A 150 MVA, 11 kV synchronous generator has an impedance of 4Ω. What will be the p.u impedance at 250 MVA and 10 kV? (Upto two decimal)

A single line diagram of a power system network is shown below

The transformer T₂ is a bank of three single phase transformers. The rating of each transformer is 100 MVA, kV with impedance X = 0.1 per phase (p.u)

The rating of generator, T₁ and transmission line is as follow.

Generator G: 300 MVA, 20kV; X = 0.1Ω

Transformer T₁(3): 350 MVA, kV; X = 0.1Ω

Transmission Line: 0.5Ω, 230 kV.
