Main function of the product
Harmonic suppression function: Effective suppression of higher harmonics and inrush current rejection harmonics are entered into the capacitor device. It can eliminate the influence of higher harmonics on the capacitor, protect the circuit and capacitor overload, prevent the capacitor from overheating, the aging of the insulating medium, the self-healing performance is degraded, and the service life is reduced. Synchronous switching function: dynamic tracking can be realized with fast response time with dedicated controller, and it is accurately switched when the current voltage is zero, which is less affected by harmonics.
Split phase compensation function: Split phase compensation type product, each phase capacitor can be switched separately to improve the accuracy of reactive power compensation, so that the three-phase reactive power imbalance is well compensated.
Measurement function: distribution voltage, current, reactive power, power factor measurement, CT phase and ratio automatic measurement, calibration; three-phase current and internal temperature measurement of each capacitor.
Protection function: loop current speed cut, over current protection; capacitor overvoltage and undervoltage protection; capacitor overtemperature, phase failure, three-phase unbalance protection, when the capacitor temperature exceeds 65 degrees, the capacitor is returned to the whole machine to improve the service life and ensure the safe operation of the system.

Communication function: RS-485 communication connection between capacitor and controller, it is convenient for large-scale sampling data uploading and information exchange with peripheral monitoring terminals to form system work.
Intelligent network control: It can automatically detect and track the change of reactive power of the system and automatically switch thecapacitor bank.
Capacitors with the same capacity are subject to the principle of cyclic switching, and capacitors with different capacities are switched according to the principle of suitable compensation. Capacitors with the same capacity are subject to the principle of cyclic switching, and capacitors with different capacities are switched according to the principle of suitable compensation. Capacitors should be cast first, first and first; capacitor operating temperature is low first, and high temperature is first; when the compensation condition is constant, the capacitor is cycled every time period to avoid a single capacitor being put into operation for a long time.
