Abstract Scope |
The US DOE minimum efficiency levels for distribution transformers have evolved over the past decades and currently the most recent 2016 standard is being considered for revisions. This talk focuses on some key points of review in the standard. The distribution transformer market continues to be the largest market for Fe-based amorphous ribbon and has been shifting towards higher induction levels (1.63T) with increased stacking factor (>90%). New grades of amorphous transformer cores with lower losses and improved designs are currently being introduced. Amorphous based transformers have always had an advantage when using a total ownership cost evaluation. However, the improvements in today’s amorphous ribbon and the increase in efficiency standards make amorphous transformers favorable in many first cost designs as well. |
