GAMA 300

GAMA 300

New meter GAMA 300 is developed for a very rapidly changing electricity market, adapted to deregulation and customers' growing demands. Electronic electricity meter GAMA 300 operates in three-phase electricity networks and is approved in accordance with the standards IEC 62052-11, IEC 62053-21, IEC 62053-23, EN 50470-1 and EN 50470-3. The electricity meter satisfies the requirements of Directive 2004/22/EC of the European Parliament and of the Council of 31 March 2004 on measuring instruments.
Meter has optical and electrical communication interfaces and additionally can be equipped with internal communication modules upon request, allowing easy connection of meters to AMR system directly. GAMA 300 meter can have changeable (without uninstalling meter from site) Li-ion battery and internal relay for remote user disconnection.

Features:

Measuring

Meter operates in three-phase electricity networks and measures:
  • Active energy (bi-directional or unidirectional) with accuracy class 1.0 (B) or 2.0 (A) or
  • Active energy (bi-directional or unidirectional) with accuracy class 1.0 (B) or 0.5s (C) and Reactive energy (import-export) with accuracy class 2.0 (IEC 62053-23)
  • Active energy (bi-directional or unidirectional) and Reactive energy (import-export and/or in 4 quadrants)
  • Maximum Demand with date & time in meters with internal clock
  • Contractual power limits registration
  • [Optional] Load profiles
  • [Optional] Instantaneous values (A, V, kW, kVAr, kVA, cos φ) of each phase

    • Tariff module

    Meter GAMA 300 can be single-tariff or multi-tariff. Multi-tariff modification of the meter GAMA 300 has internal real-time clock with Li-ion or Super-cap backup and complex tariff structure (Time-Of-Use):

    Billing

    At the end of the billing period, the billing period reset signal triggers the storage of the current values to the non-volatile memory. The billing period reset may be initiated:
  • Manually:
    		• by pressing push-button;
  • Automatically (programmable):
    		• on decade days;
    on ½ month;
    on predefined day

    Data storage

    GAMA 300 meter has non-volatile memory, which allows to store metering data without influence of power outages. Capacity of stored data:
  • Total energy
    		•  from installation date;
  • Monthly energy
    		• of last 16 months;
  • Daily maximum demand values
    		• up to 480 days;
  • Monthly maximum demand values
    		• of last 12 months;
  • Events logbook records
    		• up to 100 records of each event type;
  • [Optional] load profiles
    		•  up to 10 (programmable) channels.

    Load Profiles [Optional]

    In order to help utilities and customers to meet deregulated market needs, meter GAMA 300 can have load profiles:
  • Load profiles capacity
    		• up to 360 days with integration period 60 minutes;
  • Programmable integration period
    		• 1, 5, 10, 15, 20, 30 or 60 min.

    Communications

    Meter has optical communication interface in accordance with IEC62056-21 or DLMS. Optical communication interface allows the user to read data and program meter in the field or in the workshop. GAMA 300 meter can have up to two electrical communication interfaces, allowing connection of meters to AMR system through external GSM/GPRS, RF, PSTN and LAN controllers:
  • Primary electrical communication interface:
    • 20 mA current loop (protocols: IEC 62056-21 or IEC 62056-31 or DLMS)
  • [Optional] available auxiliary electrical communication interfaces:
    • 20 mA current loop (protocol IEC 62056-31 or DLMS)
    • RS485 (protocol IEC 62056-31 or DLMS)
    • RS232 (protocol IEC 62056-31 or DLMS)
    • M-bus (protocol M-bus) for retrieving data from Water, Gas, Heat meters
    [Optional] Also meter can have internal PLC, GSM/GPRS or RF communication modems, allowing connection of meters directly to AMR system.

    Outputs/Inputs

  • Up to 4 electric pulse outputs (S0);
  • Up to 2 LED test outputs [Optional];
  • Clock synchronization input [Optional];
  • Relay, normally open contacts are connected:
    • When specified energy tariff is valid;
    • For two programmed periods during the 24-hour interval (periods are set in 15 minutes step).

    [Optional] Internal disconnection relay

    Internal disconnection relay is used to disconnect/reconnect electricity to the user. User disconnection may be done by the following means:
  • Automatically when contractual power limit is exceeded;
  • By external signal through communication interfaces.
    The user himself does reconnection by pressing a scroll-push button on the meter. This ensures maximum safety to the user.

    • Security features

    Hardware protection allows only authorized persons to access meter:
  • Two seals on main cover;
  • Two seals on terminal cover;
  • Improved resistance to permanent magnetic field;
  • Seal on battery cover;
  • [Optional] Sealed optical communication interface unblocking.
    • Software protection allows only authorized persons to program meter with software for meter programming and data reading:
  • Meters programming feature is protected by a password; if incorrect password is entered four times in a day, the password acceptance will be locked for 24 hours. During that period meter programming is impossible.

    • Meter with internal clock has Events logbook, registering the following events:
  • Power outages
    		•  up to last 32 events with date & time
  • Phase sequence change
    		•  up to last 10 events with date & time
  • Missing of any phase voltage
    		•  up to last 10 events with date & time
  • Meter programming
    		•  up to last 20 events with date & time
  • Internal errors
    		•  error code, last event with date & time
  • Magnetic field influence
    		•  up to last 10 event with date & time
  • Reverse current flow
    		•  up to last 10 event with date & time
  • [Optional] main cover openings
    		•  up to last 10 event with date & time
  • [Optional] terminal cover openings
    		• up to last 10 event with date & time

    Display

    GAMA 300 meter is equipped with LCD (Liquid crystal display). LCD contains 8 digits with programmable decimal point: 8-5 for whole numbers and 0-3 digits for decimal numbers. LCD displays majority of data accumulated in meter and parameterization constants. Features:
  • Cyclic (automatic) and static (manual) data scroll;
  • Data indication on LCD during power outages;
  • Reverse current flow indication;
  • Energy direction, load quadrant, phase sequence indicator;
