Abstract: Three-phase power systems are widely used in industrial and commercial applications due to their efficiency and reliability. However, failures such as phase loss, voltage imbalance, and phase interruption can cause serious damage to electrical equipment. This paper presents the design and implementation of a Three Phase Failure Detector using an Arduino Nano. The system continuously monitors the voltage of each phase using voltage sensor modules. When a fault condition is detected, the system provides visual and audible alerts using an OLED display, LED indicators, and an active buzzer. The proposed system is compact, low- cost, and suitable for real-time monitoring applications.
