Estimador de potência aparente utilizando sensor de corrente para aplicaçâo residencial

Abstract

In the current context, where much cares about sustainability and renewable and non-renewable energy, the trend over time will optimize the way in which this energy will be used. This work aims to develop an instrument who estimate the apparent power of each individual residential or industrial device to monitor their consumption and return the user to the efficiency. From a current sensor together with an amplifier circuit and a microcontroller developed meter can measure the RMS current in this particular apparatus, may thus estimate its apparent power. With the measures, it is possible monitorate the consumption of active power loads purely components that do not exhibit delays on waveform of current.
