A three$-$phase, $765-$kV$,60-$Hz$,300-$km$,$ fully transposed transmission line has the following positive$-$sequence impedance and admittance:

Z $=0\mathrm{.}017+$ j$0\mathrm{.}4=0\mathrm{.}4<87\mathrm{.}14$deg

y $=$ j$5$x$10^-6$ S$/$Km

Determine the ABCD parameters of the transmission line. Compare the B parameter with that of the nominal model. briefly comment on your answer, and make the necessary assumptions.
