The main theme of this project is to find the faults that was occurring in the three phase transmission lines with the help of arduino and displaying the same on the LCD screen.
This project develop an automatic tripping mechanism for the three phase supply system. The project output reset automatically after a brief interruption in the event temporary fault while it remains in tripped condition in case of permanent fault. The major advantage of the project is, it is not only save the appliance but it will also show the type of fault that has been occurred in the system so it will be easy for the operator to solve the problem easily. It will also check whether the fault is permanent or temporary and displays the same on the LCD.
