摘要：

This paper describes the development of an electromagnetic transient model to represent the eddy current effects in transformer magnetising current. ne magnetising current of a transformer is both non-linear and frequency dependent. The frequency dependence is due to eddy currents. ne most commonly used method to represent losses in a transformer model is to add a shunt resistance across one winding. In this paper we have extended a hysteresis model based on the Jiles Atherton theory of ferromagnetic hysteresis to include the effects of eddy currents. A comparison of simulation results and test results is presented in the paper.
