GSM Based Monitoring and Protection of Distribution Transformer

Abstract

The traditional electricity grid system has proved to be incompetent with the growing energy needs. In order to provide reliable operations and uninterrupted electric power supply to consumers connected in the electricity grid system, there is a strong need to upgrade the traditional electricity grid with the modern generation of grids that are equipped with communication technologies and vast deployment of sensors. Since the distribution transformers have an essential role in delivering electricity to the consumers, distribution transformer must be operated under rated conditions. In this regard, the reliable operation and cost savings can be made by monitoring the distribution transformer before any fault occurrence. This project provides the design and implementation of hardware to monitor the useful parameters such as ambient temperature, load currents, over voltage and oil level of the distribution transformer. The monitored data obtained from the remotely located distribution transformers is send to the mobile operator using GSM technology. If any abnormalities are investigated in the received parameters of distribution transformers, then SMS and call is made to the mobile engineer to take necessary action so that uninterrupted power supply is ensured to electricity consumers.
