Single Phase Differential Transformer Protection Using Arduino

Transformers are the important parts in the power system. So, development of better protection device for Transformers is essential. Differential relay technique can be employed to protect the Transformers. In this paper we have used differential relay mechanism with Arduino. By programming in the Arduino the protection of transformers can be done. The working of transformer is verified by Arduino every time. It senses the condition of transformer each and every second. If it founds any error then it sends commands to the circuit breakers to trip the main potential transformer. So it is the efficient and best method to protect the transformers under abnormal conditions.
