An APFC (Automatic Power Factor Correction) Panel is an electrical device designed to improve the power factor in electrical systems by automatically controlling and managing the power factor correction capacitors. The panel helps maintain an optimal power factor, reducing energy losses, improving energy efficiency, and lowering electricity costs by minimizing penalties imposed by utility companies for low power factor.

  • Power Factor Monitoring:

    • Real-Time Monitoring: The APFC panel continuously monitors the power factor of the electrical system, typically using power factor meters or controllers.
    • Automatic Adjustment: Based on the monitored data, the panel automatically switches capacitor banks on or off to maintain the desired power factor level.
  • Capacitor Banks:

    • Multiple Capacitor Steps: The panel is equipped with several capacitor banks, each representing a specific reactive power value. These capacitors are switched in or out of the circuit depending on the required power factor correction.
    • Automatic Switching: The panel uses contactors or solid-state relays to switch capacitor banks on or off as needed, ensuring that the power factor remains within the optimal range.
