The objective of this project is to determine the distance of  underground cable fault from the base station in kilometers and displayed over the internet. Underground cable system is a common practice followed in major urban areas.

While a fault occurs for some reason, at that time the repairing process related to that particular cable is difficult due to exact unknown location of the fault in the cable.

Proposed system is used to find out the exact location of the fault and to send data in graphical format to a dedicated website together with on board LCD display using  a  GSM module.

The project uses the standard theory of Ohms law, i.e., when a low DC voltage is applied at the feeder end through a series resistor (Cable lines), then the current would vary depending upon the location of the fault in the cable as the resistance is proportional to the distance.

In case there is a short circuit (Line to Ground), the voltage across series resistors changes according to the resistance that changes with distance .This is then fed to an ADC to develop precise digital data which the programmed microcontroller of the 8051 family displays in kilometers.

The project is assembled with a set of resistors representing the cable length in km and the fault creation is made by a set of switches at every known km to cross check the accuracy of the same.

The fault occurring at a particular distance, the respective phase along with the distance is displayed on the LCD. The same information is also sent to a dedicated website over internet activated SIM with GSM, interfaced to the microcontroller.

Furthermore, this project can be enhanced by using capacitor in an AC circuit to measure the impedance which can even locate the open circuited cable, unlike the short circuited fault that uses only resistors in DC circuit as followed in the above proposed project.

I was searching about projects
i purchased 1st time through online so that's why i have chosen edgefx
yeah i received everything on right time
Niranjan, anytime i called him he responded very well and he gave me satisfactory service
I’m concerned about the service he helped me a lot in our project that's enough
I told my friends already

I was searching underground cable fault in google then i found edgefx in google
I have decided to buy project from edgefx because i found the title in the website then i have decided to buy projec from edgefx. I like the audio- visuals of the project.
the kit was delivered on time with right components.
i called a person the number which is in the website he has helped me in purchasing the project.

I searched for the words like Display of Underground Cable Fault Distance over Internet find in Edgefx in Google
I found my project Title so decided to buy that project
The kit got delivered to me on time with all the right components.

Will this system work if only one side of the wire is available?
