Abstract

Article presents effects caused by electromagnetic forces on the transformer windings. It shows dimensions, direction and of course caused mechanical stress. Equation shows basic dependencies of these mechanical forces created in the transformer windings. The last part of the article is focused to the simulation method which shows the mechanical stress caused by the short circuit-currents. This method is preferred for analysis of power transformer.
