MCQ
Flux density under trailing pole tips in case of generator will:
- ✓increase
- Bdecrease
- Ceither increase or decrease
- Dnone of the above
✓
Answer
Correct option: A.
increase
$\text{LPT}=$ leading pole tip
$\text{TPT}=$ tailling pole top
Considering armature reaction.
where $\text{GNA}=$Geometrical axis
$\text{MNA}=$ Magnetic neutral axis
here clearly see that $\text{TPT}$ side flux increases due to armature in case of generator.
