Test Academy | A 3-bus network is shown. Consider generators as ideal voltage sources. If rows 1, 2 and 3 of the Y bus matrix correspond to bus 1, 2 and 3 respectively, then Y bus of the network is [ − 4 j j j j − 4 j j j j − 4 j ] , [ − 4 j 2 j 2 j 2 j − 4 j 2 j 2 j 2 j − 4 j ] , [ − 3 4 j 1 4 j 1 4 j 1 4 j − 3 4 j 1 4 j 1 4 j 1 4 j − 3 4 j ] , [ − 1 2 j 1 4 j 1 4 j 1 4 j − 1 2 j 1 4 j 1 4 j 1 4 j − 1 2 j ]

Question

A 3-bus network is shown. Consider generators as ideal voltage sources. If rows 1, 2 and 3 of the Y_bus matrix correspond to bus 1, 2 and 3 respectively, then Y_bus of the network is

Options :

$[\begin{matrix} - 4 j & j & j \\ j & - 4 j & j \\ j & j & - 4 j \end{matrix}]$
$[\begin{matrix} - 4 j & 2 j & 2 j \\ 2 j & - 4 j & 2 j \\ 2 j & 2 j & - 4 j \end{matrix}]$
$[\begin{matrix} - \frac{3}{4} j & \frac{1}{4} j & \frac{1}{4} j \\ \frac{1}{4} j & - \frac{3}{4} j & \frac{1}{4} j \\ \frac{1}{4} j & \frac{1}{4} j & - \frac{3}{4} j \end{matrix}]$
$[\begin{matrix} - \frac{1}{2} j & \frac{1}{4} j & \frac{1}{4} j \\ \frac{1}{4} j & - \frac{1}{2} j & \frac{1}{4} j \\ \frac{1}{4} j & \frac{1}{4} j & - \frac{1}{2} j \end{matrix}]$
