what is 120kva 3phase head in amps ? or what is the calc

 

[telectrix]

simple. 40kVA per phase. that's 1666.66666666666 A per phase. if the phases are balanced/nth308£$"^

I have a quick rough calc I always use and you just take your kva value for 3ph and divide by 0.73 this will give you approx 164amps per phase.
If its single phase then divide by 0.25 so 20kva SP is 80amps.

If you have the amps and want the kva then multiply by these values.

oops, an extra 6 went in. should have been 166.666667

I get 173 assuming power factor is 1
120000 amps /400 volts x 1.73. = 173.4 amps per phase

Edit I’ve used 400 volts rather than 415 volts.

wheres the 1.73 from

wheres the 1.73 from

It's the square root of 3.
