The basics of capacitor banks protection
Harmonic filters, for thyristor controlled reactors, are also variations of capacitor banks having the reactor inductance together with the capacitor capacitance tuned for series resonance at a certain frequency. The tuning are purposely a little bit incorrect, in order not to get a too low impedance for the harmonic, to which it is tuned.
