In a typical grid, electric transformer loss typically contributes about 40-50% of the total transmission & distribution loss. A transformer is a device that transfers Electrical energy from one circuit to another through inductively coupled Electrical conductors Energy efficient transformer is therefore an important mean to reduce T&D loss[1]. With the improvement of electric steel (silicon steel) properties, loss of a transformer today is reduced to half of that of the transformer in the 70's. With new magnetic materials, it is possible to achieve even higher efficiency. Amorphous metal transformer is a modern example[2]. Amorphous Metal Transformer (AMT is a type of Energy efficient transformer found on electric grids
