Joe90's BIG RAT Build.

[Clive S]

Wow that's some serious brewing activity...

Don't worry about phases in your calculation. Just take that single phase value, 4A or so and go with it.

If your Calcs end up needing more than 1000kVA you're probably not quite right, or you're building a beast. Most builds here use around abouts 500kVA.

I won't comment on the information you've already seen from my build log - no point hearing the same persons opinion twice. Although I will add that I think I was a little conservative with my secondary voltages in retrospect, and could have gone higher.

That would be some big machine

Yes, I think there's been a of 'k' inserted where it shouldn't be. Lol

Can you imagine the size of the donut for a 1000kVA toroidal... Probably about the size of a truck tyre inner tube blown up to its max.

Yes, 1000kVA would be about 750 hp. You'd need your own substation to be installed. Even 500kVA / 380hp would be pushing it. You can safely drop the k....

Yes, I think there's been a couple of 'k's inserted where they shouldn't be. Lol

Ooops. :)

Force of habit I'm afraid... work requires kV / MV... You know what I meant!!

I think everyone knew what you meant, even me. When I joked about it, I'd missed the fact that Muzzer had already followed up on Clive's original subtle highlight of it, otherwise I'd have said nowt.

KV (Strictly NOT kV if I'm correct) and MW is one thing, I do those every working day. But MV (as opposed to mV)... That really is fun and games! The trick is keeping it in the wires.
