I'm away from my project again for a few days, but I managed to quickly connect one cable before I left. I managed to connect one CT sensor and now I see that this channel even shows some Amp consumption on Current_1.
But same channel Power and Energy = 0 ?
Do I understand correctly that since I don't have L1 and N1 attached, it won't be able to calculate power and energy data?
And If I'm right, then since I have three-phase current (380V), I have to connect each phase separately, i.e. L1, L2 and L3
and in turn, since I have three different phases, it would be most correct to measure the devices that are behind the first phase in the first part and the devices that are behind the second phase in the second part, then the calculation will be most accurate, although at the same time the differences in phase currents are minimal, i.e. 0.0x Volts, it does not make much difference which phase is behind which sector to measure
