Intelligent Capacitor Compensation Cabinet Low Voltage Reactive Power Low Voltage Products
Product Overview:
GGJ capacitor compensation cabinet is a controller for compensating reactive power in low voltage distribution system. GGJ capacitor compensation cabinet is mainly used in low-voltage power distribution room, parallel with the distribution panel, used for centralized compensation of reactive power of the system, improve the power factor, reduce the non-power consumption of the system, and improve the power quality. GGJ capacitor compensation cabinet can automatically change the compensation capacity according to the change of reactive power of the system, so as to achieve better compensation effect.

GGJ Capacitor compensation cabinet market background:
With the development of modern industry, power electronic equipment is widely used in electric enterprises, which seriously results in low power factor of power grid. Moreover, most power factors of power electronic devices such as high-power converter and frequency conversion used in power are low, thus increasing generator loss, affecting voltage of power grid system, affecting reactive power flow distribution of power grid, and increasing power loss in the process of power transmission. In this case, we develop a low-voltage reactive power automatic compensation device for this phenomenon, to provide necessary reactive power compensation, reduce energy consumption, improve the quality of power grid voltage, so as to improve the service life of machinery.
