How does a capacitor work?
On power systems, capacitors do not store their energy very long—just one-half cycle. Each half cycle, a capacitor charges up and then discharges its stored energy back into the system. The net real power transfer is zero. Just when a motor with low power factor needs power from the system, the capacitor is there to provide it.
How can a capacitor improve the power factor of an electrical installation?
It’s quite simple. By installing capacitors or capacitor banks. Improving the power factor of an electrical installation consists of giving it the means to “produce” a certain proportion of the reactive energy it consumes itself.
Why do generators use capacitors?
Capacitors and reactive loads exchange this reactive power back and forth. This benefits the system because that reactive power (and extra current) does not have to be transmitted from the generators all the way through many transformers and many kilometers of lines. The capacitors can provide the reactive power locally.
