PROJECT DESCRIPTION

The objective of this project is to determine the distance of  underground cable fault from the base station in kilometers. 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 an SMS with details to a remote mobile phone using 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 resistane 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 the concerned authority mobile phone over 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 searched for the words like Underground Cable Fault Distance Conveyed over GSM to find Edgefx in Google.
I found my project Title so decided to buy that project from Edgefx.
The kit got delivered to me on time with all the right components.
