Design and Implementation of Distribution Transformer Monitoring System Using GSM Technology

This research paper presents designing and implementing a distribution transformer monitoring system to protect transformers from faults. In many developing countries, existing monitoring systems rely heavily on manual intervention, making it difficult to predict potential faults promptly. To address this, an Arduino microcontroller, sensors, and GSM technology were utilized in this research work to develop a system that automatically monitors and protects distribution transformers. The proposed system monitors key transformer parameters, such as low, high, and open circuits. The design was developed using Proteus software and C++ programming, and the results were analyzed in Microsoft Excel. The system detects transformer faults and automatically sends SMS alerts via the integrated GSM module. Validation was carried out through simulation and experimental testing of the prototype, and the results closely matched the design expectations, confirming the reliability of the proposed system.
