O PAPEL DO ENGENHEIRO ELETRICISTA COMO CONSULTOR EM QUALIDADE DE ENERGIA E EFICIÊNCIA ENERGÉTICA: um estudo de caso

Abstract

The presente paper aims to demonstrate the role of electrical engineer as a professional analyst in electrical power system quality and energy efficiency. Through the study of historical contextualization of the use of electrical energy in Brazil, it will demonstrate all the theoretical foundations on the parameters of power system quality analysis and electromagnetic phenomena caused by disturbances, as well as statistical tools that ensure the reliability of all the collected data, which are important when producing reports and diagnosis based on study of the indicators. Based on the theoretical elements discussed, a case study is realized in a company that works as a internal combustion engines rectifier located in Varginha, where disturbance in power quality is identified. Data is collected and all the statistical treatment and indicators interpretation are realized, allowing the proposal of implementation of a device that solves the power quality issue, related to the value of power factor. This way, the main objective is achieved, evidencing the importance of the profession of Electrical Engineering, and its fundamental contribution to the development of societies.
