Distribution Transformer Monitoring for smart grid in India

This paper introduces the Distributed Transformer Monitoring System using Field Programmable Gate Array based technology integrated with wireless communication modules and its utilization for a smart grid. It consists of network of sensors and energy meters. The whole architecture and the hardware & software flow of the system have been explained. The real time data collected is a rich source of repository for data analysis and modelling, life of the transformer. The system is installed at the group of distribution transformer to test its performance in field. The developed approach effectively monitors the network of transformers operating state, dispatches the critical information, thus helps utility operator to keep transformer in service for long life. It is also has the advantages of significant cost savings and greater reliability. A number of smart actions and applications, such as smart metering, condition monitoring of transformer, load forecasting, power quality monitoring are came out of the system.
