Automatic Power Factor Panel (APFC) service involves the maintenance, inspection, and optimization of panels designed to improve power factor automatically in electrical systems. These panels use capacitor banks and controllers to reduce reactive power, enhancing energy efficiency and lowering electricity bills. Regular service ensures that all components, including contactors, capacitors, and relays, function correctly and respond accurately to load changes. Technicians check for loose connections, overheating, and faulty parts. Proper APFC panel servicing extends equipment life, prevents penalties from utility companies, and ensures stable voltage levels. It is essential for industries with fluctuating loads and high reactive power demand.
