Assume that a fault occurs on the high-voltage side of transformer T2 in the power system shown in Figure P13-2. Make the assumption that the generator is operating at rated voltage, and that the power system is initially unloaded.

(a) Calculate the subtransient fault current, generator current, and motor current for a symmetrical three-phase fault.

(b) Calculate the subtransient fault current, generator current, and motor current for a single-line-to- ground fault.

(c) How will the answers in part (b) change if the Y-connection of transformer T2 is solidly grounded?
