Re: Higher input voltage

Yes, people have gone higher than 15kV.  The biggest reason people stick to
14.4kV, is availability of pole transformers.  There are higher voltage pole
transformers
and potential transformers, but higher voltage pole transformers are more
rare, and most potential transformers of higher voltage almost always have
120VAC seconday, not
240VAC.  So running large coils with potential transformers at high power is
more difficult with the 120VAC as the current can get very high.

Also, with higher voltage tesla systems, corona leakage and voltage
stand-off becomes much more an issue.  So design can be somewhat more
trickier.
