Electrical Engineering: Ch 13: 3 Phase Circuit (40 of 53) How to Find the Power Factor?

In this video I will find power-factor=? of a 3-phase motor consuming 4.8kW when the line voltage is 220V and the line current is 15.4A. This will require using the triangle representing the real power, P; the reactive power, Q; and the complex (apparent) power, S. And the relationship where the complex power, S, is a function of the line-voltage and line-current.

Thank you so much for the video! Keep making us smarter!

I'd recommend one small correction. You used Watts as the unit for Apparent Power (S). This would typically use VA for the units.

Does the line current is the full load current amp of the motor?

How can i calculate the reading of the input power given the output power, power factor, efficiency and voltage of 3 phase

[tchakountehyacinthe]

thank you so much. I have a question: the power consumed by the motor is it the real or reactive power since the motor have both inductances and resistor coils?

[abdeldjalilyahi]

Professor, isn't it the unit of apparent power : Volt-ampere (VA) and not Watts (W)... I think you made an oblivious mistake there.

Thank you sir
I have a question please
I have a motor nameplate, the information given :
I = 27.13 A
V = 415 V
Output power = 15 kw
And p.f is 0.87
When i used the method which you have explain i got 0.76 p.f and it does not matching p.f which is given ( 0.87) 😅
