Re: [TCML] multiple miniature transformers

["Neal Namowicz" <neal@xxxxxxxxxxxxxxxx>]

This is definitely one I have a little experience with. I started 
accumulating nst's a while ago, and then began tying them together. At the 
moment, I'm up to 6, 9kv/30ma. I have them mounted on a 2' x 2' platform 
with casters. As my daughter's boyfriend and I were lugging it up the 
basement stairs for halloween, I too wondered why I just didn't get a small 
pig. However, there's still the issue of current control that I don't have 
to deal with, as I would with a pig. I would stick to using my variac, 
rather than switching them on individually, too. I prefer to ramp the power 
up slowly, just in case. I'm only using a safety gap for them at the moment, 
but I try to be conservative and not push them beyond 80-85% on the variac.

Neal.

Wouldn't 10 neon sign transformers and associated equipment be just about as 
bad as lugging around a pole pig or maybe even worse?

 Hi All,

 A couple of years back I made a TC powered by 4 parallel NSTs,
 providing 1KVA, which worked reasonably well.  I was thinking about
 extending the idea using 10 larger (identical) NSTs to provide 10KVA.
 I would individually protect each NST using something like a Terry
 filter, and also place a switch on the mains side of each transformer,
