AC power meter design for home electrical appliances
Monitoring power consumption of portable appliances is a step towards energy saving plans for any electrical equipment. This paper proposes a customizable power meter design employing voltage and current transformers, and Arduino. This meter is to monitor RMS voltage and current, real and apparent power, and power factor in real time. The voltage, the current, and the real power are calibrated with respect to a reference power meter. The resolutions are derived from analytical approach and the accuracies are evaluated from experiments in a variable of appliances and current transformers.
