For the highly sensitive loads which do not tolerate fluctuations in system voltage, the ReactiVar® TFRC System removes the worry of how to perform power factor compensation and/or harmonic filtering where conventional systems are not adequate.
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.
The TFRC system 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.
