Three-phase transformer or direct connection meter is designed for active and reactive electric energy measurement and organization of single- and multi-tariff electric energy metering.

Functional capabilities
Multi-tariff electric energy measurement with a wide range of tariff schedule settings.
Bidirectional active and reactive energy measurement.
Support of IEC 62056-21 and DLMS / COSEM data exchange protocols (or ?Smart Metering? protocol).
Data transmission with automatic switch between PLC and RF communication channels on every transmission level (for PLC + RF model only).
Flexible adjustment of reaction to the events occurring in the meter.
Electric energy quality measurement:
voltage deviation;
network frequency deviation;
duration and depth of power failure;
duration and maximal value of overvoltage;
blackouts.
Load profi le logging, with an ability to set the type of parameters to save and averaging time for registration.
Network parameters metering according to EN 50160:2010:
voltage frequency;
currents;
voltages;
angles between current and voltage;
power factor;
active power;
reactive power;
apparent power.
Active power consumption control.
?Instantaneous power? consumption control.
Active energy consumption control.
Voltage of power supply control.
Network frequency control.
Signalization relay.
Unauthorized opening protection (electronic seals).
Magnetic fi eld sensor.
Data logging for:
measured data registration (total and per tariff) for active and reactive energy by day changing;
measured data registration (total and per tariff) for active and reactive energy by month changing (with programmable date when the billing period ends);
measured data registration (total and per tariff) for active and reactive energy by year changing;
measured data registration (total and per tariff) for active and reactive energy per event or command.
Load control by external switching unit.
Sound alarm.
Self-testing.
LCD backlight.
Displaying of data supported by OBIS codes.
Range of use
Meter can be used as a part of AMI system for measured parameters transition to the control, metering and electric energy distribution center. Case type is designed for the installation on the mounting surface.
