Accounting for active energy in three-phase four-wire and three-wire AC circuits. Transmission of information about measuring electrical energy to a data acquisition device (USD) for the organization of "Information and measurement systems" of commercial electricity metering.

Purpose Measurement of active and reactive electrical energy flowing in the forward and reverse directions, measurement of active and reactive power, current voltage values, power coefficients, frequency in three and four-wire AC networks. The use of Autonomous or as part of automated systems for control and accounting of electricity (ASC) and transmission using the available counter interfaces measuring and computing parameters to the control room for control, accounting and distribution of electric energy. Storage of energy (power) measuring values in the event log for 24 months with the issuance of half-hour values of power measuring values at the request of the operator, storage of daily maximums and minimums and average values of power storage time of network deviation and time of unauthorized access.

Inspection of loaded trucks and other vehicles, as well as containers in seaports and airports
