For the experiments "I" want to do with inhibited discharges, I would want 
to sense currents of a few amps only, at the resonant frequency of the 
coil. That is a little too low to get good signal-to-noise ratio from a 
Rogowski coil IMO. I would rather use a ferrite-cored CT with Faraday 
shielding.

However, if the ground strike develops fully into a bright arc, I estimate 
it would pack hundreds of amps peak current with high frequency components 
into the tens of megahertz. I'm not interested in measuring this aspect but 
I do want to stop it from blowing the digital scope to hell.
