Abstract:Two approaches to 3-D magnetic field calculations for low-power special transformers are presented in the paper. The application of fast calculation procedures based on the finite difference method, to direct solving of the Poisson and Laplace equations is given. The calculated example deals with the three-phase leakage transformer. On the other hand, the iterative solution of regularized integral equations used for calculation of 3-D field distribution and integral parameters of leakage field in current transformer is also presented. The software packages developed by the authors are useful for computer-aided design of low-power special transformers.
