Distribution Transformer Monitoring and Controlling Using GSM Module

Abstract

This project is about design and implementation of a system to monitor and record key parameters of a distribution transformer like load currents, load voltage, oil level and ambient temperature. The idea of on-line monitoring system integrates a global service mobile (GSM) Modem, with AVR microcontroller and different sensors. It is installed at the distribution transformer site and the above parameters are recorded using AVR microcontroller, obtained parameters are processed and recorded in the system memory. If any abnormality or an emergency situation occurs the system sends SMS (short message service) messages to the mobile phones containing information about the abnormality according to some predefined instructions programmed in the controller. This system will help the transformers to operate smoothly and identify problems before any catastrophic failure.
