I discussed this with Peter Dahl when ordering a transformer which I
wished to use both here and in a 50-Hz. country.
He explained that, especially as transformers get larger, a 50-Hz. rated
transformer will have much more iron in it. There is no problem using
such a transformer on 60 Hz., but a 60 Hz. transformer used on 50 Hz.
will draw more current at idle, heat up and burn out.
The roughly 3.5 kVA transformer that I ultimately ordered weighed 30%
more than an equivalent one rated for 60 Hz. only. He assured me that it
would work fine on 60 Hz.
