Abstract

The authors discuss the 3-D electromagnetic modeling of a transformer to evaluate eddy current losses in the tank. To achieve this, several numerical methods are used with two 3-D field computation packages. Conventional volume elements and shell elements are used for the modeling of thin conducting regions. Surface elements are used for the modeling of conducting regions with a reduced skin depth. The results, along with several characteristics of the tank and magnetic core, are compared. The influence of the characteristics of these two components is investigated
