Sistema embarcado aplicado a medição de energia elétrica de baixo custo

Abstract

With the development of the Brazilian electric sector, new tariff modalities have emerged, providing low-voltage consumers with new charging options and, in parallel, new technologies have been developing to help with the electrical consumption of installations and the same occurs when choosing the charging. Within this context, in this work, a survey of electrical energy measurement and analysis equipment on the market was carried out, and a low cost electrical energy measuring device was developed through the use of an embedded system. It is important to note that, for data validation, a test was carried out to compare it with market equipment. After the tests, the system demonstrated a behavior statistically similar to the measurement with the market equipment, validating the measurement for this type of technology. In relation to the equipment available on the market, it was observed that energy meters are vulnerable to the consumer as regards the safety of independent installation and the analyzers presented an associated cost that limit the use of the Group B consumer. Thus, this work corroborated with the reliability that embedded systems have in the energy measurement segment as well as demonstrated potential for future development in the energy sector.
