Yes, I've constructed a .015 uf 20 KV cap (using .15 uf, 2 KV)  and it works
perfectly.  I was pondering whether or not to by a potential transformer
this summer and use a larger capacitor.  I was thinking the .33, .47, .56 or
.68 uf 1600V capacitors could be used to make a larger MMC (.03357 uf, 22.4
KV per string) , possibly cheaper than buying several .15 uf 2000V units and
running parallel strings.  I simply wanted to check and be sure these caps
wouldn't cause a problem. I'm not an expert, and I don't have much equipment
to do testing with, so it either works or it doesn't for me.  If someone
here recommends against something I'm not going to waist money trying it
anyway, being that I'm on a constant budget.
