energy efficient transformer

In a typical power distribution grid, electric transformer power loss typically contributes to about 40-50% of the total transmission and distribution loss. Energy efficient transformers are therefore an important means to reduce transmission and distribution loss.B. Kennedy, “Energy Efficient Transformers” McGraw-Hill, 1998. With the improvement of electrical steel (silicon steel) properties, the losses of a transformer in 2010 can be half that of a similar transformer in the 1970s.{{Citation needed|date=July 2010}} With new magnetic materials, it is possible to achieve even higher efficiency. The amorphous metal transformer is a modern example.{{Cite web |url=http://jerryli.110mb.com/Asian_Energy_2000.pdf |title=J.
