A three-phase generator is rated 20 MVA, 15.4 kV. If its reactance is specified as 6%, then the value of actual reactance of the generator winding is
Actual reactance ($Z_{actual}$)
The power system network consist of 5 bus system, then the order of the $Y_{bus}$ matrix is equal to
$\circ$ N x 4
$\circ$ n x 1
$\circ$ 5 x 5
$\circ$ 4 x 4
