The main purpose of these system is to provide the protection from overvoltage and undervoltage in system. Voltage fluctuations can severely impact electrical equipment, making it critical to develop a system that can detect and respond to unsafe voltage levels in power system. This project is designed to safeguard electrical equipment from harmful voltage fluctuations, the system continuously monitors voltage levels, disconnecting the load when values exceed safe limits. The Arduino processes real-time voltage data and displays it on the LCD, activating a relay to cut off power if needed. By leveraging the capabilities of the Arduino Uno, the system achieves high reliability and flexibility while remaining cost-effective. This low-cost system demonstrates reliable protection for residential and industrial applications, enhancing safety for sensitive devices. The research aims to contribute a viable solution for enhanced load protection in both industrial and residential setting.

1. INTRODUCTION Voltage stability is essential for the safe operation of electrical devices, yet fluctuations such as overvoltage and undervoltage are common due to grid issues, load variations, and environmental factors. Such voltage fluctuations can lead to irreversible damage, reduced performance, and even operational hazards in sensitive equipment. Overvoltage and undervoltage conditions can result in excessive strain on electrical appliances, lead to irreversible damage, inefficiencies, and even operational hazards in sensitive equipment, safety risks like overheating or fires. While industrial-grade voltage protection systems exist, they are often complex and expensive, making them impractical for average household use. To minimize this issues we made a simple, cost-effective overvoltage and undervoltage protection
