Which is the more accurate technique for the fault location calculation.
Dear Rajeev,
For underground cable faults location, REFLECTOMETRY seems to be a good tool but should be associated with signal processing techniques. The attached paper is an illustration of the way to address this issue.

Rajeev,
Are you talking of small distribution cable routes, or EHV stuff like underwater tie lines etc ?

I agree with Sanjjoy; it depends on what are your specifications.
However, you can look into RCDs (Residual Current Devices) they trip as soon as the current on phase and neutral differs by 30mA, 100mA, 200mA, 300mA etc.
Or you can also do your own testing. Measure the current entering every cable and compare it with the current leaving the same cable.
But like we said; it depends on your requirements, specifications, infrastructure available etc.
Thumpers are the industry standard device for fault location

Dear Sanjay,
I am talking about small distribution cables only.

Rajeev,
In that case I suggest you take a look at the book by Horowitz & Phadke. There are many cross references in it that can be your starting point.
Cheers !

Any modern numerical relay ABB, SIEMENS, GE, AREVA have fault locator module which can detect the location of fault..
