A voltage-dependent model for transformer core nonlinearity suitable for undergraduate instruction is proposed. The model is based on Fourier series representation of the excitation current, and its parameters are determined with the aid of computer software and measured data. Laboratory experiments are performed to determine the model and verify its validity. The experiment shed light on transformer nonlinearity when used as part of the classical experiment on transformer saturation in the undergraduate energy conversion/power systems laboratory course.
