2.3 A generator of 80 MVA (X = 0.16 p.u.) feeds an 11 kV busbar A which is connected via a 100 MVA transformer (X₁ = 0.08 p.u.) and a line of 1.1 Q2/phase reactance to a 33 kV busbar C. Another generator of 60 MVA (X = 0.06 p.u.) feeds an 11 kV busbar B which is connected to C via a 30 MVA (X = 0.05 p.u.) transformer and a similar line. Busbars A and B are interconnected via an 80 MVA (X = 0.04 p.u.) reactor. i) 11) 111) Find the short-circuit current and MVA due to a 3 phase fault at busbar C What are the voltages at busbars A and B? What is the current in the reactor connecting A and B during the fault.
