How to solve

Generat$$rler:

$U=33kV$;$S=25$MVA,$x_d^{\text{'}\text{'}}=j0\mathrm{.}125pu$

Hatlar:

$x_{AB}=x_{BC}=x_{CD}=x_{DA}=j10\mathrm{.}89$Ohm

A Barasinda meydana gelen $3$ Faz K$$sa Devresi i$$in$,$ Devrenin Thevenin E$$de$$eri yard$$m$$yla K$$sa Devre Ak$$m$$n$$n ger$$ek degerini bulun.

$S_{\text{B}\text{A}\text{Z}}=100$MVA

$U_{BZZ}=33kV$
