In a balanced D-D circuit the D-connected source produces VAB 2400ff45 Vrms and a positive phase

In a balanced D-D circuit the D-connected source produces VAB ¼ 2400ff45 VðrmsÞ and a positive phase sequence.

The phase impedance of the load is ZD ¼

200ff45

V=phase. Find the three source voltages and the phase impedance in the equivalent Y-Y circuit.
