PF (Power Factor) Correction Panel

PF (Power Factor) Correction Panel is designed to improve the power factor of electrical installations by automatically controlling capacitor banks. It reduces reactive power demand, minimizes power losses and improves overall electrical system efficiency. The panel continuously monitors the load conditions and switches capacitor stages as required to maintain the desired power factor level.

By improving power factor, the panel helps in reducing electricity bills, avoiding utility penalties, and enhancing the life of electrical equipment. It ensures optimum utilization of transformer capacity and improves voltage stability in the system. PF Correction Panels are widely used in industries, commercial buildings and large electrical installations where inductive loads are present.

The PF Correction Panel is equipped with advanced microprocessor-based power factor controllers that ensure precise and reliable operation. It provides automatic as well as manual control options with necessary protection features such as overload, short circuit, over-voltage and harmonic filtering (optional). The panel is manufactured using high quality components and is suitable for continuous duty under varying load conditions, ensuring safe, stable and energy-efficient performance.
