IoT based Monitoring and Control of Faults in Power Distribution Transformers

Abstract

Protection of the power system is an important aspect to protect electrical components against the faults to increase their lifetime, postpone unwanted replacement cost of damaged ones and assure continuity of supply to serve the growing demand. This work's prime objective is to develop an IoT (Internet of Things) based system that can be used to protect the transformer by monitoring and controlling the operating parameters, i.e., current value, oil level, etc., and reports that same. This system is so designed that it can sense the parameters beyond the standard preset level and alerts about the condition to isolate the transformer from the distribution line. This process ensures the safety of the transformer against any abnormal conditions. Therefore, this work presents the development of online monitoring and control of faults in a transformer and alerts the same. This IoT system is located at the transformer base, and considered parameters are monitored regularly, then transmitted to a centralized web server. Thus, the data are utilized to know the transformer condition on a real-time basis and are stored within a server database for future analysis purposes.
