MAYAK 101ARTD

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.
  • Number of rates - 8.

Energy meter supports rate cards for each month of a year. Monthly rate card consists of daily rate cards for each weekday and the exceptional day.
Capability to set up to 32 exceptional days.

  • Liquid crystal display.
  • Communication interfaces optical port, radio modem (ZigBee equivalent), PLC-modem.
  • Programmable pulse output.
  • Built-in microcontroller.
  • Load control function (signal).
  • 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).

FUNCTIONAL CAPABILITIES

Energy meter ensures cyclic representation of the following data:

  • 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;
  • actual voltage value;
  • actual current value;
  • frequency;
  • actual temperature value (for reference only);
  • actual active power value of the forward and reverse direction;
  • actual reactive power value of the forward and reverse direction;
  • actual 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.

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 meters provide the capability to write rate cards, current time, weekday, date, month, year, energy and power limits, consumer category.
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:

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

Energy meter load control is effected via a signal which is sent:

  • on an external command;
  • when the preset limits of power network parameters are exceeded;
  • when the energy consumption limit is exceeded;
  • when there is an unauthorized access attempt;
  • Load tripping delay is assigned by using the software tools available.
