railway RRB JE (CBT I + CBT II) Mock Test 2024 Electrical Machines Alternator and Synchronous Motors
If a set of negative sequence voltages is applied to the stator winding of an alternator:
1
the direction of rotation of the stator field is the same as that of the rotor
2
the direction of rotation of the stator field is opposite to that of the rotor
3
the direction of rotation of the stator field is opposite to that of the rotor and give rise to an alternating field in space
4
There is no relation between negative sequence voltages and the stator field and rotor
