FIELD: measuring instruments.
SUBSTANCE: electric power users are connected to an electric supply network via gauges disposed in the points of direct connection to a 0.4 kV electric distribution network. Moreover, the gauges consist of an electric power meter, a control unit, a high-pass separation filter, a first power line modem connected directly to the 0.4 kV electric distribution network and a second power line modem connected to a user's electric supply line. Electric power consumption data are transmitted from the meter via the second power line modem to supply leads of the user's electric supply line and received via a third power line modem.
EFFECT: reducing electric power losses.
