Analysis on the Shielding Effect of the Power Transformer Tank
The MV/LV transformer without a tank in the underground substation can produce remarkable interference with the computer Cathode-Ray Tube (CRT) displayers above the ground, because of the generated power frequency magnetic field. To resolve such problem, a tank with high conductivity or/and high permeability is needed to enclose the transformer. To evaluate the shielding effectiveness, the finite element method is adopted to calculate the leakage magnetic field outside the transformer tank with different materials. The calculated results show that the steel tank is able to achieve an enormous shielding effectiveness.
