ABSTRACT:
An electronic watt-hour meter comprising an electronic power measuring circuit generating pulses at a rate proportional to the power to be measured and an N-digit decimal counter device formed of non-volatile semiconductor elements. The pulses from the power measuring circuit are supplied to the lowest digit position counter of the N-digit decimal counter device and the two lowest digit position counters act as a frequency divider. The outputs of the consecutive and higher digit position counters than the lowest digit position counters are applied to corresponding display sections of a display device, respectively.
