Abstract:
T-WATCH (Transformer Winding Alert Temperature Control Hub) Is An IoT-based Transformer Monitoring And Control System Designed To Improve Reliability, Safety, And Operational Efficiency. The System Uses A NodeMCU ESP32s To Continuously Monitor Key Transformer Parameters Such As Temperature, Voltage, And Current Through Dedicated Sensors. Real-time Processing Enables Power Calculation, Fault De-tection, And Automatic Relay Tripping When Predefined Thresholds Are Exceeded, Ensuring Fail-safe Operation. The System Employs MQTT-based Bidirectional Communication Through HiveMQ Cloud, Enabling Real-time Data Transmission And Remote Control Functions Such As Transformer Trip And Reset. A Cross-platform React Native Application Provides Live Monitoring, Data Visual-ization, Diagnostic Analysis, And System Health Assessment. The Application Also Supports Offline Data Storage, Cloud Synchroniza-tion Via Firebase, And PDF Report Generation For Maintenance Purposes. By Integrating Real-time Sensing, Cloud Communication, And Intelligent Diagnostics, T-WATCH Offers A Scalable And Cost-effective Solution For Modern Transformer Management. The System Enhances Fault Detection, Enables Predictive Maintenance, And Contributes To Improved Asset Performance And Lifecycle Management.
