suspect I am seeing a higher voltage at the cap upon conduction. I
suspect I can check this with a simple static gap? Maybe using identical
1" brass sphere's, I could run it a few seconds and see if it will run at
120bps in this mode. Setting the sphere gap to 0.5" should require an arc
voltage of ~28kV to arc across. Assuming I leave the ballast variac at
it's SRSG position (same current), I could begin decreasing distance
until I get breakover. The arc voltage should be able to be back calc'd
from the distance.
Take care,
Bart
I think such tests are very worthwhile. I used that method to
check my HV probe calibration, and it seemed to agree very
well.
cheers,
