[Test-Equipment] Another boat anchor - Del Electric High voltage supply?

[rbethman]

I once again point out the need for some significant safety using 30KV 
out in an open area.

Sorry for "speaking" of 40 to 50KV levels.

My past "life" included Hi-Potting significantly over 100KV.  Those 
devices had you "manually" set the "highest" voltage it would go to.  It 
was then "internally" motor-driven to ensure that it did NOT rise too 
fast.  The leakage current was something you could NOT over ride.

I've watched "things" come unglued at those higher voltages.  That was 
why we had a "safety cage" and the floor was 1/2" copper plate.  This 
was also attached to the same ground the Hi-Pot tester was grounded to, 
not to mention the array of ground rods and grid.

That 1/2" copper plate had to be replaced on several instances, after 
things came apart and damaged it.
