Cable selection set
The
InterSelect cable selection set is used for positive selection of single
cable or line from a bundle of cables.
For positive
selection, unipolar current impulses are sent into the line under test.
The receiver and
the clip-on instrument are used for measuring the intensity and the polarity
of these current impulses.
All other cables
have a weaker signal with an inverted polarity.
Due to the use
of the cable selection set wrong cable cuts will be avoided.
The InterSelect
impulse generator S11 is used for non live power, signal and low voltage
cables.
Thanks to their
compact size and insulated design, both of these generators can be placed in
closed distribution cabinets, so a supervising person won’t be necessary
during cable selection.
The cable selection set consists
of the following devices:
-
Impulse generator S11 sends
impulses into the non-live cables
-
The receiver S10 allows the
identification of a cable
-
Flexible probe to receive
the selection pulse
