An efficient method is presented for calculating the response of transformer windings under VFTO based on network function in this paper. Firstly
the voltage transfer functions are calculated from the scattering parameters of each section which is measured by network analyzer. Secondly
the voltage transfer functions are fitted with rational functions by vector fitting codes. Finally
the voltage responses of each section are calculated via recursive convolution using the pulse response and the input signal. They are compared with the measured voltage responses in time domain. The calculated voltages are in agreement with the measured voltages. It shows that the method is simple and correct.
