Homework Help: 11kV Distribution System Fault Analysis using Symmetrical Components

  1. Aug 11, 2015 #1
    Hi could someone check my answer to the question below.


    My Answer:

    [tex] I_{fA} = 3I_{1A} = 3I_{2A} = 3I_{0A} \Rightarrow I_{fA} = \frac{3E}{Z_1 + Z_2 + Z_0} = \frac{33kV}{20+20+30} = 471.43A[/tex]

    Then using the same method I got [tex] I_{fB} = 942.86A[/tex]
