In configurations of this kind, serial reactors are connected to the capacitors. The serial reactors detune the circuit to a frequency below the 5th (or 3rd) harmonic, which is the most significant in a harmonic-rich environment. In Europe, detuning by a factor of 3.78 times the line frequency is most common, whereas in other parts of the world, in

Capacitors are connected in series to the reactor. These "detuned" PFC systems are scaled in such a way that the self-resonant frequency is below that of the lowest harmonic. Standard versions of EPCOS reactors from are available for rated voltages of 400 V and 440 V and with outputs of 10 kvar to 100 kvar at 50 or 60 Hz.
By adding an appropriately rated series reactor to the power capacitor, both elements form a low-pass resonant circuit (usually below the 5th) which prevents higher order
