Design of a Distribution Transformer Monitoring System using Global System Mobile Technology

Abstract

Distribution transformer is considered one the most important element in the power distribution system as it works to reduce the high voltage to the consumption voltage. To achieve maximum efficiency of these transformers and to ensure stability of the power distribution system, their operational conditions must be quite appropriate which led to perform their task efficiently throughout their life time. This research aims to design a monitoring system for the distribution transformer by installing different sensors on it. These sensors monitor the level of transformer oil, temperature, voltage range and a magnetic sensor that monitors the transformer when it trips and gets out of service. This monitoring system works by observing these sensors and send its readings in case of exceeding the allowable limits by using SMS to a mobile phone via GSM technology. This system is designed in Proteus program using Atmega32 microcontroller and programmed by Bascom language.
