Two Winding Transformer¶
Model of a two winding transformer. It is assumed, that node A is the node with higher voltage.
Attributes, Units and Remarks¶
Type Model¶
All impedances and admittances are given with respect to the higher voltage side. As obvious, the parameter can be used in T- as in 𝜋-equivalent circuit representations.
