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
