Right. The transformer(s) will be tossed.
Any such tests have to be only "design" tests.

True.

I totally agree. I'm just looking for something
we can use in our lab that doesn't cost too much
for 140 pieces, and won't be failing all the time.
I used to have to replace 10kV-rated KiloVolt
$150 reed relays running at 6kV, every 6 months.
So I have a healthy respect for those horrible
gradual potting failures.
