Current Rating of an AC Generator

[Sent]

Hello,

I'm a bit confused on the term current rating in an ac generator. Is it the one in that I can get in the formula:
kW= V*I*PF*sqrt(3) ? or the one in kW= V*I*sqrt(3)? The problem is the data that I have is V, PF, kVA only. I can compute the kW using those data but I'm abit confused on those formulas.

Also, I've read in some books that there are times that if the generator is 3 phase, the formula has a sqrt(3) why is that so?

Thanks!

It's the first equation. Naturally that means the power depends on the power factor of the load.

It's the first equation. Naturally that means the power depends on the power factor of the load.

So for example I have a 875kVA and a .8 power factor, my kW will then be 700 kW right?

According to the first equation, If I have a volts of 2400, it will be 700 kW = 2400 * I * .8 *sqrt(3)
That way I can have the current rating?
