Sorry if I offended you, it was certainly not my intention. As I wrote, my thoughts were exactly that: thoughts, based on (clearly wrong) attempt to visualise what is going on in the wires.
I trust you 100%, do not worry.
I guess the important thing to take into account is that we are facing a 3 vectors situation, with each wire being dephased from the others and not 3 parallels wires with the same phase; that is the hard part to visualise when you are not in the current theories knowledge (my case).
Some questions:
- for NUMSAMPLES, you suggest in our case (3-WIRES / 50 Hz) to use 45, correct (I ask because the default 36 value is a multiple of 6 as well, which is required for a 3-Wire installation).
- I guess the location of the vectors is important: how to determine what is L1, L2, L3 (with respect to the angles between each phase vector). Or the only important matter is to have the AC-AC Volts measure between one wire part of the CT measure and the third wire not part of the CT measure ?
