Information

This information is part of the Modelica Standard Library maintained by the Modelica Association.

Partial model of a three-phase transformer, containing primary and secondary resistances and stray inductances, as well as the iron core. Circuit layout (vector group) of primary and secondary windings have to be defined.
Exactly the same as Interfaces.PartialBasicTransformer, included for compatibility reasons.
