Applying Improved Efficiency Transformers

Abstract

Today's business and energy conscious environment affords both producers and consumers of electric energy an opportunity to reduce costs and conserve energy through the use of improved efficiency transformers. Various design techniques that manufacturers utilize to reduce transformer losses are presented. Investment guidelines are provided for performing an economic evaluation and determining if an improved efficiency transformer can be justified. The decision to spend additional capital dollars for reducing transformer losses is based on the evaluation meeting or exceeding a specified internal rate of return (IRR). Proposals for selection and application of improved efficiency transformers are presented as part of the overall summary and recommendations.
