FIELD: measuring equipment.
SUBSTANCE: invention relates to the field of measuring and can be used to measure the amount of consumed electric power from a three-phase alternating voltage network. The meter is comprised of a plastic body made consisting of a main trough-shaped frame and an additional trough-shaped frame. A printed circuit board is installed in the main frame, connected by the supply leads to the corresponding leads of the three-phase alternating voltage network and to the load leads, with three voltage sensors, with a calculator for the amount of consumed electric power, with a constant voltage source, and with a unit for displaying the amount of consumed electric power in the form of a radio transmitter and a radio receiver. An additional printed circuit board with an additional radio transmitter is installed in the additional frame. The frames are interconnected by the respective edges. The current consumption sensor unit of phase wires is made in the form of a separate detachable rectangular body located with the longitudinal edges thereof in the recesses made inside of the main and the additional trough-shaped frames. The current consumption sensor unit consists of a printed circuit board with three current consumption sensors of phase wires placed thereon. The meter has a first connector and a second connector, providing the required connections of the elements of the meter.
EFFECT: improving operational capabilities and expanding the range of technical means.
