RE: series of transformers for high voltage?

It would work if the insulation ratings of each consecutive transformer
were sufficient.

If (for argument's sake) you have (2) 120V/4160V transformers and with
the first one you step 120V up to 4160V, then the insulation on the
second transformer has to withstand 4160 on the primary, and more than
30 times that on the secondary. If you happen to have transformers with
a 120 kV rating you are in luck. Otherwise your circuit will not last
more than about half a cycle.

But yes, in theory you simply multiply all the turns ratios together and
get one big step (or down) effect.

Hello,

I'm interested in Tesla coils and high voltage... Is it possible to use
a series of transformers to obtain high voltage, as in the sketch below?
 >From what I understand of transformers, Vout=Vin * (n2/n1) *
(n4/n3)*(n6/n5) and with this wiring one would save on the TOTAL number
of turns. Something must be wrong - otherwise it would used!
