Current Impulse waveforms
Current Impulse waveforms
(OP)
I am currently developing a test circuit to output a lightning current wave with a peak of 10kA. My problem is that in order to get the required characteristics of the wave ie. rise and fall times, I need a 0.3ohm resistor. I am not sure what type of material to use that would sustain a peak of 10kA for approxiamately 30microseconds. I was considering water...any suggestions.

I once attended a high voltage testing techniques seminar sponsored by them, and a number of them seemed pretty well plugged in (no pun intended) to the suppliers for equipment like that.

from a a lenght of iron band. I would fold it in a
VVVVVVV shape and if the frequency is high enough
perhaps immerse it in water.

and search for the resistor manufacturer offering the resistors for lightning circuits. In case that you need a nonlinear resistor it could have some other name, e.g. thyrite, etc.
