But if it's midpoint grounded isn't 2 of these like a 15 kv nst with 7500v
insulation (or a 10kv obit with 5kv insulation)? I thought that was why
nst's/obits are midpoint grounded, so they can use half  the insulation on
the secondary and connection wires. Of course, it would be hard to connect
one end of the hv to the core of a pt like nst's are (I think x-ray xformers
are the same way).
