stup up transforner

I've never tested a stepup transformer witha 120v primary and 15000v sevondary for outside fluorscent lights before, and I'mnotsure the best, safest way todo it. I've already verified the transformer works, so I know it's one of the fluorscent lights that is havinga problem. All the lights are wired in series, so one of the fluorscent lights must be burned out. How do I safely test these lights? At 15000v and low amps, will a wirenut hold? Are there special wirenuts for a higher voltage?

the wirenuts you are using should have a manufacturers rating on them, if not get the data sheet from the manuf. My recollection is that the ones I use are only rated for 600V.

MV terminations are a whole different animal, you need to control stresses with special terminations.

As far as testing the transformer you would do a DAR and PI test on the windings, a TTR to verify ratio, and a winding resistance test.

I've never hear of 15000V fluorescent lights. Are these similar to neon lights.
