摘要：
Based on multi-conductor transmission lines (MTLs) theory, a new model of partial discharge pulse propagating in single phase transformer is established. The parameter matrices C in the model are calculated based on static-steady electromagnetic field theory, and other parameters R, L, G result from the relationship between the parameters. The transformation of mode voltages and mode currents is applied in order to obtain MTL general solution, and the transfer functions of transformer winding are obtained. then scattering parameter method for measuring the transfer characteristics of transformers winding are presented. The experimental results tested on 180-turn single winding and 400kV transformer winding consistent with the simulation results derived from their MTL model.
