Transformers are simple devices that transfer electricity by changing the induced current in one circuit to another. Step-ups and step-downs of current or voltage are frequently used to convert the induced current. This application principally concentrates on the three phase transformer which are utilized in between electric poles & power transformers. The basic features, such as temperature, voltage, and current, are controlled in real time. These characteristics are necessary for efficient power transfer and an industrial transformer's extended lifespan. The Arduino controller and sensor, which regularly monitor the transformer's voltage, current, and temperature, are used to complete the monitoring and control process. There are other ways to maintain transformers, however this project uses an Arduino Uno Controller to monitor and manage the transformer in real time, replacing large computers with an embedded system. Real-time control and monitoring of the transformer's temperature range and current voltage exceeded are made possible by the design, which senses the transformer's characteristics and sends the data to the processor on a regular basis. The IOT module on Things Speak will be used to update all data via a web server.
