Numerical Investigation of the Effects of Temperature-Dependent Permittivity and Space-Charge Transport on the Electric-Field Distribution in the Oil–Paper Insulation of an Oil-Immersed Transformer

To investigate the effects of the thermal state under rated operation and space-charge transport on the electric-field distribution in oil–paper insulation, a sequentially coupled multiphysics model is developed for a 30 kVA single-phase three-limb oil-immersed transformer. The n...
