Windmill power cable
BeeMaster2:
My sister in law lives on a mountain in Colorado and has a tall tower that she can use for a windmill. The problem is it is 1000 feet or more from her house. How far away can you transmit the wild AC.

I'm guessing pretty far since our power grid uses AC not DC.
That's why Edison lost out on the money on the beginning of the the use of industrial power grid because he promoted DC.
BeeMaster2:
I guess the real question is what size cable would be required? Would the size be in reasonable.

What does she want to power? Lights? Refrigerator? An entire modern electric house?
Chart:
Gauge: amps
10 gauge: 30 amps
8 gauge: 45 amps
6 gauge: 60 amps
4 gauge: 80 amps
2 gauge: 100 amps
1/0 (one aught) gauge: 150 amps
2/0 (double aught) gauge: 200 amps
In theory distance does matter, but with 110v ac 1000 feet shouldn't matter too much. 220v ac will travel better.
Here are charts:

BeeMaster2:
Thanks Michael. The reason I am asking is that, like a 10 gauge wire can only handle 80% of 30 amps for about 125 feet. Beyond that the resistance is too high. I will recheck this chart and see if it accounts for distance.
