A software package based on the finite element technique has been developed to compute two dimensional magnetic field and loss distribution in transformer cores with the aid of a 386 microprocessor based personal computer. The finite element method offers a stable numerical solution with a high degree of precision and the software package takes into account both the non-linear B-H characteristic and the anisotropy of the core material. Optimum design of transformer cores is reasonably fast and cheap with this software in comparison with FEM packages run on mini or main frame computers. This paper describes several important features in developing the software package and shows computed results for various three-phase three-limb transformer cores.
