   Multitariff meters

SEB-2.05.2

PURPOSE AND FIELD OF APPLICATION

    The meter is designed for multitariff accounting of active energy in two-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

  • Nonvolatile memory.
  • Internal two- or three-tariff tasksetter.
  • The liquid-crystal display indicates the amount of consumed electrical energy, current tariff, date, time, monthly consumption, tariff schedule of the current day.
  • RS-485 communication interface or optoport.
  • Programmable pulse output.
  • Electronic seal (option).
  • Structure of tariff schedule: 9 tariff zones, 8 day types.

FUNCTIONAL CAPABILITIES

    The electricity meter ensures:

  • exchange of information and programming of the meters from a personal computer through RS-485 communication interface or an optoport depending on the meter modification;
  • registration and storage of the data on the consumed electrical energy with the possibility to scan the information on a PC, a liquid-crystal display as per three tariffs: with total accrual accounting; as at the beginning of each preceding 11 months;
  • setting of power and electrical energy limit;
  • transmission of a signal from the pulse output to the actuator, which switches on/off the consumer’s load, after the consumer exceeds the fixed limits;
  • registration and storage of the time data when the meter was energized and de-energized;
  • 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.
