Abstract

The quest for cost reductions increases the demands on quantity each day and more on the quality of what is consumed. In particular in the evaluation of electric energy, its quality parameters besides being legal requirements, are decisive points in energy saving, which in the competitive market that is established can be a decisive parameter. Electrical equipment manufacturers are presenting better products that add more functions, with less volume and with a lower energy consumption. This has been achieved due to the evolution of microprocessor devices and power electronics that allow more precise and efficient control of electricity. However, the use of these technologies is correlated to nonlinear components, which generate different harmonics in the network, which increases the losses and decreases the quality of the electric system energy. Therefore a device for the analysis of the power quality is so important, being a crucial tool for the professional responsible in fix and / or designing a system. The general objective of this paper is to perform an analysis of the power quality of the Laboratório de Sistemas de Potência (LSP) located in Universidade Federal de Campina Grande (UFCG), based on the parameters required in the Procedimentos de Distribuição de Energia Elétrica do Sistema Elétrico Nacional or PRODIST, specifically in Module 8, By the Agência Nacional de Energia Elétrica (ANEEL). For the accomplishment of the activities a Nexus 1500+ energy quality analyzer was used, that is of own possession of the laboratory.
