Information
This information is part of the Modelica Standard Library maintained by the Modelica Association.
This simple model of an single-phase transformer shows the inrush currents due to the remanence of the core material (M330-50A). For an accurate modelling of the core material the GenericHystTellinenTable hysteresis flux tube element is used. The initial magnetization MagRel of the Core component is set to 80%. Simulation settings:
- Stop time: 0.02 s
- Number of intervals: 5000
- Tolerance: 1e-6
Then plot the flux density of the Core Core.B over the magnetic field strength Core.H and additionally the time course of the primary and secondary current and e.g. the power consumption of the iron core Core.LossPower (see the following figures).
