First, select the type of calculation. To calculate the power and load from known voltage and current, select the load connection (star or delta) and enter the voltage (line OR phase), current (line OR phase), and power factor. Click or tap the Calculate button. The power and the load...
Let’s say you have a voltage, a total power in kilowatts (kW) and a power factor, and you want to know the current (in amps, A) in the circuit. Re-arranging the power calculation formula above gives: I = P / (√3 × pf × V) If your power is in kilowatts (i.e....
Select the symmetrical sequence used in the power calculation using theSequenceparameter: Positive: VkejθVk=Vk+ejθVk+, IkejθIk=Ik+ejθIk+ Negative: VkejθVk=Vk−ejθVk−, IkejθIk=Ik−ejθIk− Zero: VkejθVk=Vk0ejθVk0, IkejθIk=Ik0ejθIk0 ...
