A $207\mathrm{.}85$V $3-$ supply is connected to two balanced three$-$phase loads in parallel, through a feeder of impedance $(1+$ j$2)$ per phase. The first load is Y$-$conceded and has an impedance of $(20+$ j$30)$ per phase. The second load is $$and has an impedance of $(45-$j$30).$ Draw the complete circuit of the system described above.

Taking a phase voltage as reference, determine the:

$($i$)$ Phase current and the power drawn from the supply.

$($ii$)$ Line voltage at the combined load.

$($iii$)$ Current per phase in each load.

$($iv$)$ Total real and reactive powers to each load and$$ the line.

$($iv$)$ Three phase absorbed by the line$$
