How to calculate AC power I now have a voltage of 90a at 400 / 3 / 50. What is the power? This is AC, not DC How to calculate the single-phase 220 V?
Three phase AC circuit power P = √ 3 × UL × IL × cos φ; Cos φ is the power factor, if the power factor is unknown, it can be selected by 0.8
P=√3×400×90×0.8=49.8816KW
When calculating the power of the circuit, it is the same as the frequency of the power supply, so the number of 50 is not needed
