Power factor correction capacitor

A Power factor correction capacitor (PFC capacitor) is an electronic component employed in electrical systems to improve the power factor. In situations where inductive loads, like motors and transformers, introduce reactive power and cause a phase shift between voltage and current, power factor correction capacitors are strategically utilized. These capacitors introduce capacitive reactive power to counteract the effects of reactive power, aligning voltage and current waveforms. By doing so, they enhance the power factor, contributing to increased energy efficiency, reduced line losses, and improved stability in the electrical system. Power factor correction capacitors are particularly valuable in environments with numerous inductive loads, optimizing the overall performance of the electrical system.
