5.2.3
Cable breakdown location
Keep in mind that the ferromagnetic shield over the cable conductor may reduce the detected sig-
nal strength so the search shall be made at maximum possible current.
5.2.3.1 Finding of short-circuited conductors
shows the diagram of tracing the short-circuited cables. The Receiver LKO shall be
brought along the target utility, and the signal strength shall be controlled on the peak scale. The sig-
nal strength may change before the shorted area depending to the cable lay pitch. The signal fluctua-
tion stops behind the short-circuited area, and signal strength may drop (case 1) or rise (case 2). In
the first case, the dead short takes place, when only the cable conductors are shorted. In the second
case, the cable conductors are shorted to each other and to the shield.

5.2.3.2
Location of shorted conductor-shield positions
The layout of location of conductor-shield shorted area is shown in
strength may change before the shorted area depending to the cable lay pitch. The signal fluctuation
behind the short-circuited area remains the same, and signal strength rise abruptly.
