The objective of this work is to calculate stray losses in magnetic structures of 400 MVA 1-phase, 500–230 kV auto transformer and study the effect of copper shield on structural losses and winding eddy losses, using commercial software package Magnet (Infolytica Corp.) based on fi nite element method (FEM). The resulting eddy current losses may be considerable, thereby increasing the load loss of transformer. The stray fl ux intruding into the structural parts gives rise to eddy currents in them. The stray fi eld strength increases rapidly with growing rating. Yet these losses produce localized heating which can compromise its operation. The losses due to transformer leakage fi eld comprise a small percentage of the power in a transformer.
