Static single-phase single-tariff electric meters SCHETPRIBOR SEO100
Electric meter
The meters are designed to measure active electrical energy in single-phase AC circuits.
The scope of application of the meters is metering of the consumption of AC active electric energy at enterprises and in the domestic sector.
The principle of operation of the meters is based on the use of the sigma - delta modulation method when multiplying the input voltage and current signals, followed by converting the signal into a pulse repetition frequency proportional to the input power. Summation of these pulses by the indicating device determines the amount of active electrical energy consumed, displayed on the reels of the electromechanical or on the screen (LCD) of the indicating device.
A shunt connected to the current circuit is used as a current sensor (measuring element) in the meters. A resistive divider is used as voltage sensors.
