Three-phase smart electricity metering device for installation on a power line support. The meter of transformer or direct inclusion is designed for measuring and accounting of active and reactive (or only active) energy in three-phase three and four-wire AC networks of direct and reverse (or only direct) directions, measurements of active and reactive electric power, measurements of network parameters.
The operating principle of the meter is based on measurement of input signals of voltage and strength of alternating current, as well as network frequency by means of analogue-to-digital converters with their subsequent processing by means of a specialised controller. The meter is for outdoor operation, "Split" architecture, housing type SP31.
A remote digital display is used to display measurements. The device is developed on the Russian component base as part of microprocessor K1986VU024 (produced by LLC "NARTIS").
Communication interfaces: Optoport, RS-485, RF, GSM, NBIoT.
