Cassava flour (Manihot esculenta Crantz) is produced in different regions of Brazil and is part of Brazilian eating habit. The product is characterized by having energy value, containing fiber and carbohydrates. However, the cassava flour houses have generated negative impacts on the environment by burning firewood. Solar energy can be an alternative free, clean and rewable energy source. This paper...
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,...
This paper presents a study on gains with relocation of medium voltage monophase transformers, based on load profile data measured for 69 transformers belonging to the electrical rural network of a Brazilian utility — AES Sul. The main purposes of this analysis are the verification of possible benefits to the distribution network and reduction of total loss by relocation of the transformers. The study...
This paper presents a study aiming the project of efficient monophase distribution transformers to be used in regions of low energy demand. In these regions, due to the clients profile, no load losses are more expressive than losses in copper. The study necessary for the realization of this work was based on a survey accomplished by AES Sul — Distribuidora Gaúcha de Energia in partnership with the...
