Question

in a synchronous generator operating at zero power factor lagging the effect of armature reaction is​

Answer 1

Answer:

At lagging zero electrical power factor, the armature current lags by 90° to induced emf in the armature. As the emf induced in the armature coil due to main field flux thus the emf leads the main field flux by 90°. ... Hence armature reaction of the alternator at lagging zero power factor is a purely demagnetising type.
