What is Harmonic Filter (Detuned) Reactor? Why is used in …

If we look to the impedance equation of the capacitor, it is seen that the capacitor impedance decreases with the increase of the frequency. In this case, the current will flow at low impedance so that the total current on the capacitor will be equal to the sum of the nominal coupling current and the harmonic current.
