The kw in your formula is the three phase kw so i think you should be using 746 not 249.
Three phase electric power formulas.
Three phase electric power v i 1 732 pf where v voltage i current pf power factor 0 8 three phase electric power calculation is made easier here using this online electrical calculator.
Electrical electrical units amps and electrical wiring wire gauge and awg electrical formulas and motors.
I m not sure if this helpful but i will derive the formulae using the above method so you can see the two tie together.
You can easily find electric power in watts by using the following power formulas in electric circuits.
Power formulas in dc ac single phase and ac three phase circuits.
That said there isn t much extra you have to do when working with three phase power equations so you ll be able to solve whatever three phase.
Three phase power is a widely used method for generating and transmitting electricity but the calculations you ll need to perform are a little more complicated than for single phase systems.
It is a type of polyphase system and is the most common method used by electrical grids worldwide to transfer power.
Ac active reactive and apparent power real imaginary and apparent power consumption in ac circuits.
Ac circuit voltage current and power in an ac circuit alternating current is generated from a sinusoidal.
It is also used to power large motors and other heavy loads.
Power 3 phase kw therefore per phase kw 3 kva per phase kw per phase power factor kw 3 x pf phase voltage vll 3.
