Determine the new per-unit reactances of the following:

a. Generator: 60 MVA, 11 kV, Xg = 50 %

b. Transformer: 75 MVA, 13 kV, X = 10 %

c. Transmission line: X = 20 ohms

d. Load: 35 MVA, 12 kV, Z = 0.2 +j 4.5 p.
u.

e. Motor: 50 MVA, Xm = 25 %

Use 100 MVA as power base and 10 kV as voltage base.
