PFC confusion
Original poster: "Steven Ward by way of Terry Fritz <twftesla-at-qwest-dot-net>" <srward16-at-hotmail-dot-com>
Maybe its the cheap clamp ammeter made by Radioshack, or the AC is just
messed up a bit and tricking the meter. But, my 2 15000v 60ma NSTs are only
drawing like 8A!! Im using a 408uf PFC bank, and the reading is not from a
tesla powered situation, just a jaccobs ladder. I know that my current will
be more when its on the TC. But here is the confusion:
1. how exactly is this thing to be wired? like this?:

Is this ok? Because this leads to more confusion!!
Since all of the caps are in a parallel setup like

ect...
Why is it that when i tap the clamp meter at different points on the
capacitor chain i get different readings?? At the input side i read the
very low reading, but near the NST primary, i get some 15-20A. Im guessing
that this is a sign of it working correctly, making the mains input look
like less of a draw. I thought that since tha caps are directly paralleled
to each other that there would be no difference anywhere, ie. it would read
8A everywhere.
Well i cant complain, im much happier pulling a 16A load than a 24A load.
With all of these additions, my coil needed some remodeling. Now i dont
have all of that luxurious extra space between everything like before. Now
i have about 10sq" total of free floor space on my 24" diameter base(i knew
there was a reason that the store only had the 24" circles in stock ;))
