Question $5[15$ points$]$:

A $100-$MVA $230/115-$kV power transformer has a per$-$unit equivalent circuit as shown below.

The per$-$unit primary voltage of this transformer at $80$ MVA $0\mathrm{.}8$ PF leading load is:

$V_P=V_S+I_S{Z}_{eq,S}=(\frac{1\mathrm{.}0}{{?}_0}pu)+(\frac{0\mathrm{.}8}{{?}_{36\mathrm{.}87}}pu)(0\mathrm{.}0125+j0\mathrm{.}0588pu)$

Sketch the phasor diagram of this transformer. Label all phasors with calculated values.
