GGJ is a capacitor cabinet dedicated to low‑voltage automatic reactive‑power compensation. Its main functions are to improve grid power factor and reduce line losses. Normally used together with GGD low‑voltage distribution panels, it can automatically switch 4‑12 groups of capacitors within 10‑120 seconds according to system reactive‑power demand to realize dynamic compensation. Suitable for 380 V power‑distribution systems in industrial‑mining enterprises and civil buildings, it effectively improves power quality so as to realize energy‑saving and consumption‑reduction.
