?What is the primary function of a PFI (Power Factor Improvement) panel in an electrical system

The primary function of a PFI (Power Factor Improvement) panel in an electrical system is to improve the power factor by automatically adding or removing capacitor banks as needed. By doing so, the PFI panel helps to reduce the reactive power component, thus improving the efficiency of the power system. This results in lower electricity consumption, reduced demand charges, and minimized losses in the electrical distribution network. Improved power factor also enhances the capacity of the electrical system and prolongs the lifespan of electrical equipment.

?How do capacitors in a PFI panel contribute to power factor correction

Capacitors in a PFI panel contribute to power factor correction by providing leading reactive power to counteract the lagging reactive power typically caused by inductive loads such as motors and transformers. When capacitors are connected to the electrical system, they generate a leading current that offsets the lagging current, thereby reducing the overall reactive power demand. This correction results in a power factor closer to unity, improving the efficiency of the power system, reducing energy losses, and lowering electricity bills by decreasing the demand charges from utility companies.
