Ideal Transformer: Solve for Turn Ratio, kVA Rating, Primary Current

[eehelp150]

Homework Statement

Ideal Transformer:
rated: 11000/4600 V
secondary current: 30A

Find turn ratio, kVA rating, primary current

Homework Equations

S=VI
N=V2/V1

The Attempt at a Solution

Are these correct?
Turn ratio: N=V2/V1 = 0.418
kVA = S1*I1 = S2*I2 = 4600*30 = 138kVA
Primary current: V1*I2 = V2*I2=>I1=(4600*30)/(11000) = 12.5A
