Answer / 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.

What can make the the overloads operate when a star delta three phase motor starts?

In Air circuit breaker LSIG protection unit is used. Without fault in cables (2 runs 3Cx150Sq.mm Copper, 1Kv grade, XPLE armored cable IR value is more than 550Mohm @ 500V Megger) and load section Long time Overcurrent protection is triggers and trips the unit. We changed LSIG protection with new factory tested unit. Even then fault is persisting. Please suggest the possible causes
