Aluminum to brass
Aluminum to brass
(OP)
We are currently building a new substation and brass 4 hole pads were purchased for connecting our conductors to our equipment. We will be using 556 aluminum conductors and connecting to an aluminum pad on the equipment. Can anyone tell me if this is acceptable and, if possible, point me towards any literature that supports your posistion.
Thanks
Thanks

Other experts here invited to comment.
We nearly burned up a generator terminal box at 11kV where the contractor had bolted directly aluminum lugs to the copper busbars of the generator. The solution had to be to go out and get special copal lugs fitted to the cable terminations. After only around 10 hours operation at around 1500A.
Are you really in Hilo where it never stops raining??

You are correct, about 5 years back we had a unit come apart and we replaced it with a new one.
We are about 30% renewable here between solar, wind, hydro and geothermal.

I was also in Hilo a few years ago visiting family and friends. My supervisor was born and raised there. Also Ed Case (candidate for US House) is a cousin.
I'm interested in wind generation. Any idea how much there is on the Big Island?

30MW is probably a fairly significant fraction of your total capacity? I could see that being a problem.
