⚡ Transformer Fault Detection using GSM Module

📌 Project Overview

The Transformer Fault Detection using GSM Module is an IoT-based monitoring system designed to detect critical faults in power distribution transformers and instantly notify the concerned authority via SMS alerts.

This system continuously monitors important transformer parameters such as temperature, voltage, current, and oil level. If any parameter exceeds the predefined safe threshold, an alert message is automatically sent using a GSM module.

This project enhances transformer safety, reduces downtime, and enables quick preventive action.
