Abstract
Power factor correction is an essential requirement in industrial power distribution. A low PF leads to increased current draw, causing excessive heating, higher power losses, and inefficiency in the electrical system. To counter this, industries use capacitor banks to improve PF, but manual correction systems often suffer from inefficiencies. . Problems of power quality in industrial plants are growing due to the increasing number of rectifier controlled motors and the overall increase of harmonics and inter harmonics 1. Our approach focuses on designing an automated power factor correction system for 3-phase loads using an Arduino Mega. Capacitors generally are the most economical means to improve power factors. Power factor correction is the term given to a technology that has been used since the turn of the 20th century to restore the power factor to as close to unity as is economically stable. 3 The system continuously monitors PF using CTs and PTs, detecting drops below 0.93 due to Inductive loads. When required, it switches capacitors in Parallel to the load, restoring PF to 0.98 dynamically. This automated approach ensures improved power utilization, reduces penalties imposed by energy providers, and enhances overall system efficiency. The project involves testing with resistive and inductive loads. The system integrates sensors for real-time monitoring, enabling quick capacitor switching decisions based on predefined.
