ELECTRONIC ELECTRIC ENERGY METER Russian patent published in 1997 - IPC

FIELD: electric measuring equipment. SUBSTANCE: the meter uses a multiplier of signals of current and voltage transmitters, multiplication voltage-to-output signal frequency converter, time-division multiplier with averaging and switching of multiplication voltage polarity at the output of the low-pass filter; integrator of current and voltage of the adder of bias source and multiplier signals, generator of capacitor voltage compensation pulses by current from voltages of two compensation sources with a stable difference at a bias source voltage close to their half-sum; control signal generator for producing reverse signals corresponding to the sign of voltage increments at the capacitor of the integrator which consists of a clocked storage element and a solver element that changes the signal at the storage element output depending on the switching signal, output counter of increments of reference signal period count signals at different reverse signals. EFFECT: enhanced accuracy and reliability, expanded range of meter regulation. 20 cl, 2 dwg
