Abstract: Since, “prevention is better than cure”, transformers monitoring system is essential to optimally utilize and hence increase life time of these distributed equipments in the power grid. In this study, a new approach is applied to do that job by integrating three technologies: General packet radio services (GSM/GPRS), internet of things and publish/subscribe messaging paradigm. Practically, researcher found that publish/subscribe messaging model fits several requirements of IoT as it allows data to be sent based on interests rather than agent addresses and releases the topology of the network. In addition, GPRS services increased mobility and reliability of the system. However, the deigned system implemented three parts: Transformer Agent (TA) which instills at transformer site to collect operationkey parameters, dweetplatform as broker server which realizes connection between publisher and subscriber and finally, graphical user which interfaces program to display information coming from remote TAs. While, the designed system is installed and tested at the laboratory environment, it gave freedom to select different sensors package according to actual needing. The system gave good results as early warning and it has high interoperability and scalability with lowest cost for deploying.
