Low Voltage Intelligent Reactive Power Compensation Cabinet

GGJ Series Low Voltage Intelligent Reactive Power Compensation Cabinet


GGJ Series Low Voltage Intelligent Reactive Power Compensation Cabinet (also known as RPC cabinet, or Auto Power Factor Improver Cabinet APFI, Automatic Power Factor Correction Cabinet APFC) adopts advanced power electronic technology and intelligent control technology, which can effectively improve the power factor of the electrical load, reduce line loss, improve the actual load capacity of the transformer, and have a significant energy-saving effect. At the same time, the use of specific reactors in the system can also help prevent harmonic amplification and effectively absorb most of the harmonic currents. On the one hand, the GGJ series effectively solves the problem of automatic switching of parallel capacitors under harmonic conditions; on the other hand, it can filter out harmonics according to the actual requirements of users, clean the grid environment, reduce losses, and eliminate harmonic harms, and provides capacitive reactive power to the system to improve the power factor. GGJ series is often used in power distribution systems in electric power, metallurgy, petrochemical, industrial and mining, construction, machinery and other industries. The GGJ series is especially suitable for power transmission and distribution systems with frequent changes in load and unstable reactive power.
