Modelica.Magnetic.FluxTubes.Examples.Hysteresis.Components.Transformer1PhaseWithHysteresis

Single Phase transformer with ferromagnetic core and hysteresis

Information

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.

Three phase transformer in Yy configuration

Information

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.
