Underground Cable Tracing.

Zoomup

An P.V.C./P.V.C.  cable is run in steel conduit underground from a farm barn to another location. It may run underground to some nearby concrete slabs previously used as a base for wooden sheds, or it may run for about 80 metres to some distant  derelict outbuildings.

I am not too familiar with all of the types of underground cable tracers available.

Which would be the best type of cable tracer to use to determine its run? There may be other buried metal to confuse some tracers. Will a signal injected into the cable be able to be detected by a cable tracer as the cable in inside steel conduit?

The cable is currently dead.

Thanks,

Z.

    I used to go to the Local IET Group meetings, there was a really good one at the Mount Pleasant Hotel in Malvern.

    The speaker was a guy in his nineties who worked on the team in the early days of research into radar down at the bottom of the road in Malvern. The room was absolutely packed it was standing room only for latecomers, I had managed to get a seat in the back row and was sitting by a couple of University Professors. 

    The speaker was explaining the vast distances they were bouncing signals across, down to South America and back again, then about how they were measuring to signals reflected off aircraft as they flew past the BBC Droitwich aerials.

    I raised my hand and asked a question “Presumably these planes were made from wood and canvas, so what was reflecting the signal?”.

    He laughed and said the propellers were wood as well! The reflected signal was from the engine, fixings holding the wooden frame together, other ironmongery such as door hinges, control cables and of course bombs in the bomb bays of bombers, making bombers easier to find then fighters.

    Honestly, in the early days of they were trying aircraft by locating its engine and assorted metal fittings from many miles away, the guy sat next to me passed comment that even from a few hundred miles away an engine is a surprisingly large target when it’s the only thing in the sky.
