The ultra efficient amorphous substation transformer

A brief description is given of amorphous transformer technology development, and a comparison is made of the technical characteristics and performance to conventional high-efficiency silicon steel transformers. The author addresses how amorphous transformer technology can reduce industrial power losses and improve productivity. It is shown that amorphous transformers have a role in the equation of industrial productivity improvement. Each industrial user must make an independent assessment. Some will derive greater benefits than others. Most will realize some benefits. Benefits are considered to be greatest in the following situations: (1) areas with high electricity costs; (2) when transformer replacement is happening for PCB removal or other reasons; (3) when a plant is being constructed; (4) where transformers are inside and create an added air-conditioning load; (5) where transformers experience seasonal loads or extended low duty cycle; and (6) when overall economics justify replacing existing transformers for efficiency, reliability, or other reasons
