Abstract

This paper presents results for the economical analysis of efficient monophase transformers when used instead of standard transformers made at the High Voltage Laboratory if Federal University of Itajubá (LAT-EFEI). The analysis was made using capitalization rules based into two wages cycles, as recommended by Brazilian Electrical Energy Agency - ANEEL. In addition, it is also discussed, briefly, a comparison made with the traditional method using the present value of transformer losses costs. Finally, authors propose a methodology to study the application of efficient transformers to replace the ones standardized by Brazilian normative association, ABNT.
