Information
This information is part of the Modelica Standard Library maintained by the Modelica Association.
Simple model of a three-phase transformer with primary and a secondary windings and a magnetic E-I shaped core. The core is modeled with GenericHystTellinenEverett flux tube elements. Thus, this model considers static and dynamic hysteresis as well as initial flux.
