PURPOSE AND FIELD OF APPLICATION

    The meters are intended for metering of active electrical energy in two-wire power circuits of alternating current with the frequency of 50Hz.

    The data on power consumption is indicated on the electrical and mechanical reading device which is protected from electromagnetic influences. Due to telemetric data output of the meters they can be used as a component of any automated systems for commercial energy accounting.

NORMATIVE AND LEGAL BACKING

    IEC 62052-11:2003

TECHNICAL FEATURES

  • The electrical and mechanical reading device indicates the amount of the consumed power in kilowatt-hour with the accuracy of one hundredth of a unit.
  • LED indication of the current in the load circuit: the more the load, the more often the LED blinks.
  • Reading devices with the reverse motion lock and protection from electromagnetic influences, which exceed the requirements of GOST 30207-94, are used in the electricity meters .
  • The electricity meters are  provided with a pulse output, which is galvanically separated from the network and ensures transmission of information on the quantity of active energy to a remote data collection system through a two-wire communication line.
