re: Secondary height
I have a 6.0" dia secondary with a 14 turn primary made of 3/8" copper tubing
wound on a 30 degree plastic form. The first turns on my secondary sit right
down to the level of the first turn of the primary. I did not realize it
before with lower power levels, but now that I'm trying to put in 3 to 4 kva,
I find that I have the primary/secondary coupled too tightly. I have a very
strong corona that forms from the top of the secondary down to the top of the
primary. As I increase power levels, this corona forms streamers and breaks
down. I have raised the secondary up three to four inches to eliminate this
problem.
What diameter is your secondary? What power levels to you plan to run at?
If I had to do it over, I would have wound a flat primary. It would have
been much easier to build and I think it would work better at the higher
power levels.
