[BC] Transformers needed

[Bill Sepmeier]

Greetings, all ...

I'm looking for some relatively small transformers so that I can 
complete a micro hydro electric project out at my place.

I have a 3kW 6 phase alternator on a 10" Francis turbine that 
produces 60VAC / 500 watts max per leg, as two three phase WYE 
outputs.  I want to step this up to 600 VAC for transmission over 
about 900 feet, then step it back down again.  Four 3 phase xfmrs, or 
12 single phase xfmrs will work, but I'm having difficulty finding 
anything at 10:1.  I could use 5:1, minimum, it'll just require 
bigger interconnect wire.

If anyone has a line of these little beasts, new or used, please let 
me know....

Bill
