: For The 3 Bus System Shown In Figure 2 All Impedances Are Given In Per Unit If A Fault Occurred To It Is Very Close To 1 (16.73 KiB) Viewed 56 times

For the 3-bus system shown in Figure 2, all impedances are given in per unit. If a fault occurred to it is very close to bus 2, examine the impedance matric Zbus to evaluate the following: i. The bus impedance matrix ZBUS ii. The voltage sag at bus 1 and bus 3.

Fault 1 2 j 0.07 G ;0.05 j 0.1 3
