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.

    Years ago I tried out a metal detector, I then dug a hole and exposed some old corrugated sheets my dad had put over the top of a soak away, nothing is infallible.

    Do you accept that you can magnetise a screwdriver blade or a metal rod by hitting it with a hammer or banging it on something, like the cutlery I mentioned above?

    If you do, do you then accept that other metal objects can take on a magnetic field or be influenced by the magnetic  field of the earth? The answer to that has to be yes or you will be refusing to accept compasses work and cannot be used for navigation.

    So could the metal conduit have become partially magnetic or affect the natural magnetic field?

    I promise the next post will Wiring Regulations related.
