Question $1(20$ marks$)$

Figure $1$ below shows the conductor configuration of a completely trans$-$posed three$-$

phase overhead transmission line with bundled phase conductors. All conductors have a

radius of $0\mathrm{.}74$ cm with a $30-$cm bundle spacing. $($a$)$ Determine the inductance per phase

in m$($H$)/($k$)$m and in m$($H$)/($m$)$i$.($b$)$ Find the inductive line reactance per phase in $($x$)/($m$)$i at $60$

Hz $.($c$)$ the line$-$to$-$neutral capacitance in n$($F$)/($k$)$m per phase and in n$($F$)/($m$)$i per phase; $($d$)$

the capacitive reactance in V$-$km per phase and in V$-$mif $($g$)$ the total reactive power
