Abstract
This paper uses multi-conductor transmission line (MTL) to model transformer winding. According to capacitance, inductance and resistance parameter, transmission line equation can be solved by input terminal impedance method. Thus, voltage distribution in transformer winding can be obtained by solving MTL equation. In this paper, only voltage distribution at single frequency excitation is calculated. Then, the calculated voltage distribution is compared with the experimental result. Because PD signal can be separated into superposition of cosine wave by fast Fourier transform(FFT), research on single frequency voltage distribution has important significance on solving voltage distribution of PD signal.
