Energy efficient transformer

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 [ B. Kennedy, “Energy Efficient Transformers” McGraw-Hill, 1998. ] . 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 [J. Li, “Use of Energy Efficient Transformers in Asia”, presented in "Asian Energy Conference 2000", Hong Kong. (Available from links on Jerry Li 's page at http://www.jerryli.co.nr)] .
