Calculation of Losses in the Core Clamps of a Transformer Using 3-D Finite-Element Method

The calculation of losses in the core clamps of a 40 MVA distribution transformer which occur due to winding stray field is presented. A principle of surface impedance has been used in a 3-D finite-element model of the transformer to calculate the losses. The influence of variations of the clamp dimensions and the material on the losses has also been analyzed.
