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.
