Abstract :
A new electronic method for electric energy measurement is described. The suggested method makes possible the construction of watthour meters without directly employing an electronic multiplier. The method is based on the utilization of a V/F converter with an inverse F/V conversion in the feedback loop. The input voltage and current signals modulate the basic frequency in such a way as to produce, in a given time interval, a number of pulses proportional to the energy present during the interval. The principal advantage of the system is the significant component reduction, enabling the construction of domestic watthour meters compatible in cost with the Ferraris type solutions.
