METHOD OF MEASUREMENT OF QUANTITY OF DC ELECTRIC ENERGY Russian patent published in 1998 - IPC

Abstract RU 2103696 C1

FIELD: measurement technology. SUBSTANCE: frequency-modulated signal of input current and voltage product (electric power) is formed by alternate integration of input current signal and reference signal (in first time interval) and correction of zero shift of integration device (in second time interval) depending of frequency-modulated signal of voltage. EFFECT: higher accuracy of measurements. 2 cl, 1 dwg
