Ideal transformer (lossless) with a variable tap

Extends from BaseClasses.BaseTransformerVariableTap (Base class for ideal and classical transformers with variable tap), AdditionalIcons.Transformer.

Information

This model is an ideal transformer model with variable tap (that can be adjusted by an external other model such as the tap changer logic defined here). It means that the transformer is lossless and the current and voltages on both sides are linked by the following equations:

rTfoPu = U2/U1 and rTfoPu = - I1/I2 

The ideal transformer equivalent circuit is:


               I1   r  I2
    U1,P1,Q1 -->---oo---<-- U2,P2,Q2
  (terminal1)              (terminal2)
