Cable Locating System
The INTERSELECT NLT is used for the absolute correct identification
of power network assets by encoding a highly unique ID sequence.
Its main purpose is to increase safety by avoiding wrong cable line
selection and cable cuts during maintenance. The identification
works on most types of cable. Consisting of a paired transmitter and
receiver, the NT system injects a unique unipolar DC impulse
sequence remotely.
This ID sequence is genuinely different from line frequencies and
allows positive selection based on five evaluated parameters.
Additional applications include tracking of open cables in conduits
and continuity testing. There are two transmitter options.
Configuration NT is for non-live LV and MV cables. Configuration LT
is for live LV cables up to 400V and includes an additional transmitter
that imposes a specific drain current signature on the cable
investigated without line switch-off.
