Question #201792

Let Vab =300 V in a balanced Y-connected

 three-phase generator with a phase

 sequence acb, then Vbn is:

 Select one:

 a 173L-30° V

 b 173L-150° V

 c 173L+150° V

 d 173L-270° V

 e 173L +30° V

Look at the diagram:


The phase difference between Van and Vab is -30°. The phase difference between Van and Vbn is -120°. Thus, the phase shift between Vab and Vbn is -150°. The magnitude is


The answer is
