For the system shown in FIGURE 2, using a 10 MVA base, calculate the fault MVA levels through each unit and the base "voltage" MVA across each unit for a fault at F. Draw the impedance diagrams showing the fault levels and the base "voltage" MVA across each unit for:
(a) bus section switch B open and A open
(b) bus section switch B closed and A open.
Other circuit breakers are closed.
The generators have the same rating and characteristics.

The Attempt at a Solution
My attempt is 4 pages long and so I have not been able to create in Latex form so I have attached the question and my answer in PDF. I am hoping someone can take a look at this and advise if its ok or if there any areas I have made a mistake etc[/B]
