Good day everyone out there
I have a burning question that I wish I could really find an answer for. This is related to induced voltage from adjacent conductors (within the same multipair cable).
We have an instrument that requires 120 V ac to work and we mandate that the conductors length from control room (safe area) to the instrument do not exceed 1000 ft (305 meters). The reason is that we think if the conductors (within a multipair cable) exceed 305 meters, then induced voltage may appear on adjacent pairs.
I am not totally convinced as each pair is (of course) twisted and there is also an individual shield and an overall shield. The question here is:
Is there a relationship between the conductors/cable length and the induced voltage (given the fact that each pair is individually shielded and also twisted)?
Thank you
