Abstract:

A36 structural steel is used in shipbuilding industry, pipes that transport gas and oil, offshore structures, other type of structures, as well as in electric equipment especially in the structural parts of power transformers such as tank walls, flitch plates, and frames. Its use in these applications has focused the research on the mechanical properties. Hence, this paper is aimed on the magnetic properties. The analysis is carried out for three different ranges of operating temperature. Using the experimental Epstein frame method, the behavior of magnetization and the specific losses curves are obtained. Moreover, with the data obtained and using the finite element method, the model of the zone where high current bushings are mounted on a transformer is obtained and the eddy current losses in the tank wall are calculated.
