Re: [TCML] NST and HV Cables
Hehe, well, let's see, since I use a 10 kVA rated polemount
distribution transformer (PDT), aka "pole pig", and the largest
available standard NSTs that I've seen here in the US are 15 kV,
60 mA, excluding the special "cold cathode" transformers or bom-
barders, I suppose it would take about 11 of them to do the
trick (or 22 of the more common 15/30's) ;^) BTW, if one finds
theirself fortunate enough to get their hands on a decent sized
(10 to 15 kVA-ish) iron core styled neon bombarder transformer
without disbursing the funds that would handily purchase a
decently equipped, late model automobile, they make a pretty
darn good supply for a large SG driven coil system. Their output
voltage is typically in the 20 to 30 kV range. From my experience
though, pole pigs work just as well, if not better, for the kVA
rating and are a lot cheaper and easier to find.

I fully agree, they do definitely look electronic, but the weight says
otherwise, the 7kG or to us, 15 pounds, is about right for an iron one.
Just how many do you use to power your Green Monster? (I'm not serious,
before someone chimes in)

Haha, Thanks for the clarification, Phil. Yep, that word has the same
meaning here on this side of the big pond, too.
BTW, just from the photos on their website, those trans- formers look a
whole lot like the solid state variety, which would red flag their
eligibility for SG Tesla coil duty. Even here in the USA, the solid state
HV
power supplies are replacing the old style 60 Hz driven, non-GFI'd
transformers for neon sign duty and the old style iron core units are
becom-
ing increasing difficult to find, although they are still showing up on
eBay.
