I have a 3-phase system with an unbalanced delta load, as seen in the figure below.
I want to measure the total apparent and active power consumption and if possible, the respective power consumption for each of the phases, but I am a bit confused.
I am using a 3-phase equipment from National Instruments which shows that Vc = 380V, Vb = 380V and Vc = 0V. I assume that because of the absent neutral, it uses phase A as a reference, thus Vc = Vca, Vb = Vba.
I am also measuring all three line currents.
What is the total apparent power equation? I am aware of Blondel's Theorem, but it is valid only when measuring instant power right?
Also, is it possible to measure the power of each separate phase?
