How do you know if you have 3 phase power
WebMar 1, 2009 · phase 3 apparent power = 82 x 230 = 18,860 VA = 18.86 kVA Total three phase power = 18.4 + 16.1 + 18.86 = 53.36 kVA Similarly given the power in each phase you could easily find the phase currents. If you also know the power factor you can convert between kVA and kW as shown earlier. Unbalanced Voltages WebA three-phase power supply delivers power at a steady, constant rate. Comparing single-phase vs. three-phase power, three-phase power supplies are more efficient. A three-phase power supply can transmit three times …
