Project Model No: 164 ABSTRACT PRECISE KILLOMETER CALCULATION BY UNDERGROUND CABLE FAULT DETECTOR The project uses the simple concept of OHMs law where a low DC voltage is applied at the feeder end through a series resistor. The current would vary depending upon the length of fault of the cable in case there is a short circuit of LL or 3L or LG etc. The series resistor voltage drop changes accordingly which is then fed to an ADC to develop precise digital data which the programmed microcontroller
