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. WebFeb 2, 2024 · Done! The three-phase calculator shows you the values of other parameters: Phase current =5 A; Line voltage = 400 V; Phase angle = 33 deg; Power factor = 0.84; Apparent power = 5.96 kVA; and; Reactive power = 3.24 kvar.

WebNov 1, 2004 · You can calculate the phase current of a delta transformer winding by dividing the phase VA by the phase volts: I Phase = VA Phase ÷E Phase. The phase load in VA of a 3-phase, 240V load is the line load divided by three (one third of load on each winding). The phase load in VA of a single-phase 240V load is the line load (all on one … WebApr 1, 2008 · 3-Phase Calculations For 3-phase systems, we use the following equation: kW = (V × I × PF × 1.732) ÷ 1,000. Again, assuming unity PF and solving this equation for “I,” you get: I = 1,000kW ÷ 1.732V.
