Abstract: A system is designed to monitor the Transformer throughout its operation, using arduino. Also a protection scheme is employed with the help of the relay circuit. An LCD is associated with arduino which continuously displays the transformer’s parameters. Values of parameters like current, temperature, voltage and oil level are pre-set in the system already, when the values are exceeded buzzer sets the alarm to indicate that a fault has occurred and simultaneously the values are updated over Wi Fi. Further if the fault is severe the relay circuit will operate and the system will shut down. Different circuits like current sensor, voltage sensor, ultra-sonic sensors, lm35, etc. are used to monitor the parameters and pass the data to arduino. After receiving the data these values are compared with the predetermined values and actions are taken accordingly. All the data of the parameters can be stored and used for further analysis with the help of Wi Fi module. Henceforth, the monitoring as well as protection of the transformer is done smartly.
