Induction machine power factor
WebFirst, we need to calculate the apparent power in kVA. We can do this by multiplying load voltage by load current: As we can see, 2.308 kVA is a much larger figure than 1.5 kW, which tells us that the power factor in this circuit is rather poor (substantially less than 1). Now, we figure the power factor of this load by dividing the true power ... WebNov 12, 2024 at 18:25. No, I believe reactive power is slightly more at no load because the voltage across the magnetizing branch rises slightly. – user80875. Nov 12, 2024 at 19:20. I checked some motor performance data and found that my assumption is not correct. See revised answer. – user80875.
