Automatic Bank Capacitor Design for Improving Power Factors in Arduino Uno-Based Three-Phase Induction Motors: A Case Study of USU Electrical Engineering Transmission and Distribution Lab

Introduction

Induction motors are the backbone of modern industrial electric propulsion systems, offering several advantages such as relatively low prices, simple designs, good durability, ease of production, cage motor design without brush, and low weight/power ratio. However, induction motors have a significant weakness - high reactive power consumption. This can lead to a decrease in voltage, equipment damage, and decreased power factors, ultimately resulting in a decrease in voltage and increased loss in the transmission channel. To overcome this problem, this research designs a system of improving power factors automatically using a capacitor bank, which will inject reactive power to the source of excitation, thereby increasing the power factor.

The Importance of Power Factors

Low power factors can cause various problems, such as:

  • Voltage reduction: High reactive power can cause a decrease in voltage in the electricity network, disrupting the performance of electrical equipment.
