Development and Implementation of a Voltage Real-Time Monitor System of Electrical Network with Remote Access

Abstract

Abstract.This paper discusses the development and implementation of a digital power quality meter to comply with the new standard which will regulate the Power Quality in Brazil. Its main objective has been to become a low cost device capable of monitoring the main Power Quality indices of the new standard, such as the steady state RMS voltage, harmonic distortion, voltage fluctuation, voltage unbalance, voltage sags and swells, as well as power supply interruptions in real-time. Through a cellular GPRS module, the meter can be remotely controlled and configured. In this way, it can exchange measurements and information data with a remote server, thus constituting a Power Quality monitoring system.
