Устройство относится к электроизмерительной технике и позволяет повысить точность измерения расхода активной электроэнергии путем запрета счета импульсов при токах, меньших по величине значения, соответствующего допустимой погрешности. Измерение расхода электроэнергии осуществляется путем умножения сигналов, пропорциональных напряжению и току, с помощью множительного элемента, преобразования произведения в частоту следования импульсов в частотно-импульсном преобразователе и суммировании этих импульсов в отсчетном устройстве. Поступление импульсов на вход отсчетного устройства через элемент И возможно только при включенном состоянии порогового элемента, которое соответствует действию на его входе сигнала с выхода преобразователя активной составляющей тока, превышающего заданный уровень.The device relates to electrical measuring equipment and allows to increase the accuracy of measuring the consumption of active electricity by prohibiting the counting of pulses at currents lower than the value corresponding to the permissible error. Energy consumption is measured by multiplying signals proportional to voltage and current using a multiplier, converting the product to the pulse frequency in a pulse frequency converter and summing these pulses in a reading device. The arrival of pulses at the input of the reading device through the element AND is possible only when the threshold element, which corresponds to the action at its input of the signal from the output of the transducer of the active component of the current exceeding a predetermined level, is on.
