VarSet Fast capacitor banks are suitable for applications with dynamic load variation or for electronic loads that are sensitive to transient over voltages. This range is available from 450 kVAR to 1200 kVAR.

Reactive power compensation is typically performed by a dedicated controller which measures the system power factor, compares it to a set target and energizes capacitors via electromechanical contactors. Standard system response to a load fluctuation will be 5-10 minutes at best - provided the load increase remains constant at the new, higher level.

VarSet Fast utilizes electronic switching elements and a DSP-based controller capable of reacting within ten seconds (max.) to load fluctuations. The full value of the system is the transient free switching of the capacitor, and electronic switches having a virtually unlimited life.
