It's Me Again, After a Long Recess, and I've got problems...
Original poster: "Ryan Ries by way of Terry Fritz <twftesla-at-uswest-dot-net>" <spud-at-wf-dot-net>
It's been several months since I've posted anything to the list, but I
have some pretty severe problems.
Today is the first day that my friend and I have started working on the
coil again in a couple months, and we have still not gotten the 10kva pole
pig to function correctly. It only buzzed little 6 inch sparks. The
ballasting checks, the spark is decent, the primary and secondary coils
check. The only thing left to point at was the capacitors. I fired up
Wintesla, and entered in my transformer. 12400v -at- 0.81a. It calculated
the matched capacitance to be 0.173µf ! Is this correct? We only have
0.037µf right now, and that's the highest we can get. About a year ago,
someone on this mailing list was generous enough to sell me some MMC caps;
100 pieces for $20. They were 0.21µf -at- 600vac. They were the best caps we
have ever had, but they can't reach a capacitance like that. As
high-school students, neither of us have the budget to buy a capacitor (or
that amount of MMC caps) of that magnitude.
If anyone would be willing to offer any advice, I would be grateful.
Thanks,
Ryan Ries
