Abstract

In this manuscript, a low-cost power transducer, suitable for the implementation of electrical power meter, is presented. The current sensing unit is based on a Rogowski coil, while the voltage transduction is performed with an active voltage divider. An analog multiplier is adopted to generate the instantaneous power waveform. Active power and apparent power are measured with a digital multimeter. Each element of the proposed transducer has been experimentally characterized by means of reference instrumentation, and the results reported and discussed.
