Abstract

The aim of the present paper is to describe a computational tool designed to analyze voltage unbalance. This tool was developed with the MATLAB programming language and utilizes measurements from a variety of instruments for the purpose of creating databases which may then be characterized, analyzed and interpreted in accordance with several different standards and electrical recommendations. As a result, this article initially presents the definition of voltage unbalance, some basic considerations on its causes and effects, its main calculating methods and finally a brief overview of the main standards involved. From this point a software program is proposed to analyze the mentioned parameters. The relevance of this tool resides in its ability to assist electrical companies, universities, and those professionals interested in quantifying and classifying voltage unbalances
