The present scenario is very complicated over finding the faults and repairing it, so new technology is designed which will automatically find the fault over the transmission line, this will help us to provide with maintenance. This technology will also save time and money over maintenance. Transmission of power generated from power plants to consumers has been vastly improved and expanded to every corner of the world during the last two decades. The recent development of series compensation in power systems can greatly increase power transfer capability, damp power oscillations (if carefully designed) and improve transient stability. However, fault clearing and finding in such transmission networks are considered to be one of the most important tasks for manufactures, operators, and maintenance engineers. The transmission lines are widely used in our day-by-day life to communicate or to transfer data. Some examples of transmission lines are telephone lines and cable lines. The problems arising due to physical or atmospheric conditions in this transmission line. To find the problem according to the faulty line at a particular point our circuit is necessary. We know that time is money. In the future, we don't have time to find fault manually. So, with the help of this project, we can find fault in transmission line in control room easily. Due to this we can find fault and repair quickly and save time. This project reduces human efforts because this prototype is having great scope in the future.
