voltage drop

[Dennis Damm]

first a little about my turbine. it is a 12 ft,3 phase, operating at 12 volt after rectification,it has 60 turns of 2 in hand # 15 wire in the coils.it is an early version of otherpower.com wind turbines made out of junk. it works very well and have seen it produce 60 amps on a few occasions.Right now my controls are in my greenhouse at the bottom of the tower. let me say that a greenhouse in michigan is not a good place for batteries and electronics, as the tempature extremes can be great. i would like to move everythin into my basement which is 150 ft. from the base of the turbine. the question is do i have to concern myself with voltage drop

on the 3 phase A/C transmission to the house then threw the bridge rectifiers to charge my batteries?

I have searched the previous posts in here and after 300 of 1350 posts i kinda gave up

as none of them asked this question. any help would be greatly appreciated.

I am thinking about using #2 urd al. which has a voltage drop of 4.9 at 150 ft

using the formula 2k x length x amps divided by C mil

For a run of 150 foot to reach the diode bridges you are looking at a serious investment in cable. A better balance in circuitry would be rewind stator to higher voltage; run the numbers through calculator I've linked in. Maybe a redesign on the equipment locker to move it alongside (outside) the greenhouse would be a better bet?
