...and it's only by taking into account the phase of the voltage that the real (i.e. non reactive) power is calculated?
Well, no.
It doesn't need to take into account the phase of the voltage specifically. When you mutiply the instantaneous amperage and voltage, you get real power exactly...
Thank you for the reply but I don't think it really answered my question, and I'm sorry if I didn't make my question clear. What I am asking is whether the current transformer generates flux from the part of the current that is out of phase with the voltage, and if it doesn't then why doesn't it...
Apparently my modern electronic home electric meter uses a 'current transformer' to measure the current in order to calculate the wattage I am using.
My question: is the flux generated in the current transformer also proportional to the reactive part of the current as well as the in-phase...
