The ultra efficient amorphous substation transformer

The author describes amorphous core transformer technology development and broadly compares the technical characteristics and performance to those of conventional high-efficiency silicon steel transformers. How amorphous transformer technology can reduce industrial power losses and improve productivity is addressed. It is pointed out that the ultraefficient amorphous metal core transformer technology offers the industry a conservation alternative which can help the energy equation and boost productivity. Amorphous core distribution transformers (10 kVA through 2500 kVA) have become a technological and commercial reality with potential for reducing US utility losses and stretching scarce generating capacity by over 7000 MW, equivalent to 60 billion kWh annually. Application of this advanced technology to liquid filled industrial substation transformers (10 kVA through 2500 kVA) will provide potential for additional conservation of over 2500 MW, equivalent to 22 billion kWh annually.<>
