    Fault Current Analysis (PU method)

    @Zach Stone, P.E. I am working on Fault Current Analysis quiz question 9 at electricalpereview.com. And I am trying to use PU method to solve it. Set Vb=4160V, Sb=1.5MVA Zg, pu (Zpu at generator) = 0.079 pu * (1.5MVA/50MVA)=0.00237pu Zx, pu (Zpu at transformer) = 0.075pu Since Zg, pu is...
