Question:
A three-phase induction motor in a 690-V distribution system under an abnormal condition is working on highly unbalanced three-phase voltages Ṽa= 450∠ 0°, Ṽb= 450∠−90°, and Ṽc= 900∠−225°. Determine its symmetrical component voltages V+a , V −a , and V0a , and comment on approximate motor current and power losses in the rotor and stator.
