Product code: 234 ART

APPLICATION

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 three-phase threeand four-wired AC networks with subsequent accumulated data storage, generation of events and transmission of information to the AMR/AMI system’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, inside cabinets or boards).

MODIFICATIONS

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 123 previous days;
  • energy at the beginning of the current month and 36 previous months;
  • energy at the beginning of the current year and previous year;
  • consumption for the current day and previous day;
  • consumption for the current month and 11 previous months.

— Metering of reactive energy by every quadrant in bidirectional meters.

— TOU with the option of setting individual schedule for every day of the week based on 4 tariffs, 16 time zones per day (24 time zones
per day (in meters with a DLMS/COSEM and SPODES protocol). Individual tariffs schedule for 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 for each phase with the total power vector direction indication;
  • RMS of phase currents and voltages including measurements at one period of frequency for power quality analysis;
  • phase angles;
  • power frequency;
  • power factors of each phase and of their sum;
  • THD of sinusoidal phase lines.

— Two independent power profiles with integration period from 1 to 60 minutes, the second profile can be configured as a 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.

— Built-in interfaces: optical port and RS-485 in all models.

— Optional built-in interfaces: PLC, RF, CAN, LoRaWAN, ZigBee.

— External backup power supply (6 – 12 V DC).

— Multifunctional galvanically isolated pulse output including the load control function.

— Automatic self-diagnosis with error indication.

— Built-in 60A or 100A relay.

— Two nonvolatile electronic crimped seals.

— Magnetic field sensor.

— Recording of unauthorized impacts into the indelible event log.

— Multifunctional LCD with backlight and OBIS-codes indication.

— LCD indication of data without main power.

— DLMS/COSEM and Mercury protocols support.

— Back-up power battery can be replaced without opening the meter housing.

— Meters have solid housing and transparent terminal cover for prevention from tamper.
