Abstract: The stray losses in tank walls, yoke clamps, tensile plate of core
limb and other electrically conductive construction parts of a transformer are
computed using three-dimensional time harmonic finite element method. The
distributions of losses in the construction parts are then analyzed, and the
measures of controlling and reducing stray losses were discussed. The different
types of magnetic shields are investigated to reduce the eddy current loss in
the tank wall and the yoke clamps. Influence of both shielding types and
dimensional parameters of a specific shield on the stray losses is discussed to
fascinate engineering applications.
Keywords: Power transformers, stray losses, magnetic shields
