Lightning Downconductor

No idea. Just make sure you thoroughly model the high frequencies. I understand that a bend in the conductor of radius 8" or less is enough to increase the high-frequency impedance enough to make the lighting prefer to jump out of the conductor. Which means 1) you don't want to use the zero-impedance conductor model, 2) you need to know the exact physical configuration of the installation, and 3) you're less concerned with info on lightning protection than you are with basic electric or physics. You'll also need to assume a waveform for the lightning stroke, which can be tricky since this is a semi-random event; that's the one place where it'd make sense to consult some lightning-protection references and utilize "standard" waveforms.
One source is the letest version of the IEEE Std C62.22.
Check the enclose article that have similarity with your research.
Good luck.
