                                         TransformerStarImpedance

Transformer star impedance (Pi-model) that accurately reflects impedance for transformers with 2 or 3 windings. For transformers with 4 or more windings, you must use TransformerTank model and related classes. For transmission networks use PowerTransformerEnd impedances (r, r0, x, x0, b, b0, g and g0).
