Intelligent reactive power compensation device
◆It is controlled by intelligent controller with complete functions, reliable performance, automatic compensation mode;
◆It can improve the power factor to more than 0.9; real-time display of grid power factor, display range: lagging (0.00- 0.99), overrunning (0.00-0.99).
◆With over-voltage, over-harmonic, over-compensation, system failure, phase loss, overload and other comprehensive protection functions.
◆Memorize the set parameters, the system will not lose the parameters after the power outage, after the power grid returns to normal, it will automatically enter the operation state, no need to be manned.
◆According to the load balance condition of the grid, it can adopt split-phase compensation or mixed compensation.
◆Strong anti-interference ability, can resist the amplitude of 2000V interference pulse directly input from the power grid, higher than the national professional standards.
◆Rated voltage: 0.38-0.66kV;
◆Rated frequency: 50Hz;
◆Rated capacity: 1-600kvar;
◆Applicable voltage range: (0.85-1.1) times the rated voltage;
