Изобретение относится к электроизмерительной технике и может быть использованы для измерения электрической энергии в цепях переменного тока в целях коммерческого учета. Предлагаемые способ и устройство (варианты) позволяют упростить измерение электрической энергии и повысить точность в нормальном режиме измерения при обеспечении защищенности его результата от вмешательства с целью хищения. Способ предполагает формирование суммарного сигнала из сигналов, пропорциональных, соответственно, разности и сумме токов фазного и нулевого проводов цепи нагрузки, формированию сигнала мощности из сигнала напряжения нагрузки и сигнала, характеризующего ток нагрузки, преобразование сигнала мощности нагрузки в сигнал тока или напряжение, преобразование его в частоту импульсного сигнала и последующий подсчет числа импульсов в качестве результата измерения. Новым в первом варианте предлагаемого способа является то, что суммарный сигнал, характеризующий ток нагрузки, формируется в виде суммы двух сигналов, один из которых пропорционален сумме, а другой разности токов фазного и нулевого проводов. Кроме того, преобразование в частоту импульсного сигнала предлагается выполнять независимым от направления мощности нагрузки. Отличием второго варианта способа является то, что в суммарном сигнале сигнал разности токов учитывают со знаком, соответствующим его направлению, которое определяют знаком соответствующей ему мощности.The invention relates to electrical engineering and can be used to measure electrical energy in AC circuits for commercial metering. The proposed method and device (variants) can simplify the measurement of electrical energy and improve the accuracy in the normal measurement mode while ensuring that its result is protected from interference with the purpose of theft. The method involves forming a total signal from signals proportional to, respectively, the difference and sum of phase and zero wires of the load circuit, generating a power signal from the load voltage signal and a signal characterizing the load current, converting the load power signal into a current signal or voltage, converting it into the frequency of the pulse signal and the subsequent counting of the number of pulses as a measurement result. New in the first variant of the proposed method is that the total signal characterizing the load current is formed as the sum of two signals, one of which is proportional to the sum and the other the difference of the phase and zero wires. In addition, the conversion to the frequency of the pulse signal is proposed to be independent of the direction of the power load. The difference of the second variant of the method is that in the total signal the signal of the difference of currents is taken into account with a sign corresponding to its direction, which is determined by the sign of the corresponding power.
