Re: Industrial Lighting Ballasts
There are a variety of these illumination transformers available from the
various surplus dealers: Herbach and Rademan, C&H, and others. They seem
to run about 4500V open circuit, around 400-500 mA short circuit, and about
Insulation to the core is always an issue if you start stacking them. Some
have had good luck running them in oil. The shunts look easily removeable,
although I haven't tried on mine.
I have wired up 4 together to make a "big NST" at 18+kV around 250 mA that
I use for jacob's ladders and the like.
