Low cost system for real-time monitoring of electrical parameters

摘要

This paper presents the design and implementation of a system to monitor the energy quality using ATmega2560 microcontroller embedded in the Arduino MEGA board. The proposed system is capable of acquiring voltage and current signals at sampling rate of up to 22 kHz simultaneously, and through digital processing obtains the basic parameters of the electrical signal. The samples obtained are possible to send, at various transmission rates, through the USB port to the computer. The components used in the realization are of low cost compared with the existing equipment at commercial level. The reliability of the system is validated by comparing the results with electrical metrology equipment.
