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.

    That is a bit hit and miss, as the video says that about a third of utilities can NOT be detected using the Cat and Genny. I don't like those odds at all.

    Presumably the likes of gas and water in plastic pipes (without a metallic marker tape) - which won't have much of an electromagnetic influence. Cables in steel conduit should be much easier to detect.

    Also, why do you need to wear a safety hat in an open field away from all buildings?

    Ah but they're archeologists - there's probably Tony Robinson's helicoper or drone to wory about, or spoil being flung all over the place by JCBs, or camera crews swinging all sorts of things around on long poles, or dodgy experiments with iron age technology done by people with no idea of common sense mechanics or range rovers driven by people not quite looking where they're going  (or maybe I've been watching too much time team…)
