railway UPMRC SCTO 2024 Mock Test Electrical Machines Alternator and Synchronous Motors Salient Pole Alternator Operation
How does armature reaction affect the main field flux in an alternator when the load has a power factor of zero leading?
1
Armature reaction distorts the main field flux and does not affect its strength.
2
Armature reaction distorts the main field flux and weakens it.
3
Armature reaction strengthens the main field flux and does not distort it.
4
Armature reaction weakens the main field flux and reduces the generated EMF.
