OT? Electrical help please

This might give you everything you need in one package with the only drawback being I wouldn"t want to run the output above ground due to lightning complications.

The current rating does not change with the inverse of the voltage for any particular winding. The voltage ratios are the inverse of the current ratios, but the current rating depends ONLY on the cross section of the wire in that winding.

I've seen pole type 60 Hz power transformers used to replace audio modulation transformers in broadcast transmitters and they sounded fine. It would be optimum for the higher frequencies to use thinner laminations in the core to reduce hysteresis loss, but if you keep the core from saturating those losses won't be too bad anyway.

Your pole top alternator works best as three phase (or two phase) so your transmission transformer needs to also have the same number of phases. If it was me, I'd hold the field current constant and let the voltage vary, that's what will get the most power from the wind (remember the available power is proportional to the wind speed cubed) and do the voltage regulation at the ground after rectification. And I'd do that regulation with a switching regulator for efficiency.

Fortunately at lower frequencies that means your mill is putting out less power (slower) so it can work fine. From the fieldlines.com forum at otherpower, do a google search from the menu to read about people doing this.
