Underground Cable Tracing.

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.

    Have a look at the Wiring Matters article on TT earthing shows a suction method for excavation which I have seen done to great effect. Other than that careful hand digging with an insulated shovel.

    I had better not borrow an electrician's insulated shovel as some of the run is under thick concrete. I imagine that the owner of the shovel will not be best pleased when I use it.
