Industrial Purpose Capacitor Damping Reactors are used for limiting the inrush currents occurring during the switching of capacitor batteries to AC networks. The Reactors are single-phase or three - phase, usually dry-type, self-cooled, with air core, for indoors or outdoors installation. The Reactors are able to withstand a rated inrush current, which must be high enough to cover all recognized cases of switching the capacitor battery or battery sections. The Industrial Purpose Capacitor Damping Reactors are used to detune capacitor banks to avoid resonance with the power system.
