Three-phase transformers with wye primary and wye secondary windings
Description
Connections
Parameters
Modelica Standard Library
The Wye-Wye (or Yy) components are three-phase transformers with wye primary and wye secondary windings.
The base name of each component is Yyij, where ij are two digits that specify the phase shift between the primary and secondary windings. The numbers range from 0 to 12 and correspond to the hours on the face of a clock. For example, 02 corresponds to a phase shift of 60 degrees.
