(choose chapter or problem)

A balanced, three-phase circuit is characterized as follows:

• \(\mathrm{Y}-\Delta\) connected;

• Source voltage in the b-phase is \(150 \angle 135^{\circ} \mathrm{V}\);

• Source phase sequence is acb;

• Line impedance is \(2+j 3 \ \Omega / \phi\);

• Load impedance is \(129+j 171 \ \Omega / \phi\).

a) Draw the single phase equivalent for the a-phase.

b) Calculate the a-phase line current.

c) Calculate the a-phase line voltage for the three-phase load.
