Hello I am just stuck on a three phase transformer question.
A 5KVA, 3 phase transformer, Y-Y (Star) has a primary line voltage of 500V and secondary line voltage of 200V, supplying to a load of 75 ohm with the line impedance of 40. Calculate the line current in primary.
I have attempted it by adding doing the following 500/(75+40)=I ... but the answer does not seem to be correct
