3-phase power consumption measurement

[BartButenaers]

@Paul-Reed

Ah Ok, you are measuring 3 circuits, each being on 3 phase

Yes, something like this:

I have only showed the measurements of devices on phase L3, but of course on the other phases the same happens. But then my drawing becomes unreadable, and I am running out of time for tonight

P.S. I have removed the short circuit you mention. Was indeed just a line drawed to quickly...
