Energy efficient transformer

In a typical grid, electric transformer loss typically contributes about 40-50% of the total transmission & distribution loss. 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. The amorphous metal transformer is a modern example[2].
