Cable fault locator for underground PSTN cables

[efarook]

Hello everybody,

I want to build a cable fault locator for my own use. I know there are some ready made stuffs out there in the market, but I want to build my own version.

This fault locator will be able to monitor and detect open and short cable faults. This is simple, I will be able to design a circuit for this.

But what I could not get after a long search on the net is that how to locate the fault. I read about TDR (Time Domain Reflectometry) but this is not so handy for my field use.

Can anyone suggest any other simpler techniques to find the location of the fault in the cable?

Thanks in advance.

TDR is just about the only way of locating a fault in an underground cable.
