    2. b)

      State the advantages and disadvantages of per unit system in power system analysis. 2

      Also asked:May 2023

      [7]

  3. Q3

    1. a)

      Calculate fault current in kA, if the three-phase bolted fault is i) at point Fl and ii) At point F2. (Take base of 11kV and 100MVA on generator)

      [10]
    2. b)

      State whether the following statements are true or false with justification i) In case of a phase fault at the terminal of an unloaded alternator, the sub-transient state current is smaller than the transient and steady state current. ii) The three-phase fault is more severe when the fault is far away from the generator terminal.

      [7]

  4. Q4

    1. a)

      If three-phase fault occurs at point F, find the fault current supplied by each generator in kA. Take base of 100MVA, 11kV on generator side.
