KBS-12 primary and secondary fusion ring cage

The primary and secondary integrated environmental gas ring cage is an intelligent complete set of equipment introduced in response to the new National grid standard "Technical Standard for primary and secondary complete sets of equipment for Power distribution", which integrates electromagnetic voltage, current transformer, energy metering module, high-speed fault transient wave and other technologies. It consists of loop in loop out unit, feeder unit, bus equipment (PT) unit, centralized DTU and connecting cable. It can collect active power, reactive power, power factor, frequency, zero sequence current and zero sequence voltage, and has the functions of line loss measurement and electric energy measurement, as well as line voltage identification, voltage limit, load limit alarm transmission, short circuit fault detection and processing, single-phase ground fault detection and processing, and supports short circuit/ground fault events transmission to meet the automation req
