Three-phase transformers with delta primary and zigzag secondary windings

Modelica Standard Library

	Description
	The Delta-Zigzag (or Dz) components are three-phase transformers with delta primary and zigzag secondary windings. The base name of each component is Dzij, 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.
