This is a model of a three-phase transformer and rectifier unit using the Transformer3PhaseYyWithHysteresis model. Use the following simulation settings:
- Stop time: 0.2 s
- Number of intervals: 5000
- Tolerance: 1e-6
An example simulation shows the transformer inrush currents due to an initially magnetized transformer core.
Fig. 1: Transformer inrush currents due to initial magnetization of the magnetic core; (a) transformer primary currents; (b) transformer secondary currents; (c) flux densities of the transformer legs; (d) B(H) hysteresis loops of transformer leg one.; (e) instantaneous static hysteresis, eddy current and copper losses of the transformer; (f) approximated average static hysteresis, eddy current and copper losses of the transformer
