    Three-phase imbalance automatic regulation device was developed after many years’ hard work of our company.
    Because there are many single loads in the apartments and rural power grids and there are randomness and asynchrony when loads are connected to the power grid, so the distribution transformer will be the status of asymmetric operation. Using YDK-SPC will make the three-phase loads to be balanced as much as possible

    Display Function

    * The controller adopts the LCD display panel which can display different operating and setup parameters.

    * The controller adopts the touch keys.

    * This device adopts the digital ampere meter which can display the operating currents directly.

    Parameters Set Function

    * Users can set over-voltage protection values, over-voltage shutting values, under-voltage protection values and other protection values.

    * Users can set delay times, switching-in threshold, switching-off threshold and other switching threshold value.

    * Users can set the ratio of current sampling transformer.

    Measuring Function

    *This regulator can measure distribution voltages, currents, power factors, active powers and reactive powers.

    Control Function

    * Users can choose auto or manual mode to control the capacitors’ switching. Switching depends on the reactive power value.

    * Same capacity capacitors work by the cyclic switching principle. Different capacity capacitors’ coding switching depends on the reactive power shortage.

    Protection Function

    * YDK-SPC includes harmonics protection, over-voltage protection, over-voltage shutting, under-voltage protection, default phase protection and under-current protection in the distribution system.

    Signal Function

    * YDK-SPC can display the operating status and capacity of each capacitor.

    * Display every threshold-crossing signal of distribution system parameters.

    * Display the fault of controller and capacitors.

    Operating Environment

    * Operating temperature: -20℃~+60℃

    * Relative humidity: ≤90% (20℃)

    * Atmospheric pressure: 79.5kpa~106.5kpa

    * Altitude: ≤3000m

    * There are not explosive and corrosive gases and conductive dust in the surrounding.
