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.

Teaching Substation Battery Testing to Undergraduates
TY - CPAPER AB - Battery banks are crucial for the proper operation of an electrical power substation. When station service power is lost, the battery bank must power 1) the tripping and closing of circuit breakers, 2) all of the protective relays, 3) all indicators and annunciators, and 4) the remaining auxiliary equipment.
Why battery bank is used in substation
As long as the battery is kept charged, it can provide power continuously. Because batteries can hold electrical energy, they are a suitable option for a reinforcement power source. A substation contains a number of control circuits that are kept in the On state to operate switchgears, circuit breakers, isolators, and transfers.
