A 3-phase power system is represented by one line diagram as shown in the figure below:







The ratings of equipments are the following:

Genrator (G) : 15 MVA, 6.6 kV, $X_1$ = 15%,

$X_2$ = 10%

Transformer : 15 MVA, 6.6 kV delta/33 kV star,

$X_1=X_2=X_0=6$%

Line reactance : $X_1=X_2=2\Omega and{X}_0=6\Omega$

If a SLG fault occurs on bus bar B, then the fault current is _______ p.u.

1. 0
