The reactor also helps to balance the current flow between the capacitors in the bank by limiting the current flow to the capacitor with the lowest impedance. However, the insertion of the reactor also raises the voltage across the capacitor, which can lead to increased voltage stress and a need for a higher voltage rating of the capacitor.
