Power Factor Correction: What is it? (Formula, Circuit & Capacitor Banks)
Capacitor Banks: Capacitor banks, which can be connected in delta or star configurations, are used to improve the power factor in three-phase systems. Active Power Factor Correction : This advanced method uses high-frequency switching elements to efficiently control the power factor in circuits with high power demands.

Troubleshooting Power Factor Correction Capacitors | Fluke
Capacitor banks normally provide years of service, but they need to be inspected on a regular basis to make sure they are working properly. Problems such as loose connections, blown fuses or failing capacitors can reduce the amount of power correction available and, in extreme cases, even cause a total system failure or a fire.
