MAYAK 103ART

PURPOSE

Energy meters are designed for accounting of active and reactive energy of the forward and reverse direction in AC single-phase networks with the rated frequency of 50 Hz.
Energy meters may be used both in standalone mode and as part of automated measuring and information systems for electric power fiscal accounting (AMIS EPFA).

TECHNICAL FEATURES

  • Non-volatile RAM
  • Rate card structure - 8 rates, 8 day types, rate plan:
    • - for 8 day types and 12 months (a separate one for each weekday of a month with due account for holidays);
    • - flat rate for the whole of the year per 8 day types;
    • - flat rate for the whole of the year per single day.
  • Capability to set up to 32 exceptional days.
  • Communication interfaces - optical port, RS-485, PLC, RF 2400 MHz, GSM.
  • Programmable pulse output.
  • Load control function (relay or signal).
  • Built-in microcontroller.
  • Built-in real-time clock.
  • Enhanced security (two access levels common and individual passwords; capability to record date and time of the last energy meter disconnection from the power network, last energy meter switching on).
  • Resistance to climatic, mechanical, thermal and electromagnetic effects.

FUNCTIONAL CAPABILITIES

Non-volatile RAM of energy meters provides for recording, storing and read-out of the following values:

  • running total of active and reactive energy of the forward and reverse direction measured according to rates available from the date of manufacture;
  • active and reactive energy of the forward and reverse direction measured at the beginning of each month according to rates available over a three-year period;
  • active and reactive energy of the forward and reverse direction measured at the beginning of each day according to rates available over a 125-day period;
  • active and reactive energy of the forward and reverse direction measured for each half-hour over a 125-day period;
  • minimum and maximum values of line-to-ground voltage measured for each half-hour over a 125-day period;
  • minimum and maximum values of line-to-ground voltage measured for each day over a 125-day period;
  • energy meter event log;
  • energy quality indices log.

Energy meters provide the capability to generate and maintain the event log, where time of occurrence and time of completion of the following events are being recorded:

  • date and time of de-energizing and re-energizing (150 entries);
  • date, time and cause3 load break switch tripping and its cause (100 entries);
  • date and time of load activation (100 entries);
  • date and time of rate card reprogramming (150 entries);
  • date and time of maximum power value change in case of limiting energy consumption (100 entries);
  • maximum power value at the moment of tripping command generation (100 entries);
  • status data on malfunctions and errors in operation of energy meter main components (100 entries);
  • date and time of energy meter housing cover opening and resealing (150 entries);
  • date and time of terminal box cover opening and resealing (150 entries);
  • date and time prior to and upon the time adjustment (150 entries);
  • date and time of energy quality indices deviations (150 entries).

Energy quality indices logs are used to record time of going beyond / return into the preset upper / lower normally / maximum allowable bounds of:

  • effective value of the network voltage;
  • network frequency;
  • voltage excursion;
  • temporary overvoltage factor.

Energy meters provide the capability to write rate card, current time, weekday, date, month, year, energy and power limits.
Energy meters ensure cyclic representation of the following parameters:

  • accumulated active and reactive energy of the forward and reverse direction according to rates available and on an aggregate basis;
  • accumulated active and reactive energy in modulus irrespective of direction according to rates available and on an aggregate basis;
  • date and time;
  • effective voltage value;
  • effective current value;
  • frequency;
  • instantaneous temperature value (for reference only);
  • effective active power value of the forward and reverse direction;
  • effective reactive power value of the forward and reverse direction;
  • effective full power value of the forward and reverse direction;
  • cos φ (for reference only);
  • tg φ (for reference only);
  • effective rate;
  • built-in battery status;
  • status of built-in modems.

Energy quality indices may be read off the following interfaces:

  • network voltage deviation (for reference only);
  • network frequency deviation (for reference only);
  • value of measured temporary overvoltage factor (for reference only);
  • voltage excursion (for reference only).
