- Draw the per-phase equivalent circuit for phase A in per-unit, using \( V_{b L N}=200 \mathrm{~V} \) and \( S_{b 3 \Phi}=18 \mathrm{kVA} \). Show numerical values of all impedances and the source voltage. - Solve for the line current leaving phase B of the source as a phasor quantity, in both [pu] and \( [\mathrm{A}] \). That is, calculate \( \bar{I}_{B B^{\prime}}[\mathrm{pu}] \) and \( \bar{I}_{B B^{\prime}}[\mathrm{A}] \). Figure 2: Balanced three-phase system
