Shielding measures of power transformer to mitigate stray loss and hot spot through coupled 3D FEA

Leakage flux generated in the power transformers cause stray losses in metallic parts of the transformer. Stray losses largely affect the transformer hot spot which leads to thermal failure. It is necessary to mitigate the impact of leakage flux on metallic parts by employing magnetic shunts and edd...
