transmitter's ground is connected to another access point in the target pipeline through a
long wire. This eliminates the need for grounding to form a complete circuit. The long
pipeline should be far from the possible direction ofthe target pipeline.

5.Some Problems in Power Cable Detection
Before applying the transmitter signal, it is necessary to disassemble the common
connector on the cable so that the target cable can be traced. If you want to track all
the cables starting from the transfer box, you can make the transmitter work in
inductive connection mode, place it on one side of the transfer box and align it with the
cable to be tracked.
In order for the transmitter signal to travel a sufficient distance, it is necessary to
remove the ground connectionof the cable.
Power cables that have a ring in the ground will weaken the response on the
cable path. At this point, the search range should be increased and return to the point
before the response change. The receiver will be able to determine all the wire loops
except the minimum in the cable.
Most cable connectors will show a peak pulse signal at the receiver. The
experience of on-site detection and understanding of the actual situation can determine
whether the peak pulse signalindicates a junction box.
