In the electric power equipments such as transformers and generators, magnetic shields are placed on the inner side of the tanks to prevent coil leakage fluxes from entering into the tanks. Some of the magnetic shields are constituted of laminated steels and ancillary steels which are welded to the laminated steels for the purpose of holding on the laminated states. In this paper, the eddy current losses of such magnetic shields are analyzed by using the homogenization method and the losses of the shields are measured by using the calorimeter measurement method. The effectiveness of the analysis is shown by comparing with the experiment.
