Frequency effect on calculation for voltage distribution of winding

This paper models simplified transformer winding model by multi-conductor transmission line (MTL) model. Because inductance and resistance of transformer winding are frequency-dependent parameters, frequency effect on parameters should be considered when calculating distributed parameter matrices. Then, when solving for voltage distribution of winding model, the distributed parameter matrices should be selected according to the frequency of signal source. Because of frequency change, voltage distribution of winding model changes very significantly. This phenomenon can be verified by accurate experiment.
