Abstract
The increasing use of inductive loads in domestic and industrial settings leads to reduced power system efficiency. This
project implements an automatic power factor correction system using an Arduino microcontroller (ATmega328p) to improve power
quality. The system measures power factor from single-phase voltage and current signals, calculates compensation requirements,
and switches capacitor banks using a 4-channel relay system. This approach enhances power system stability and efficiency
while reducing energy losses, making it suitable for household, domestic, and industrial applications.
The work demonstrates the feasibility of an IoT-assisted APFC teaching prototype while also identifying the need for calibrated voltage sensing, zero-crossing/phase-angle measurement, and controlled meter-based experiments before industrial deployment.

Currently, valve-type converters are widely used in industrial and household electrical equipment, leading to a decrease in power quality (PQ) in industrial and civil power supply systems. The generation of higher harmonic components of current and voltage leads to resonance,
neutral overload in three-phase networks, i...

Industrial loads dominated by induction motors tend to have a low power factor (cos φ), drawing excess reactive power from the PT PLN (Persero) grid. Under Ministerial Regulation ESDM No. 7 of 2024, industrial customers whose monthly average power factor is below 0.85 are charged for excess reactive power usage (kVArh)...
Background: The rising demand for electricity and increasing costs during peak hours require affordable and practical solutions to manage household energy consumption efficiently. Purpose: This study focuses on reducing electricity consumption and lowering utility bills during peak hours. The study developed a system t...

The increasing deployment of building-scale photovoltaic (PV) systems can influence power factor (PF) performance in electrical distribution networks, especially when reactive power demand is not properly compensated. Poor PF can increase apparent power demand, reduce distribution system efficiency, and expose consumer...
