Circuits of different voltages physically in parallel
Posted 23 December 2011 - 02:53 PM
For example, I'm thinking specifically of a 12.47kV line on the same pole as a 34.5 or 69kV line. I'm interested in modeling the 12.47kV line, but how do I take the effect of the 34.5 or 69kV coupling into account?

I poor understand you... Do you mean such a circuit?
Unless V1=V2=V3 I think this circuit would violate the laws of physics as drawn.
Can't remember how to model it, wouldn't this inducance be more dependent on the current in the conductor than the voltage? (not much help, i know)

I finally did find an answer buried away in one of my old text books. It is indeed dependent upon the current.
If anyone happens upon this post looking for an answer, I found it in "Power Systems Modelling and Fault Analysis" by Tleis. I don't recommend this book actually... but it does explain how you model my problem.
