IRJET - Monitoring and Protection of Distribution Transformer using GSM Module

This document presents a monitoring and protection system for distribution transformers using GSM and GPS technology. The system continuously monitors transformer parameters like load current, voltage, oil level, and ambient temperature using sensors. If any abnormalities are detected, an alert message with the parameter values and location is sent to the monitoring center via GSM and GPS modules. This allows problems to be identified early to prevent failures and save costs compared to manual monitoring. The system includes components like a power supply, microcontroller, LCD display, fault indicator, MAX232, relay, and GSM modem to monitor and send alerts on transformer faults.
