A $3-$phase $75$ MVA, $11$ kV $,$ Y$-$connected generator with a solidly earthed star connection has the following sequence component impedances:

$Z_0=j0\mathrm{.}17$ zero

$Z_1=j0\mathrm{.}44$ positive

$Z_2=j0\mathrm{.}29$ negative

Terminal A of the generator is shorted to ground. Determine the symmetrical components of $I_{A^{\text{'}}},$ then use the symmetrical components of $I_A$ to determine the symmetrical components of $I_B$ and $I_C.$ Use the symmetrical components to determine $I_{A^{\text{'}}}{I}_B$ and $I_{C^{\text{'}}}$ then draw the symmetrical components of $I_{A^{\text{'}}},I_B$ and $I_{C^{\text{'}}}.$
