GGJ Low voltage intelligent reactive power compensation cabinet

Product Overview
The GGJ low-voltage intelligent reactive power compensation cabinet is specially designed for the actual situation of the power grid. It adopts intelligent control technology, which effectively solves the problem of automatic switching of parallel capacitors for reactive power compensation under harmonic conditions. On the other hand, it can filter out harmonics according to users' actual requirements, clean the power grid environment, reduce losses, and eliminate harmonic hazards; And provide capacitive reactive power to the system to improve power factor. Can be used in power distribution systems for industries such as electricity, metallurgy, petrochemicals, industrial and mining enterprises, construction, and machinery
