Re: Re: transformer question

Are you sure? With both the secondaries AND the primaries in series? I've
often wondered about that configuration and have never seen any thought
or questions about it before.

Just to be sure you (and Reinhard!!) get it, I am talking about LEAVING
THE CASES UNGROUNDED. Just from a hypothetical, and not neccesarily
practical, point of view. If the primaries are in series, then there
would be no extra stress on the insulation for the seriesed secondaries,
as the total volatge would be equal to that of one original transformer.
...and the current would be doubled, would it not?
