Abstract

The efficiency of the finite element method (FEM) for the design and improvement of electromagnetic devices has already been established several decades ago. This powerful tool is also used for the improvement of power transformer designs whose complexity can be handled by the FEM. This paper addresses the influence of simplifications to be made on the geometries of power transformers for the performance of electromagnetic and thermodynamic simulations to diminish the computational time and to obtain the electric and magnetic fields, temperatures, and heat flow in the interior of the transformer.
