Mercury 233 ÀRT

   Multi-functional electric energy meter Mercury 233 is designed to register active and reactive electric energy in one direction or two in three-phase 3 or 4-wired network by means of measurement transformers or directly with availability of tariff registration by day zones, long-term storage and accumulated data transmission through digital interface wire or wireless communication channels to data collection centers.

   Meters may operate both in stand-alone mode and in the structure of any information measurement system of technical and commercial registration.

    Among distinctive features of this meter model is two replaceable modules for maximum flexibility to construct data collection networks and availability of built-in load shed relay.

Functions:

  • Measurement, registration, storage, output to LCD display and transmission through interfaces data as follows: registered active and reactive energy separately under each tariff and by all tariff sum for the periods as follows:
    • total from reset;
    • for the current day and by the beginning of the day;
    • for the last day and by the beginning of the day;
    • for the current month and by the beginning of the month;
    • for each of the 11 previous months and by the beginning of each month;
    • for the current year and by the beginning of the year;
    • for the previous year and by the beginning of the year.
  • Meter tariff rater ensures separate tariff schedule for each day of the week taking into account excluded from registration days under 4 tariffs in 16 time zones of the day. Each month of the year is programmed according to individual tariff schedule. Minimum tariff interval within 24 hours makes 1 min.
  • Straight direction active energy registration is available separate in each mains phase.
  • Registration of technical loss in power lines and supply transformers is also available.
  • Additionally, meter ensure registration power mains parameters as follows:
    • instantaneous values of active, reactive and total power under each phase and sum by phases with total power vector indication;
    • actual values of phase current, voltage, phase voltage angles;
    • power factors under each phase and sum by phases;
    • sinusoidality phase curve distortion factor.
  • Two-channel archive storage of active and reactive energy average power and technical loss power profile with unspecified averaging time of 1-45min. When selecting 30-minute power edges, archive overflow time shall make 85 days.
  • Active and reactive power morning and evening peaks fixing at the specified interval with monthly schedule.
  • Event log (ringed, 10 records per each event) to fix:
    • meter switching on/off time;
    • 1,2,3 phase loss/occurence time;
    • meter opening/closing time;
    • tariff schedule correction time;
    • specified power surpassing time…
    22 various events in total
  • Power quality analyzer function (PQA) with recording voltage and frequency loss/reset time beyond normal and peak values in PQA log (100 records per each event);
  • Load control and management function by means of built-in or external disconnection relay. If the preset active power or energy limits are exceeded, meter disconnect user by itself or control user external devices for load shed (for example, emergency circuit breaker).
Technical Features
  • Accuracy class 0.2S, 0.5S, 1.0
  • Replaceable interface modules: RS-485, GSM, Bluetooth, PLC, RF, Ethernet, ZigBee;
  • Built-in interface – optical port;
  • Availability to connect back-up supply Ubackup = 5,5...16V;
  • Power, current, voltage, frequency, cosfi measurement;
  • 4 standard galvanically isolated telemetry outputs, one per each energy kind;
  • 1 load management output;
  • Meters operate towards values increase in case of any current circuits phasing connection failure (by module summing);
  • Automated self-diagnosis with error display;
  • Load management by means of built-in relay or external commutation circuits;
  • Electronic seal;
  • LCD backlight.
