For a power system the admittance and impedance matrices for the fault studies are as follows.
$$$\eqalign{
& {Y_{bus}} = \left[ {\matrix{
{ - j8.75} & {j1.25} & {j2.50} \cr
{j1.25} & { - j6.25} & {j2.50} \cr
{j2.50} & {j2.50} & { - j5.00} \cr
} } \right] \cr
& {Z_{bus}} = \left[ {\matrix{
{j0.16} & {j0.08} & {j0.12} \cr
{j0.08} & {j0.24} & {j0.16} \cr
{j0.12} & {j0.16} & {j0.34} \cr
} } \right] \cr} $$$
The pre-fault voltages are $$1.0$$ $$p.u.$$ at all the buses. The system was unloaded prior to the fault. A solid $$3$$ phase fault takes place at bus $$2.$$
The post fault voltages at buses $$1$$ and $$3$$ in per unit respectively are
