Underground Cable Fault Distance Locator

They are any defect inconsistent insulation failure weakness of the cable and breaking of the conductor. This project uses the ohms law concept when a low voltage dc is applied to the feeder end through a series resistor then the current would differ based on the location of fault occurred in the cable in case is there any short circuit occurred from line to ground then the voltage across series resistor alters accordingly then it is fed to an. Pulse echo impulse current and decay method for all types of fault conditions.
