Prototype Development Open Source Platform-Based Electricity Meter with Minimum Rate of Change According to Module Five of the Electricity Distribution Procedure in the Brazilian National Electrical System (PRODIST)

Abstract

The article proposes the development of a low-cost, well-performing open source residential energy consumption demand meter compared to commercial meters in order to achieve accurate results and remain within the limits determined by technical standards, with the objective of measuring real and instant energy consumption through microcontroller and current sensor. The prototype has the ability to provide energy consumption data for a low voltage residential load or wiring to obtain the final amount of energy consumption Data is collected in stages by collecting current and voltage,  the microcontroller receives analog stimuli from sensors, as voltage and current samples are processed to calculate power, current and voltage. The use of the device leads the consumer to clarify the instantaneous energy consumption per installed component and it is possible to compare the cost benefit in relation to the energy consumption, providing consumers the follow up and a detailed view of its consumption, leading to efficient and sustainable use, enabling the improvement of the quality of energy supply to equipment connected to the distribution system.
