The project is intended to detect the location of fault in underground cable lines from the base station to exact location in kilometers using an Arduino micro controller kit in the urban areas. This system uses an Arduino micro controller kit and a rectified power supply. Here the current sensing circuits made with a combination of resistors are interfaced to Arduino micro controller kit to help of the internal ADC device for providing digital data to the microcontroller representing the cable length in kilometers.
A 16x2 LCD display connected to the microcontroller to display the information. In case of open circuit the length of cable varies based on the location of cable cut (open). As the cable is open parallel wire capacitance gets reduced , which is then fed to an ADC to develop precise digital data to a programmed Arduino micro controller kit that further displays exact fault location from base station in kilometres.
