Medidor eletrônico de energia elétrica bidirecional não invasivo

Abstract

With the constant technological advancements, the daily necessity for electrical energy has been growing, thus, it has become important the development of technologies which allows the end user to monitor instant electrical values and even monthly consumption, allowing him, quickly and precisely, to keep up with details of his energy consumption. In view of that advancement, this work proposes the development of a non-invasive bidirectional electronic energy meter, allowing the user to monitor its energy consumption, demand and possible failures. For the project development it has been used the measuring integrated circuit MCP3909 responsible by capturing the electrical measurements, a microcontroller ATmega328 associated with the Arduino Nano board and a liquid crystal display. The meter design follows recommendations of integrated circuits and circuit boards manufacturers from Microchip, Analog Devices and Texas Instruments. In this work the meter prototype results obtained during the development, are going to be presented. All the considerations, methodology, calculations, final results as well as the possible improvements are described in its respective topics.
