If excitation will increase, then what will be the effect
on power factor? Will it decrease or increase?
Answer Posted / bala sundaram
it will depend upon a machine.
alternator:
excitation current will increase means power factor will decrease bcoz E is increased & resultant E induced and load current phase angle is reduced so power factor reduced
synchronous motor
on over excitation it will increase a power factor.
