It should be noted that:
the current level is substantially lower when it is generated in communication line by using
transmitter rather than direct galvanic connection;
transmitting signals are being routed to all adjacent current-conducting lines what may results
in wrong search directions;
the closer transmitter is located to communication line, the higher is the current level generat-
ed in communication line.
3.4.3.2 Inductive clamps
In case of access to communication line, for example, high voltage insulated live cable comes out,
it is reasonable to use
inductive clamps
. Due to better magnetic interaction with line circuit, they pro-
vide higher survey current generation and eliminate sending signal to adjacent communication lines.
Select the clamps to match the diameter of the clamped wire (see also
section 13.2
NOTE!
Do not connect conductive clamps to live bare conductors.
Current resistance shall be as low as possible in order to provide maximum current in the exam-
ined communication line circuit. It should be noted that the higher is operating frequency, the higher is
the level of the current generated in insulated and/or unearthed line when using clamps.
The clamps should be connected to the output sockets of the transmitter, while keeping the mark-
ings on the wires. The cable marked with the letter
E
with the grounding outlet of the transmitter
and the cable marked with the letter
H
with the load socket (p.13 Fig. 2). Grasp communication line
with clamp (
). On the transmitter panel press the
key to set the frequency from available.
