In the present work, the main objective is to find out the location of fault occurred in Underground cable of single phase AC line. The components used to find the fault in Underground cable are Current sensor, PIC Microcontroller, LCD, Relay, IOT. The current sensor is connected in series with the phase line of Underground cable. It works on the principle of Electro Magnetic Flux. The current sensor will monitor the voltage value of the phase line. The output of the current sensor is interfaced with the PIC Microcontroller. The LCD will display both input and output (voltage & current) value through the microcontroller. If any fault occurs in the phase line, the relay will trip the circuit by using PIC Microcontroller. The IOT intimate the user through PIC Microcontroller.

Keywords: PIC Microcontroller; Current sensor; Internet of things; Liquid crystal display; Power Relay.
