The objective of this project is to determine the distance of underground cable fault from base station in kilometers. The underground cable system is a common practice followed in many urban areas.

While a fault occurs for some reason, at that time the repairing process related to that particular cable is difficult due to not knowing the exact location of the cable fault. The proposed system is to find the exact location of the fault.

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

In case there is a short circuit (Line to Ground), the voltage across series resistors changes accordingly, which is then fed to an ADC to develop precise digital data which the programmed microcontroller of 8051 family would display in kilometers.

The project is assembled with a set of resistors representing cable length in KM’s and 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 and the respective phase is displayed on a LCD interfaced to the microcontroller.

Further 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 only using resistors in DC circuit as followed in the above proposed project.

Q & A
Q:  How is the underground cable fault detection done?
A:  Underground cable fault detection is done using cable voltage drop as an input and resistance at every kilometer is the consideration.
Q:  How is the fault detected?
A:  Cable length represented by a set of resistors is subjected to a current flow through a series resistor, the voltage drop of which is used in the programming through ADC to calculate the distance.
Q:  What are the types of fault created in this system?
A:  Three Line to Ground, three Line-to-Lines and line to line are the types of faults created in this system.
Q:  Which microcontroller is used in this project?
A:  A 40 pin microcontroller from 8051 family is used in this project.

I decided to buy a kit from Edgefx because last year i was taken the mini project from Edgefx. I like most about the kit is Audiovisuals.
