AUTOMATIC POWER FACTOR CORRECTION WITH ALL POWER MEASUREMENTS OVER LORA WIRELESS COMMUNICATION

Automatic power factor corrector is designed to improve power factor automatically whenever power factor falls below a certain level. Efficient generation of power at present is crucial as wastage of power is a global concern. As we know, the demand for electrical energy is increasing day by day. Power factor measures a system’s power efficiency and is an important aspect in improving the quality of supply. This paper presents an embedded system for automatic power factor correction with comprehensive power measurements via LoRa wireless communication. It comprises two Arduino Uno-based modules for both transmission and reception., In this system utilising PT and CT sensors for accurate power measurements. Data exchange is achieved through two LoRaWAN modules over a 100-metre range, with real-time power factor and correction data displayed on an LCD at the receiver end. The heart of the system is a capacitor bank equipped with relay switching, intelligently optimising the power factor. A half HP motor serves as the load, exemplifying the practical benefits of efficient power factor correction in electrical systems, ultimately enhancing energy efficiency and reducing costs.
