PSCH-4ÒÀ.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

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.
