For the power system shown in Fig. 7.2, determine the network admittance matrix ([ \(\left.\mathrm{Y}_{\text {Bus }}ight]\) ).

1) \(j\left[\begin{array}{ccc}-20 & 15 & 15 \\ 15 & -25 & 10 \\ 15 & 10 & -30\end{array}ight]\) p.u.

2) \(j\left[\begin{array}{ccc}-25 & 10 & 5 \\ 10 & -35 & 5 \\ 5 & 5 & -15\end{array}ight]\) p.u.

3) \(j\left[\begin{array}{ccc}-20 & 5 & 10 \\ 5 & -30 & 15 \\ 10 & 15 & -35\end{array}ight]\) p.u.

4) \(j\left[\begin{array}{ccc}-15 & 30 & -40 \\ 30 & -20 & 20 \\ -40 & 20 & -35\end{array}ight]\) p.u.
