“…The time interval Δt depends upon the sampling frequency. As the compensation method operates on the instantaneous values, (13) proves that, the sample contains information not only related with the amplitude but also related with the phase angle [20,21]. Therefore, the proposed algorithm not only provides the compensation of the amplitude but also provides the compensation for the phase angle of the measurement CT.…”

“…In the design of power monitoring systems and energy meters, the current sensing technology methods have been addressed for the use of shunt techniques, commercial current transformer-based probes, or Rogowski coils [ 20 , 21 , 22 ]. Magnetoresistive (MR) sensors offer an interesting alternative in applications where power processing requirements need compact and simple solutions.…”

In the present work, the design and microfabrication of a tunneling magnetoresistance (TMR) electrical current sensor is presented. After its physical and electrical characterization, a wattmeter is developed to determine the active power delivered to a load from the AC 50/60 Hz mains line. Experimental results are shown up to 1000 W of power load. A relative uncertainty of less than 1.5% with resistive load and less than 1% with capacitive load was obtained. The described application is an example of how TMR sensing technology can play a relevant role in the management and control of electrical energy.

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.
