Abstract: Automatic power line fault detection is a device that detects, identifies and locates the fault present in the power distribution line caused by various natural or manmade forces. This project mainly focuses on the section of power line that connects the transformer with customers. These faults are directly affects the customers so that it must be found out and rectified as fast as possible. This is done by placing individual units on certain points of the power line which consists of set of voltage and current sensors. Using sensor values, the system checks whether there is any fault is present on the line or not.
