Amorphous Metal Transformer (AMT) is a kind of energy efficient transformer found on electric grids [1]. The magnetic core of such transformer is made with amorphous metal, which can be easily magnetized / demagnetized. Because of this property, core loss of AMT is significantly lower than conventional transformer. Typically, core loss can be reduced by 70-80% as compared to its traditional counterpart. Reduction in energy loss leads to reduction of generation requirement and hence less CO2 emission. As energy shortage and environmental concerns are increasingly recognized, this technology has also caught attention [2][3]. In particular, it has been widely adopted by big developing countries such as China [4] and India [5] where energy conservation and CO2 emission reduction have been put on priority. These two countries, for example, can potentially, on annual base, save 25-30TWh electricity, elimate 6-8GW generation investment, and reduce 20-30 million tons of CO2 emission by fully utilizing this technology.
