A synchronous generator is feeding a zero power factor (lagging) load at rated current.
The armature reaction is
-
- magnetizing
- demagnetizing
- cross-magnetizing
- ineffective
Correct Option: B
| The distributor of current and fluxes with phase angle φ = + | ||
| 2 |
| For lagging load is the current will be shifted in space by an angle | ||
| 2 |
from maximum emf which coincide with centre of pole. The field created by the armature reaction mmf will be in opposite to main field flux and will therefore by wholly dimagnetizing effect.
