Low-voltage capacitor banks Dynacomp

Thyristor-switched capacitor banks for power factor compensation of fast varying loads

The ABB's Dynacomp low-voltage thyristor-switched capacitor banks are used for ultra-rapid transient free power factor compensation and voltage fluctuation mitigation.

Applications

The Dynacomp low-voltage thyristor-switched capacitor banks can be used in any applications requiring short response times, large number of operations, transient free switching or large amount of reactive power. For example:

Harbor crane
Welding machines
Rolling mills
Oil drilling platforms
Lifts
Rubber mixer
Saw mills and tunnel drills which have very high switching rates
