Several techniques are of use:
1) Sink it in oil... Assuming the sucker was good for 2.5 kV before, it's
now good for 7.5 kV, or so.  What sort of hipot testing do they do from

2) Various back to back cascades, using the MOT as an isolation transformer
(heavy, but it will work...)
3) A healthy dose of hoping..
