Hello everyone please can someone calculate the current for a three phase machine at 28kw unity pf I already I have seemed to forgot how to use the calculator cheers in advance 27kw three phase

No motors on the 'machine'?

 

[telectrix]

not without knowing the voltage.

not without knowing the voltage.

Now you are just being picky....

 

[m4fiaafg]

The total power is 28 kw three phase 400 v

corse not, it's a time machine.:ack2:

Now you are just being picky....

why? could be 230V 3 phase, 690V.........

Are you a trainee? If so request access from a mod to the trainee section.

Also we don't just do peoples homework for them, we will guide though if you give it a try first.

@ OP.ever seen this?

P=√3VIxpf

why? could be 230V 3 phase, 690V.........

I was joking mate.

To the OP. Have you tried Google. That will give you the formula you need. May even do the calcs for you.

Funnily enough I'm sat in an Amtech design course today, so I'll ask the tutor.
