Power Factor Improvement Calculator

The Power Factor Improvement Calculator for 3-Phase Systems is a user-friendly tool designed to help optimize electrical systems by calculating the required capacitor rating to improve power factor. Users simply input the system’s power (KW), present power factor (PF1), desired power factor (PF2), and frequency (50 Hz/60 Hz), and the tool instantly computes the KVAR rating of the capacitor needed and the corresponding capacitor rating in microfarads for a delta connection. Improving power factor reduces energy losses, lowers electricity costs, and minimizes carbon emissions by enhancing system efficiency. The formula used is KVAR Rating = KW × (tan(cos⁻¹(PF1)) – tan(cos⁻¹(PF2)), which determines the reactive power required for correction. This tool is ideal for engineers and technicians aiming to achieve energy efficiency and sustainability in electrical systems.
