An amorphous metal transformer (AMT) is a type of energy efficient transformer found on electric grids.[1] The magnetic core of this transformer is made with an ferromagnetic amorphous metal (e.g. Metglas), containing elements such as iron and glass former such as of boron, silicon, or phosphorus. These materials have high magnetic susceptibility, with low coercivity and high electrical resistance. The high resistance leads to low losses by eddy currents when subjected to alternating magnetic fields, a property particularly useful in transformers. Typically, core loss can be 70–80% less than with traditional crystalline materials. This leads to a reduction of generation requirement and, when using electric power generated from fossil fuels, less [[greenhouse gas|CO2 emissions It has been widely adopted by large developing countries such as China[2] and India[3] where energy conservation and CO2 emission reduction have been put on priority. These two countries can potentially save 25–30 TWh electricity annually, eliminate 6-8 GW generation investment, and reduce 20–30 million tons of CO2 emission by fully utilizing this technology.
As one of the major programs to improve grid efficiency, China has started to install amorphous metal transformers in a number of energy intensive provinces since 2005. Over 20,000 MVA of such transformers are installed every year. This movement has also led to the successful development and production of amorphous metal ribbon in China.[4]
