◇Introduction
    SDCC series of low voltage reactive power compensation device for urban and rural power grid reactive power compensation, industrial and mining enterprises internal grid reactive power compensation. Can be installed on the poles of the 10/0.4kVV outdoor column transformer.
    The compensation counters to monitor real-time display of three-phase power parameters can be displayed at any circuit in the three-phase voltage, current, power factor, frequency, active power, reactive power, harmonic distortion. With RS232/485 communication interface.
   Implementation of national standards and specifications:
    IEC439 "Low-voltage switchgear and control equipment"
    GB7251 "Low-voltage switchgear"
    GB / T 15576-2008 "Low-voltage reactive power compensation device"
