A balanced (positive sequence) three-phase AC voltage source is connected to a balanced, start connected through a star-delta transformer as shown in the figure. The line-to-line voltage rating is 230 V on the star side, and 115 V on the delta side. If the magnetizing current is neglected and \({\bar I_s} = 100\angle 0^\circ A,\) then what is the value of \({\bar I_p}\) in Ampere?
1
\(50\angle 30^\circ\)
2
\(50\angle - 30^\circ\)
3
\(50\sqrt 3 \angle 30^\circ\)
4
\(200\angle 30^\circ\)
