Power Factor Correction: Capacitor Bank
A capacitor bank is a group of capacitors that are connected in parallel and installed in an electrical system. These capacitors help to absorb reactive power, which in turn reduces the amount of reactive power flowing through the system and improves the power factor. 4.
