modelTransformer3PhaseYyWithHysteresis
Three-phase transformer in Yy configuration
Extends from Interfaces.ConditionalHeatPort (Partial model to include a conditional HeatPort in order to describe the power loss via a thermal network).
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.
