Abstract

During the development of technical devices, numerical simulations are widely used to avoid costly experiments. Here, the insulation properties of a single-phase transformer are calculated using a discretization scheme which accounts for cylindrically symmetric parts by local sub-grids. The size of the numerical model is therefore reduced significantly while a high accuracy is maintained. For the optimal insulation configuration the field intensity is decreased significantly.
