Abstract. Electronic meters provide a wider range of input voltages, make it easy to organize multi-tariff metering systems, allow you to review the amount of energy consumed over a period of time, measure power consumption, fit easily into the configuration of ACE systems and have some additional service features that include microcontroller software. is an indispensable attribute of a modern electronic electricity meter.
It is known that one of the costly articles of the installation of the ACMS system is a meter. Its features depend on the characteristics and capabilities of the entire system.
The purpose of the study is to substantiate and study the device of continuous technological accounting of electric energy on each phase of each line with the possibility of long-term accumulation, storage and quick output of the measurement results.
A device has been developed for continuous technological accounting of electrical energy for each phase of each power line, with the possibility of long-term accumulation, storage and rapid output of the measurement results.
The system consists of separate measuring units (up to 256) and a data collection server. The reports generated from the database obtained from the measurement units allow for a deep detailing of all the main parameters (voltage, current, full power, active power, reactive power, power factor) not only for a single line, but also for a separate phase. The total error in the calculation of electricity is 5 %, which can be considered sufficient for technological accounting.
The control units of the condenser units can be connected to the measuring units in order to increase the value of the power factor and to be integrated into the relay protection system.
Key words: electric power, metering, power, chip, binary code
