GAMA 300
Three phase electronic electricity meter GAMA 300 is
developed for a very rapidly changing electricity market, adapted to
deregulation and customers' growing demands. Meter measures active and reactive
energy up to six tariffs, upon request can record power peaks, accumulate load
profiles and have an internal relay for user disconnection. Approved in
accordance with the standards IEC 62052-11, IEC 62053-21, IEC 62053-23, EN
50470-1 and EN 50470-3.
- Measurement of active energy (bidirectional), reactive energy (in 4-quadrants) and maximum demand;
- Accuracy class 1.0 (B) or 0.5s (C);
- Measurement in four channels (in phase and neutral lines)(optional);
- Single or Multi-tariff (up to 6 tariffs);
- Internal real time clock;
- Load and billing profiles, instantaneous values;
- Extended anti-tamper features;
- Event logbook (power outage, power over-limit, reverse current flow, influence of magnetic field, opening of meter cover, opening of terminal cover, clock setting, parameter change, internal error, firmware update);
- Optical and electrical communication interfaces in accordance with IEC 62056-21 and/or DLMS/COSEM;
- Internal communication modules (PLC modem, USB host, wireless or wired MBus, RS485, Ethernet), powering of external modem;
- High-level security (encryption and authentication);
- Internal relay for user disconnection;
- Power quality monitoring (over-voltage, under-voltage, over-current);
- Measurement of Total Harmonic Distortion (THD);
- Registration of line and transformer losses on the basis of I2h and U2h
measurements.
