I need to know how much electricity a machine uses in kW please.(adsbygoogle = window.adsbygoogle || []).push({});

On the machine information plate it states: 460 volts, 60 Hz, 161 amps, and it is a 3 phase.

I took the readings for the volts and amps:

Phase 1- 271 volts & 37.68 Amps

Phase 2- 271 volts & 37.62 Amps

Phase 3- 273 volts & 38 Amps

I cannot figure out the Power Factor to apply to the formula I am using:

kW= (Volts x Amps x Power Factor x Sqrt 3) / 1,000

I know Power Factor = Real Power/ Apparent Power, however I cannot figure out the real power. I believe the apparent power is (460 x 161 x Sqrt 3) / 1,000 = 128.27 kVA?

Could I just average the voltage readings and then average the amperage readings for the 3 phases and then do (Avg volt x Avg amp x Sqrt 3) / 1,000 to get the true/real power without using the Power Factor?

Are my assumptions correct? Can someone please help me calculate the electrical consumption please! Thank you
