Mercury 230 ART
The meters are designed for unidirectional multi-tariff measurement of active and reactive electric energy and power, as well as electrical parameters in three-phase three- and four-wired AC networks with subsequent accumulated data storage, generation of events and data transfer to the AMR/AMI systemâ€™s data collection centers.
The meters are designed for indoor operation and can be installed in the areas with additional environmental protection (installed inside premises, cabinets or boards).
The meter modifications are available with different rated voltage, rated and peak current, and additional functionalities which are not related to metrological perfomance.

— The meter measures, stores, displaying on LCD and communicate information via different interfaces of active and reactive electrical energy independently by every tariff zone and cumulatively for all tariff zones for the following periods of time:
- total cumulative energy;
- energy at the beginning of the current day and the previous day;
- energy at the beginning of the current month and 11 previous months;
- energy at the beginning of the current year and the previous year;
- consumption for the current day and the previous day;
- consumption for the current month and 11 previous months.
— Energy measurement independently from current circuits phasing (measurement per module).
— TOU with the option of setting individual schedule for every day of the week based on 4 tariffs, 16 time zones per day. Individual tariffs schedule is set every month. Minimal interval of each tariff during 24 hours is 1 minute. Multi-tariff per-phase metering function.
— Measurement of technical losses in power lines and power transformers.
—Measurement of electrical network parameters.
- instantaneous values of active, reactive and total power per each phase and the total of all phases with the total power vector direction indication;
- RMS of phase currents and voltages ;
- phase angles values;
- power frequency;
- power factors of each phase and of their sum.
— Power profile and technical losses power profile with arbitrary integration period from 1 to 45 minutes. The storage period is 85 days for 30 minutes averaging time.
— Recording of morning and evening peaks of active and reactive power at a specified interval with a monthly schedule.
— Event logging including power quality events.
