Amorphous metal transformer
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 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, when using electric power generated from fossilized fuels, less CO2 emission.[2][3] It has been widely adopted by large developing countries such as China[4] and India[5] 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 (also see Ultra High Voltage (UHV) Transmission in China), China has started to massively install amorphous metal transformers in a number of energy intensive provinces since 2005. Over 20,000 MVA of such transformers are installed every year.[6][7] This movement has also led to the successful development and production of amorphous metal ribbon in China.[8]
