The use of a reactor in a capacitor bank serves to prevent harmonic resonance. Capacitor banks can interact with the inductive elements of the power system, potentially causing resonant conditions that amplify harmonic currents.
Capacitor banks are often used to correct low-power-factor situations. In systems with large amounts of capacitance used to correct power factor, high-voltage distortion can cause resonance at system harmonic frequencies. This results in series-or parallel-resonant currents, which can be very damaging to the electrical system.
