An efficient and precise finite network model to simulate the dynamic behaviour of transformer core laminations is presented. The model considers both hysteresis and eddy current losses and is based on an electric and magnetic circuit connected by a gyrator. This approach allows to easily include the classical Preisach operator to take into account hysteresis and saturation behaviour. The eddy current losses are modelled with an additional inductance in the magnetic circuit. Simulation results are in good agreement with measurements of a single phase and three phase transformer as used in power-supply systems.
