I have some confusion on the ratio On Q118, the delta - wye ratio did not take the sqrt 3 into the consideration on the ratio. 13.2/132 But on the Q506, delta-wye ratio, sqrt 3 is taken into consideration why?

Do you know where I can borrow a copy for the exam? I have a 2007 pdf version. good enough?

Basically a few other similar across spin up tests. Why voltage at the load their answer required the load 480V divided by 1.73 then multiply by 1.73? I thought you only need divide by 1.73 My solution: Z = 0.5+j0.08 (750/1000) = 0.38 <9.1 Vt= 480/1.73 - (100<-36.9)(0.38<9.1) =...

Can I use the MVA method instead the pu method? 3 phase generator serves a 5/25kV transformer rated 6MVA. The generator's subtransient impedance is j0.39pu and the transformer rated impedance is 6%. If the generator is rated 11MVA, its contribution (MVA) under fault condition at the...
