Abstract

Field experience verifies that even when good insulation coordination studies and well-accepted insulation design practices are applied, power transformers suffer dielectric failure as reported in the literature. The analysis of the failures and prevention of transformer require comprehensive knowledge of the transient voltages distribution in transformer winding. So this paper constructs a transformer circuit model to calculate transient voltage distribution along the transformer winding, which is based on a multiconductor transmission line (MTL) model. The simulated transient voltage distribution of axial series capacitance and shunt capacitance to ground is analyzed and proved out in the paper, which are in accord with the existing conclusion.
