railway RRB JE (CBT I + CBT II) Mock Test 2024 Electrical Machines Alternator and Synchronous Motors
Consider the table given:
|
Constructional feature |
Machine type |
Mitigation |
|
(P) Damper bars |
(S) Induction motor |
(X) Hunting |
|
(Q) Skewed rotor slots |
(T) Transformer |
(Y) Magnetic locking |
|
(R) Compensation winding |
(U)Synchronous machine |
(Z) Armature reaction |
|
(V) DC machine |
The correct combination that relates the constructional feature, machine type and mitigation is
1
P - V - X, Q - U - Z, R - T - Y
2
P - U - X, Q - S - Y, R - V - Z
3
P - T - Y, Q - V - Z, R - S - X
4
P- U - X, Q - V - Y, R - T - Z
