This is a simple project which can be used to locate exact distance of fault in electrical lines and can show to base station in kilometers. This approach is very useful for urban are. at the time of repairing worker can remove the fault from exact position, this project overcomes the excess and non directional work.
This is a microcontroller based project and it works on the basis of resistance of cable. When any error is occurred microcontroller detect the exact distance of fault from base station. This project is based on ohms low, when low voltage is applied to cable value of current is varied according distance of fault, this value is read out by microcontroller.
