SUMMARY
Power Factor Correction (PFC) involves understanding KVARs (Kilovolt-Amperes Reactive), which represent reactive power in electrical systems, particularly in relation to non-resistive devices like motors and solenoids. KVARs contribute to inefficiencies and increased costs, as they indicate excess current supplied by electricity retailers without performing productive work. The power triangle illustrates the relationship between watts, KVA, and KVAR, with a power factor (PF) calculated by dividing watts by KVA. For example, a motor rated at 10 kilowatts using 13 KVA results in a power factor of 0.77.
