dpc, your speculation about the OH line being "2nd order" on the secondary is probably correct and I commented to that effect in my original post. But I don't think assumptions like "it doesn't matter" belong in modern professional engineering practice. It should be characterized before being...
Jghrist, That may very well turn out to be the case, but I think I should characterize it before ignoring. Regarding all the uncertainty in data, even though it's there, I have done several failure investigations of events on large industrial power systems and in every case that I can recall...
I'm trying to model a 12.47 kV distribution system (in the SKM PTW program) with untransposed irregular flat crossarms; maximum line length is about 10 miles.
Typical spacing on flat crossarms is phase A 0", phase B (middle) 26", and phase C 88". No transposing - i.e. phase B stays in the...
