Abstract
The three dimensional finite element analysis of eddy current problems using the complex magnetic vector potential is applied to a practical three phase power transformer. The eddy current densities in the oil tank and other steel structure parts and the magnetic flux densities in the whole transformer are computed. Several methods to reduce the amount of computation are presented. The eddy current losses in steel materials are computed by combining numerical method with analytical. The computed results are in substantial agreement with the corresponding experimental values.
