Calculate the per unit impedance of the transformer using base values of 1 MVA

 

A 1 MVA three-phase 6,600/400V delta/star connected transformer has the following parameters per phase.

HV side: R1 = 1.307 ohms X1 = 5.228 ohms

LV side: R2 = 0.0016 ohms X2 = 0.0064 ohms

 

(a) Calculate the per unit impedance of the transformer using base values of 1 MVA and 400 V. (and .)
