GEAR AND METHOD MEASURING ELECTRIC ENERGY Russian patent published in 2000 - IPC

Abstract RU 2144197 C1

FIELD: electrical engineering, measurement technology. SUBSTANCE: proposed gear measuring electric energy has current and voltage pickups, multiplexing circuit and analog-to- digital converter. Microprocessor controls operation mode of multiplexing circuit so that it ensures feed of current and voltage signals to converter in turn. Same microprocessor momentarily computes electric energy using two values of voltage that characterizes sample of current and three samples of current. Thanks to use of mentioned means one can correct optimally time delay between samples of voltage and current. EFFECT: enhanced accuracy of gear and method. 8 cl, 3 dwg
