Capacitor Banks: What is a Capacitor Bank? Advantages & Uses
A Definition. As the name implies, a capacitor bank is merely a grouping of several capacitors of the same rating. Capacitor banks may be connected in series or parallel, depending upon the desired rating. As with an individual capacitor, banks of capacitors are used to store electrical energy and condition the flow of that energy.
