  • Integrated device suspended at high voltage potential for power energy metering and protection of distribution network
    Patent number: 9018938
    Abstract: An integrated device suspended at a high voltage potential for the metering and protection of a distribution network comprises a measurement current transformer (CT), a protective CT and a voltage sensor. The voltage signal is output from the voltage sensor to an electric energy metering module and first and second electric signal acquiring modules. The current signal acquired by the measurement CT is output to the electric energy metering module. The current signal acquired by the protective CT is output to the first and second electric signal acquiring modules. The electric energy metering module processes the current and voltage signals and sends the processed data to a comprehensive control module. The first and second electric signal acquiring modules send the voltage and current data to the comprehensive control module. The comprehensive control module comprehensively calculates the received data and sends the result to a low voltage terminal.
