Capacitor Banks: Its Applications in Substations & Working
As discussed earlier, capacitor banks are made by connecting numerous capacitors in series and parallel to create a storage device with a large capacity. This bank begins to charge as soon as it is attached to a power source, but because of the feedback-controlled mechanism, it will never overcharge because the controller will cut off the …
