100 kVAr to 10 MVAr PCS100 STATCOM

The PCS 100 STATCOM is also suited for traditional industrial appliions. Industrial loads like arc furnaces, welders or big motors cause voltage disturbances and current distortion. A PCS100 STATCOM provides the ideal solution for voltage regulation, flicker mitigation, negative sequence compensation and harmonic can-cellation. User benefits

Technology - Comsys – Perfecting Power

ADF Power Tuning is the only solution with Sensorless Control, meaning we entirely remove the need for current transformers. In cases where reduced voltage distortion is the goal, we have the opportunity to directly reduce voltage harmonics instead of compensating the load current and then reduce voltage harmonics as a side effect.
