Web17 mei 2024 · Bonus question : What may be nature of armature reaction if machine is operating on lagging pf while being over excited. PS: I know that even if I'm right, in most of cases, over exciting will mean increasing E much above V so that we'd have leading pf but still, I thought atleast books must've included this possibility... Web31 jul. 2024 · The leading power factor can be achieved by using the capacity load in the circuit. Because the pure capacity load current leads the voltage by angle 90°. We can also get leading power factors in the combination with resistive capacitive loads in the circuit. Consider the wave forms as I shown below,

Power factor - PF (COS φ) - Electrical Classroom

WebPower factor (PF) has a value between zero and unity. The nature of the power factor depends on the relationship between the current and voltage phase angles as: As reactive power Q = V I sin (α − β), its sign depends on the nature of PF: Q is positive for lagging PF. Q is negative for leading PF. Q is zero for UPF. Web26 dec. 2024 · 1. more at leading pf. 2. less at lagging pf. 3. same at leading and lagging pf. 4. more at lagging pf and less at leading pf.
