the interface circuits are connected to the «ground» (the «ground» is a conductive foil film enclosing the meter and
attached to a flat conductive surface on which the meter base is mounted).
For transformer connection meters, the insulation withstands a voltage of 4 kV AC at 50 Hz for 1 minute, when
applied between current circuits connected together and voltage circuits connected together.

circuit output connected to the «ground», withstands pulse voltage of 6 kV.
The insulation between all current and voltage circuits connected together and with the «ground» can withstand
pulse voltage of 6 kV. During the test, the leads of the electrical test output device must be connected to the «ground».

20 MΩ — under conditions of clause 2.5;
7 MΩ – at an ambient air temperature (40±2) °С, relative air humidity of 93%.
1.6 The meter must be installed and operated in accordance with the applicable rules for technical operation of
electrical installations.
1.7 Do not put foreign objects on the meter, avoid bumps.
2 METER DESCRIPTION
2.1 Purpose
The meter is three-phase, transformer connection or direct connection (depending on the version), it is designed
to measure active and reactive electrical energy in three-phase four-wire AC circuits.
The meter has the following functions:
• multi-tariff electricity metering (with three tariffing levels - event-based, external and time-based tariffing);
• maintenance of the retrospective (recording the current values of energy storage devices: at the end of the
billing period (month), at the end of the day, at the end of the year and upon occurrence of a specific event);
• maintaining a load profile, with the ability to customize the type of the parameters stored and the averaging
time;
• measuring network parameters: voltage frequency, phase currents, phase voltages, phase-to-phase (line)
voltages (with non-standardized accuracy), angles between current and voltage by phases; power factor by phases
and the three-phase power factor, active, reactive, full power by phases and total;
• measuring Unified Power Quality Index (UPQI) in accordance with class «S» of the measurement process
specifications in IEC 61000-4-30:2008: stable voltage deviation, network frequency deviation, duration and depth
of voltage dips, duration and maximum value of overvoltage, interruptions in power supply;
• power quality analysis for compliance with quality standards in accordance with EN50160:2010;
• indicating the instance of violating an individual power quality indicator on the LCD (disabled by default);
6 7
• recording the violation of an individual power quality indicator (event logs available for reading on the interface);
• monitoring active power consumption;
• monitoring «instantaneous power» consumption;
• monitoring active energy consumption (control of energy limits, prepaid mode, low consumption control);
• monitoring mains voltage;
• monitoring currents;
• monitoring network frequency;
• monitoring phase sequence;
• monitoring phase break;
• monitoring oncoming power flow;
• alarm relay (in the versions of the meter with an alarm relay (see Table 2.2));
• telemetric outputs with the ability to use them as a «relay»;
• alarm using the interface (the ability to act as an initiator of communication with the level of DCU or HES during:
terminal cover opening; exposure to a magnetic field; reparameterization; maximum power excess; deviation
from the normalized value of voltage level, etc., in accordance with the full list, for details, see the user manual
САНТ.411152.107-05.1 РП;
• time accounting;
• self-diagnostics;
• information protection;
• protection against unauthorized opening (electronic seals);
• magnetic field sensor;
• event logs with recording of: terminal cover opening; case opening; dates of last re-programming; exposure
to a magnetic field causing unacceptable deviations of the metrological characteristics of the metering device; facts
of communication with the metering device that led to data changes; voltage deviations from the device’s nominal
values in the measuring circuits; results of self-diagnostics; changes in the current values of time and date during
time synchronization (at least 3,500 records using the DLMS/COSEM protocol.), etc., for details, see the user

manual САНТ.411152.107-05.1 РП;
• mechanism for flexible adjustment of the reaction to events occurring in the meter;
• DLMS/COSEM exchange protocol support;
• display of information on the LCD accompanied by OBIS codes;
• IEC 60870-5-104-2004 exchange protocol support;
• management of consumer load according to a predefined schedule.
A detailed description of meter functions is given in the full version of САНТ.411152.107-05.1 РП (User
Manual).
The meter can be used in Automatic Informational and Measuring Systems for Commercial Electric Power
Accounting (AMI systems) to transfer the measured or calculated parameters to the control room for controlling,
accounting and distributing electric power.
The measurement results are obtained through processing and calculating current and voltage input signals
performed by the microprocessor circuit on the meter board. The measured data and other information are displayed
on a liquid crystal display (LCD) and can be transmitted via an optical port, using one or two additional interfaces.
The meter has 2 communication channels. The PLC G3 communication module in metering devices operates on
the principle of a mesh network and provides search for duplicate routes for the guaranteed transmission of the
collected information.
The meter has an electronic counting mechanism which, depending on the established current and voltage
transformation ratios, records active and reactive energy in kW•h and kVar•h, respectively, overall and according to
eight tariffs in two directions.
Changing time of the counting mechanism indications complies with the requirements of IEC 62052-11:2003,
IEC 62053-21:2003 (IEC 62053-22:2003) and IEC 62053-23:2003.
