This paper to develop an automatic tripping mechanism for the three phase supply system. The project output resets automatically after a brief interruption in the event temporary fault while it remain remains in tripped condition in case of permanent fault. The electrical substation which supply the power to the consumers, have failures due to some faults which can be temporary or permanent. These faults lead to substantial damage to the power system equipment. In India it is common, the faults might be LG (Line to Ground), LL (Line to Line), 3L (Three lines) in the supply systems and these faults in three phase supply system can affect the power system. To overcome this problem a system is built, which can sense these faults and automatically disconnects the supply to avoid large scale damage to the control gears in the grid sub-stations. This project is designed to understand about the basic operation of the relay and what are all the advanced techniques that are being used by the people to ensure the safe operation of the electrical appliance. The circuit will isolate the load from the supply if any power fluctuation occurred. The major advantage of the project is, it not only save the appliance but it will also show the type of the fault that has been occurred in the system so that it will be easy for the operator to solve the problem easily. It will also check whether the fault is a permanent or a temporary fault. If the fault is temporary fault then the supply will be restored after a predefined time of 5-10 seconds otherwise a permanent trip signal is given to the relays.

Keywords- Three phase fault, tripping mechanism, microcontroller, and ADC.
