Reactors and capacitors: how to couple them | Ortea Next
The ideal solution is to insert block reactors in series with capacitor banks. The power factor correction system devised thus, as well as continuing to perform the function of correcting the power factor, anticipates the amplification of the harmonic distortions caused by the resonance between the capacitor''s capacity and harmonic …

How to select a capacitor bank for power factor correction?
If 4% < THD(u)% ≤ 7% we suggest a heavy duty PFC capacitor bank with suitable harmonic detuned reactors; If THD(u)% > 7% we recommend the installation of an active harmonic filter . Finally, if both THD(I) and THD(U) are measured and do not result in the same type of power factor correction, you must chose the most rigorous solution.
