The ideal solution is to insert block reactors in series with capacitor banks.

When the reactor is connected in series with the front end of the capacitor, theworking voltage of the capacitor will be increased, and the increase factor = 1 / (1-reactance rate).
This resonance can be avoided by putting a detuned reactor in series with the capacitor. The reactor shall be such that the tuning frequency with the capacitor shall be less than the dominant harmonics. This combination of power factor correction capacitor and detuned reactors behaves inductively to frequencies above the tuning frequency.
Reactor capacity = matching capacitor capacity x reactance rate. For example, if 50kvar capacitor is connected in series with 7% reactor, then reactor capacity = 50kvar x 7% = 3.5kvar. Reactance ratio refers to the ratio of reactance value of series reactor to capacitance reactance value of capacitor bank.
