I have got an interesting situation. I wonder if anyone has an answer. I have a 12 conductor, 10 AWG cable that runs approx. 750 foot. It carries 480 volt on two legs to a transformer. Ground on one conductor. Six conductors are 2 seperate three wire control circuits ( 480 V control ). These six have no connection to the to legs of 480 other than incased in the same cable. The other three cond. are spares.
My problem is when I energize the two 480 conductors, I am getting stray voltage back on the six control wires. Why ??? Is it possible they are "bleeding" over in the cable. If so, what can I do ?
