An Automatic Power Factor Correction (APFC) panel is an electrical device designed to maintain an optimal power factor in industrial, commercial, or residential settings. Power factor refers to the ratio of real power (active power) to apparent power in a system, and it’s crucial for maximizing the efficiency of electrical power distribution. Poor power factor causes energy wastage, high electricity bills, and potential damage to electrical equipment. An APFC panel works by automatically switching on or off capacitor banks to correct the power factor as per the load demand. It does this efficiently and dynamically, ensuring that the system always operates at or near unity power factor, thus optimizing power consumption.
