Mercury 208 ART
The meters are designed for uni- and bidirectional multi-tariff measurement of active and reactive electric energy and power, as well as measurement of electrical parameters in two-wired AC networks with subsequent accumulated data storage, generation of events and transmission of information to the AMR/AMI systemâ€™s data collection centers.
The meters are designed for indoor and outdoor operation including mounting onto pillars.
The meter modifications are available with different rated and peak current, and additional functionalities which are not related to metrological perfomance.

— The meters have split architecture (split-meters) and are equipped with a remote display for remote reading.
— The remote display receives data from a meter via a radio channel simultaneously and independently of data exchange between the meter and the AMR/AMI system.
— 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 123 previous days;
- energy at the beginning of the current month and 36 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.
— Reactive energy metering per quadrant.
— TOU with the option of setting individual schedule for every day of the week and month based on 4 tariffs, 16 time zones per day (24 time zones in meters with a DLMS/COSEM, SPODES* protocol). Individual tariffs schedule is set every month. Minimal interval of each tariff during 24 hours is 1 minute.
— Measurement of technical losses in power lines and power transformers.
— Measurement of electrical network parameters:
- instantaneous values of active, reactive and total power with the total power vector direction indication;
- RMS of phase currents and voltages including measurments at one
- period of frequency for power quality analysis;
- power frequency;
- power factor;
- THD of sinusoidal phase lines.
— Two independent power profiles with integration period from 1 to 60, the second profile can be configured as technical losses power profile. The storage period is 170 days for 30 minutes averaging time.
— Recording of morning and evening peaks of active and reactive power demand at a specified interval from 1 to 60 minutes with a monthly schedule.
— Event logging including power quality events.
— Additional built-in interfaces: PLC, RF, LoRaWAN.
— Automatic self-diagnosis with error indication.
— Built-in 100A relay.
— Two nonvolatile electronic seals.
— Magnetic field sensor.
— Recording of unauthorized impacts to the indelible event log.
— DLMS/COSEM and Mercury protocols support.
— Additional current sensor in neutral wire (optional).
— Meters have solid housing for tamper prevention.
