Amorphous metal transformer

Amorphous metal transformer

Amorphous Metal Transformer (AMT) is a type of energy efficient transformer found on electric grids. [B. Kennedy, “Energy Efficient Transformers” McGraw-Hill, 1998.] The magnetic core of this transformer is made with amorphous metal, which is easily magnetized / demagnetized. Typically, core loss can be 70–80% less than its traditional counterpart. This leads to a reduction of generation requirement and less CO2 emission. [J.Li, “Climate Change and Energy—Opportunities in China”, presented in "Climate Change: The Business Forecast" Conference", London, Oct 2005. (Available from links on Jerry Li 's page at] [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] It has been widely adopted by large developing countries such as China [“SPC Note on T&D network loss reduction and energy saving plan” SPC Transportation and Energy Section, Document #123, 1997 (in Chinese).] and India [B.S.K. Naidu, “Amorphous Metal Transformers—New Technology Developments”, Keynote Speech, CBIP-AlliedSignal Seminar (India), April 1999.] where energy conservation and CO2 emission reduction have been put on priority. These two countries can potentially save 25–30 TWh electricity annually, elimate 6-8 GW generation investment, and reduce 20–30 million tons of CO2 emission by fully utilizing this technology.
