Information

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

Simple model of a single phase transformer with a primary and a secondary winding and a magnetic core. The core is modeled with GenericHystTellinenEverett flux tube elements. Thus, this element considers static and dynamic hysteresis.
