Question

A 25 MVA, 11 kV, 3-phase, 60 Hz, generator has its neutral grounded through a 4% reactor. It is having isolated neutral. Each generator has X 1 = 20%, X 2 = 20% and X go = 8%. If a single line-to-ground fault occurs at the common busbars with the generators unloaded at rated voltage, the fault current will be

Step 1

Step 1: Calculate the reactance of the generator The reactance of the generator can be calculated using the formula: X_gen = X_1 + X_2 + X_go X_gen = 20% + 20% + 8% X_gen = 48% Show more…
