Design And Hardware Implementation of Underground Cable Fault Detector

Abstract

The project works for detecting the fault location of The under ground cable line wires from the base point to the exact location point in kilometer standard using an Arduino Nano micro-controller kit. In the Urban areas, the Electrical cables are placed in undergrounds instead of overhead lines. It is difficult to find fault location for repairing of a specific cable wire. Our proposed system can find that location easily of the fault for processing the repairment of that particular cable. The simple Ohm’s Law concept is used here for doing the detection. The current sensor used here are the combination of resistors ,ADC and Arduino nano to give digital data to the micro-controller as to represent the cable length in kilometer standard. To show fault several switches are used. The relay switches are controlled by the relay driver. A 16*2 LCD display is connected to the micro-controller for displaying the information. In case of short circuit, the voltage across series resistors changes accordingly, which is then fed to an ADC (analog to digital converter) to develop precise digital data to the programmed Arduino micro-controller kit that further displays exact fault location point in kilometers from the base station. The buzzer rings when the fault occurs to warn the workers for repairment
