On a 3 phase Y480-208/120 stepdown transformer, if it's rated for 150,000VA, how would I go about calculating how many amps would be on its primary at max load?
208 x sqrt(3) = 360+/- v
120 x 3 phases = 360v
Would I just take 480v / 150kva???
Or do I have to do something with the ratio of the 480/360 or take into account the 480 Y?
