An APFC Panel (Automatic Power Factor Correction Panel) automatically improves power factor by intelligently switching capacitor banks in steps based on real-time load conditions. The microprocessor-based or intelligent controller continuously measures reactive power using CT inputs and voltage sensing, and then switches the required kvar steps to maintain the desired target power factor. Detuned reactors can be incorporated to prevent resonance and safeguard capacitors in harmonic-rich networks, ensuring longer life and system stability. Built to IEC 61439 design practices and equipped with IEC 60947 compliant switchgear, these panels guarantee safe, reliable, and efficient operation. By maintaining an optimal power factor, APFC Panels significantly reduce demand charges, lower distribution losses, release transformer capacity, and improve overall voltage stability. These panels are widely used in industries, commercial complexes, hospitals, IT parks, malls, and infrastructure projects where reactive power control is critical.
