$)$ A $60-$Hz$,100-$mile, three$-$phase overhead transmission line, constructed of ACSR

conductors, has a series impedance of $(0\mathrm{.}1826+$j$0\mathrm{.}784)/$mi per phase and a shunt$$

capacitive reactance$-$to$-$neutral of $-$mi per phase. Using the$185.510390$

nominal circuit for a medium$-$length transmission line

a$)$ Determine the total series impedance and shunt admittance of the line

b$)$ Compute the voltage, the current, and the real and reactive power at the sending

end if the load at the receiving end draws $200$ MVA at unity power factor and at a

line$-$to$-$line voltage of $230$ kV

c$)$ Find the percent voltage regulation of the line
