Description
⚙️ Project Overview
The Fully Automatic Power Factor Compensation (APFC) system by FluxPrime is designed to improve power quality in single-phase industrial loads. The project automatically maintains near-unity power factor using an Arduino microcontroller, current transformer (CT), and relay-controlled capacitor bank.
It ensures efficient energy usage, reduces line losses, and prevents power factor penalties, making it a highly relevant and practical project for students and industries.
🧠 Working Principle
-
The CT sensor measures the current drawn by the load.
-
The Arduino calculates the phase difference between current and voltage.
-
If the system detects a lagging power factor, it activates relays to connect capacitors.
-
The capacitors compensate for the reactive component, bringing the power factor closer to unity.
-
The system displays real-time power factor on an LCD or LED display.
