Electrostatic Coupling of Transmission Lines

[magoo2]

In the past, I've done a few calculations of electrostatically coupled voltage from one transmission line to another. Usually, the results don't consider the line distance because the geometry is the same. I assume that the calculation is done in a per unit basis (per mi or per km). The methodology involves the potential coefficient matrix [P] and it's inverse, the capacitance matrix [C] and is based on some M.H. Hesse papers.

I'm now dealing with a situation where one of the lines goes through a transposition 30 % from the source. The other is really a fence. Am I right in concluding that I simply take 30% of the first section value and add it to 70% of the section section value to get the electrostatically coupled voltage for the entire fence.

Sounds logical to be, but I just wanted to confirm it. thanks.

I just realized that this particular forum is for transmission structure engineering, so I'm going to post this over under Electric power engineering.
