WebJul 15, 2024 · An easy way to think of it is as three separate single phase circuits with the voltage as V/√3. For 400V phase-phase that would be 231V phase-neutral so the power on each phase is I x pf x 231. Add the individual powers in each phase together and it should give the same as the formula you originally quoted using the average of the phase currents. WebMay 14, 2024 · So you would think of this as: This circuit draws 10 amps at 220v and 3 amps at 110v for a total of: (2200 watts plus 330 watts =) 2500 watts. This is not the same as saying "13 amps" or even "13 amps at …
