(57) Abstract |
The multifunctional module executes the following functions: - measurement and accounting of active and reactive energy in forward and reverse directions in three-phase four-wire circuits of alternating current with frequency 50 Hz and organization of multi-tariff metering; - conversion, storage and transfer of information via built-in interfaces both independently and in automatic control and information acquisition systems; Field of application - electricity metering at industrial enterprises, public utilities and power facilities, including with data exchange via communication channels as part of automated commercial electricity metering system (ACEMS). The multifunctional module is based on the measurement by analog-to-digital converters of instantaneous values of input voltage and current signals in phases, followed by calculation by a microcontroller of active energy, as well as other network parameters: RMS values of voltages and currents, active, reactive and full power, reactive energy in total and in phases, active power factor in phases, network frequency. The multifunctional module includes: current sensors (shunts or current transformers), a microcontroller, non-volatile data memory, a built-in real-time clock that allows you to keep records of electric energy by tariff zones of the day, optical and electrical test output devices for calibration and verification, an LCD display for viewing measured information, sensors for opening the terminal cover, housing, exposure to a magnet, a radio field, and the temperature inside the meter. The multifunctional module is designed to connect to the network directly.
