Sensor Fusion-Based Real-Time Monitoring and Arc Recording System for Distribution Panel

This study proposes a sensor-fusion-based real-time monitoring system designed to detect early abnormal signs inside distribution panel and automatically record video when arc is detected. Unlike conventional systems that rely on single sensors or manual inspections, the proposed system integrates temperature, humidity, vibration, and illuminance sensors to continuously monitor internal conditions. When thresholds are exceeded, it triggers alerts and saves related video data. Experimental results confirm its effectiveness in fast and accurate detection, enhancing monitoring reliability. This system offers foundational technology for improving predictive maintenance and accident response in electrical facilities.
