GGJ type reactive power automatic compensation is suitable for industrial and mining enterprises and residential buildings with AC 50Hz, three-phase 380V, and transformer capacity of 100KVA-1000KVA distribution systems, used for reactive power compensation. GGJ is designed to be used in conjunction with GGD type low-voltage distribution panels. It can automatically control grouped capacitors in 4-12 groups (steps) to be switched into or out of the grid at intervals of 10-120 seconds based on the grid's demand for reactive power compensation, thereby achieving automatic reactive power compensation, stabilizing the voltage quality of the power supply network, reducing losses in the transmission and distribution systems and transformers, and achieving the goal of energy saving and improving the power supply quality of the grid.

Scope of application: GGJ capacitor cabinets are suitable for various humid and dusty workshops. They are applicable to light textile, metallurgy, chemical, mining, machinery, and other industrial and mining enterprises, used in AC 50Hz, rated voltage 380V or 660V, rated current up to 630A three-phase three-wire, four-wire, or five-wire low-voltage distribution systems for power and lighting distribution. They can also be used for partial control in low-voltage control systems.
