Learn MoreA capacitor bank is a group of several capacitors connected in the series or parallel combinations. Capacitors are electrical and electronic components that store electrical energy. Thus, capacitor banks (cap bank) stores the reactive energy (leading) and it compensate for reactive energy (lagging), and improves the power factor.
