception is thrown if two or more regulating controls are enabled.

To create a three windings transformer, see ThreeWindingsTransformerAdder
