    Technical features   u Instead of manual intervention, the achievement of automatic fling-cut and adjustment in accordance with the grid system reactive power and voltage control requirement makes it possible to compensate the reactive power automatically as well as to increase the system power factor, by which, in case of a sufficient compensation capacity, it will be ensured to retain the system power factor equal to or above 0.95.   u There is an achievement of non-contact electronic switch developed with the technology of thruster with two-way anti-parallel connection, which makes it possible to extend the service life of switches to a great extent.   u There are achievements of zero-triggering fling-cut, shock-free, flow-free and over-voltage, and non-introducing of transient state or harmonics.   u The fast switching makes it possible to complete the fling-cut of capacitor within 20ms.   u There are options of three-phase common compensation, separate phase compensation and mixed compensation.   u With the superior "e-dog software" circuit and fault-tolerant technology, it is made possible to automatically discover the runtime error and thoroughly eliminate the "crash" phenomenon.   u The unique “hardware circuit fault protection circuit” can ensure it will not cause output false operation.   u The controller has good human-computer interface, intelligent judgment, optimal control and quick response, realizes full digitalization, with liquid crystal display, and has the function of network communication, which can check the time, operation mode, fling-cut group as well as the voltage, electric current, power factor, active and reactive power of bus; It can check the fault information;   u The service life of the capacitor is extended.   u Improve static and dynamic stability of power system.   u There is a decrease of the imbalanced voltage and current, which is also an improvement of the voltage quality and stabilization of system voltage as well as restraining of voltage flicker.   u It gives a decrease of grid loss, efficient energy conservation, an improvement of the efficiency of electrical equipment, and an increase of transformer load.   u Complete protection measures (overvoltage, undervoltage, phase loss, over-current and short circuit etc ).   u The series inductance may prevent from harmonic amplifying and absorb part of the harmonic current.   u It is provided with full digital control, real-time detection and calculation of the amount of reactive power.   u There is a dynamic display for quality parameters of system power factor, voltage, current, frequency, active and reactive power and harmonic.   u There are functions of on-line parameter setting and parameters memory.   u The number of ways of fling-cut shall be displayed for indicating the conditions of work.   u Both manual and automatic fling-cuts are available with an easy and flexible operation.   u The RS485 and CAN communication interfaces are able to be connected with computers or other equipments.
