摘要：

This paper discusses the processes of power loss development in the joint area of the laminated transformer core due to eddy currents produced by the normal magnetic flux. Normal magnetic flux is directed in perpendicular to the plane of the laminations and the dominating factor in the power loss formation in the joint area. The analytical approach was verified by a set of tests where two experimental setups have been employed to investigate power loss in the laminations under various conditions. The tests provided data on the power loss produced by the normal flux in relation to the lamination width and lamination overlap length. It was shown that the power loss in the joint area significantly depends on the lamination width and is independent of lamination overlap.
