Multiple Choice

During a locate on a plastic pipeline, a sudden loss of signal most likely indicates what?

Explanation:
A sudden loss of signal during a locate on a plastic pipeline almost always means the tracer wire that carries the locating signal has been damaged or broken. Plastic pipe itself doesn’t conduct the locating signal, so the receiver relies on this tracer wire. If the wire is nicked, crushed, severed, or poorly connected, the energized path is interrupted and the receiver can no longer detect the signal, causing an abrupt drop. The other possibilities don’t fit this situation: a ground fault is a different electrical issue that wouldn’t explain an abrupt, complete loss of the locate signal along a plastic line; depth measurement doubling is a measurement error rather than a path interruption; and signals don’t magically improve without a change in the electrical path. If this happens, check continuity along the tracer wire, inspect for damage along the route, and repair or replace the damaged section.

    Decent resource so far for NGA 21. Some explanations are helpful, others skim the surface, and I wish the randomization covered more edge cases. Still, it’s good for drill and I can see my confidence slowly rising, especially with the flash cards and quick checks between chapters.
