PSCH-4.04.2

PURPOSE AND FIELD OF APPLICATION

   The meter is designed for accounting of active energy in three-phase three-wire or four-wire power circuits of a.c. with the frequency of 50Hz, independently or as a component of any automated systems for commercial energy accounting (ASKUE).

NORMATIVE AND LEGAL BACKING

    IEC 62052-11:2003

TECHNICAL FEATURES

  • Internal tasksetter.
  • The liquid-crystal display indicates  the amount of the consumed active energy in kilowatt-hour with the accuracy of one thousandth of a unit.
  • Nonvolatile memory.
  • Electronic seal (option).
  • Two programmable pulse outputs for commercial and technical  accounting.
  • RS-485 communication interface.

FUNCTIONAL CAPABILITIES

  • Exchange of information from a personal computer through RS-485 communication interface.
  • Registration and storage of the data on the consumed electrical energy as per each tariff zone with the possibility to scan the information on a liquid-crystal display:

  •     with total accrual accounting;
        for each  of preceding 11 months;
        with exceeding the power limit.
  • Registration and storage of energy data as per tariff zones as at the beginning of each half-hour in the course of 1,5 months (power profile).
  • Setting power and electrical energy limit.
  • Registration and storage of the time data when the meter was energized and de-energized and registration of the time when the meter’s terminal cover was opened.
  • Automatic changing-over to ‘summer’ or ‘winter’ time.
  • Assigning a tariff schedule for every day of the week, taking into consideration holidays, current time, day of the week, date, month, year, category of a consumer.
  • Transmitting a signal from the pulse output to the actuator, which switches on/off the consumer’s load when the consumer exceeds the fixed limits.
  • Protection against unauthorized changing of the information, entered and stored in the meter.
