Draw the positive sequence network impedance model.
2) Draw the negative sequence network impedance model.
3) Draw the zero sequence network impedance model.
4) If generator two was grounded through a grounding reactance of 0.2 PU, where in the
three sequence networks would it show up? Why? Redraw the sequence network that
changes.
5) If a bolted three phase to ground fault occurs at bus 2, find the fault current
contribution of generator G1. Assume a prefault voltage of 1 per-unit at bus 2.
6) If transformer T1 connection was changed to be a Y-Y connection, would that change
affect the shape of the positive sequence network?](/v2/_next/image?url=https%3A%2F%2Fcontent.bartleby.com%2Fqna-images%2Fquestion%2F297f5383-848f-4ea4-b3b0-01d2f60fe37d%2F668d1950-4ecb-4ec8-95c3-521763dbd8ff%2Fm4epfft_processed.png&w=3840&q=75)
