%X This research introduces the study carried out on one of Baghdad East 132/33/11(6.6) kV distribution substations to mitigate 50Hz magnetic field of indoor distribution substation under normal operation. Shielding was performed at the power sources such as busbars rather than at the affected areas. Three-dimensional finite element method (FEM) is used to calculate the magnetic field density in the space nearby the busbars so as to analyze the shielding effectiveness of an eddy current shield applied to a 132/33/11(6.6)kV substation. It also deals with the influence of shield distance from busbar, thickness and material of shield on the eddy current losses and shielding efficiency applied to 3D finite element model of a particular busbar configuration.
