Abstract

In industrial power systems, maintaining an optimal power factor is essential for efficiency and cost- effectiveness. This project presents a 3-phase Power Factor Improvisor using an Arduino Mega, CTs (Current Transformers), and PTs (Potential Transformers). When the PF drops below 0.93 due to inductive loads like choke coils, capacitors from a capacitor bank are switched in parallel with the load to restore the PF to 0.98. The system continuously monitors PF and applies real-time corrections, improving energy efficiency and reducing penalties. A combination of resistive (100W bulbs) and inductive loads (tube lights with choke coils) is used for testing. The project provides an automated solution for industries, optimizing power usage and minimizing unnecessary energy wastage.
