Hi All,

This has been bugging me for a while. Is the streamer voltage measured by 
the combination of topload geometry plus streamer length, or just by 
streamer length?  With my 4" coils, the 6" sphere had a breakdown voltage 
of 571KV by Sd=((MV/7.5)*2)*100.  Sd=sphere dia in cm.  MV= voltage in 
megavolts.  It's 18" streamer would come to 502.92KV at 1.1KV/mm.  If the 
two add together it would make the total voltage 1MV+.  If it were just 
streamer length the 502KV would not even produce corona on the sphere.  Or 
could it be that, the voltage peaks enough to produce corona, and then 
drops, as the streamer is formed.
