FIELD: measuring technique. SUBSTANCE: electric power meter, having a device for current and voltage inlet (input busbars), an integrator, three comparators, a reference voltage (current) source, a reference frequency generator, a logic gate unit, a reversive pulse counter and an indicator, provides elimination of additive error component by introduction to a voltage channel a paraphase controllable inverter, by using a controllable inverter in a current channel and a unit for controlling both above mentioned inverters. EFFECT: enhanced accuracy of metering due to eliminated error component. |
