Estudo de caso sobre o impacto da correção do fator de potência em uma indústria do Polo Industrial de Manaus

Abstract

The industrial sector is one of the main consumers of electrical energy in Brazil, representing a significant portion of companies’ operational expenses. One of the factors that directly influence these costs is the power factor, whose low efficiency can result in financial penalties imposed by electric utilities. This paper presents a case study on power factor correction in an industry located in the Manaus Industrial Pole, using data obtained from an outsourced company responsible for the plant’s electrical monitoring. After assessing the losses caused by reactive energy through the analysis of previous years’ electricity bills, the study aims to identify the power factor behavior in the facility’s transformers and propose technical and economic alternatives for its correction, based on the use of fixed and automatic capacitor banks. The study is expected to demonstrate the economic impact of power factor correction and its benefits in terms of energy efficiency and operational cost reduction.
