Main function

●Filtering

Effective higher harmonics and inrush current,and make the high harmoincs to form a low impedance path.Discharge and absorption of the harmonic current,can eliminate the effect higher harmoincs on the capacitor,and protect the capacitor circuit and overload,and prevent overheating of the capacitor,dielectric aging,self-healing performance degradation and reducing service life.

●No inrush current switching function.

With special capacitor switching，no inrush current switching.

●Phase compensation

Phase compensaiton products,each pahse capacitor can respectively switching,and improve the accuracy of reactive power compensation,which will help three-phase reactive power imbalance to get well compensation.

●Measurements

Distribution voltage,current,reactive power,power factor measurement;CT phase and variable ratio automatic measurement,correction;three-phase current of the capaciotor,the body temperature measurement.

●Protection

Loop current rate cut,over-current protection;capacitor over voltage,under voltage protection;capactior over-temperature,phase failure,phase unbalance protection,when the temperature exceeds 65 degrees,capacitor returned machine protection,improve service life,and ersure the system operation safely.

●Signal functions

Capacitor switching,owed compensation,and over voltage signals,protection action type,and self-diagnostic fault type signals.

●Communication

Using RS-485 communication association between capacitor and the controller, to facilitate a large number of sampled data upload and exchange information with peripheral monitoring terminal, then form the system work.

●Online features

The wired network and wireless network communication capabilities.

●Intelligent network control

Automaticly detecting and tracking sysemic reactive changes, automatic switching caacitor.Same capcitor switching by the principle of cyclical switchover, the different capacities switching by the priciple of apropriate commpensation.Before the first vote back,back before the first vote.capacitors with low operating temperature of the first vote,the high operating temperature of the first withdrawal;compensation condition is constangt ,the capacitor switchiing cycles perfifteen minutes,to avoid the single capacitor to put into operation a long time.

●Fault self-diagnosis function

Intelligent capacitor control components can be self-diagnosis the operating parameters,once the self-test failure,the whole fast response,quit running.
