SET-4.02.2

PURPOSE AND FIELD OF APPLICATION

    The meters are intended for multitariff commercial or technical accounting of active and reactive electrical energy of the forward and reverse direction in three- and four-wire power circuits of alternating current, in case of current transformer connection and voltage transformer or direct voltage connection.

    The electricity meters can be used  in production enterprises and in electric energy systems, can register  power flows in electric energy systems and intersystem overflows.
    The meters can be used either independently or as component of automated systems for commercial energy accounting (ASKUE).

NORMATIVE AND LEGAL BACKING

    IEC 62052-11:2003

TECHNICAL FEATURES

  • Digital signal processing.
  • Two communication interfaces: RS-485 and optoport.
  • Built-in real-time clock.
  • Four pulse outputs.
  • Nonvolatile memory.

FUNCTIONAL CAPABILITIES

    The meters ensure multitariff accounting of active and reactive energy of the forward and reverse direction in eight tariff zones, as per eight day types in twelve seasons. Minimum tariff zone interval is 10 minutes. Maximum number of tariff zones in a daily tariff schedule is 144.

    The meters keep records of the measured active energy with the possibility to indicate them on the display and to read them through the communication interfaces: in total from the date of meter resetting; for the current and preceding years; for the current month and for each of preceding 11 months, for the current and preceding day.

    The meters keep a  power profile array with programmable integration time from 1 to 30 minutes for active and reactive power of the forward and reverse direction. Storing depth of each power profile array with integration time of 30 minutes is 3,7 months.

    The electricity meters keep event logs, power-quality logs, logs concerning power threshold exceeding and a status log.

    The electricity meters measure instantaneous values of physical quantities, characterizing three-phase power network, and can be used for measuring:

  • active, reactive and total power;
  • phase voltage and voltage between phases, positive-sequence voltage;
  • current;
  • power factor;
  • network frequency;
  • waveform distortion factor of phase voltage and voltage between phases;
  • zero-plus-negative-phase-sequence voltage unbalance factor.

    The meters can be used as power-quality meters under parameters of steady-state deviation of phase voltage (voltage between the phases, positive-sequence voltage) and network frequency with measurement errors as specified in the Technical Specifications.

    The meters provide the possibility to programme, reprogramme, control and read parameters and data through RS-485 interface and optical port.
