Answer Posted / Sanjeev Kumar Yadav
Shifting the neutral of a three-phase power system by 20 degrees is known as phase displacement. In a three-phase induction motor, this can cause unbalanced currents and voltages in the stator windings, resulting in reduced efficiency, increased power loss, torque pulsations, and noise. However, the exact magnitude of these effects depends on various factors such as the severity of phase displacement (20 degrees), load conditions, and motor design.
