Cable break location

[NoSparks]

Breaks in cables often occur. Has anybody any good ideas how to locate the break point?

eg we have an office block in which the cpc is broken. Apart from the obvious ( looking at the fittings), how can we best locate the fault? Is there any method of measuring the length of wire that is intact?

I'm no Electrician but I do a lot of work on cars. If I thought there was a break in a particular wire then I would first try to pin point the wire causing the issue and then do a continuity test on it.

It would probably take a number of tests at different points along that wire in order to pin point the break.

Use a T.D.R.

I dont think many people would have access to a Time-Domain Reflectometer.

Use a T.D.R.

Like this? Time Domain Reflectometer, ECAD, Cable Testing, PCI-3140R, 1502, 1503 TDR

A TDR, that looks exactly like what I need but it also looks expensive. I'll investigate further. Thanks for the suggestion.

If you google TDR hire you will find firms who hire them out.

O.T.D.R. that'll be ! Used many times installing fibre on old job ;-)
