I am trying to use a Venus device along with a Carlo Gavazzi CT meter to measure individual 3 phase import and export and am getting odd readings.
I cannot wire the carlo gavazzi into each phase because there is not space to do so.. so I have just bridged one phase across all three for the referenc voltage on the carlo gavazzi - I think this may be throwing the readings out (e.g. one phase always seems to read the opposite direction). Is this becasue it isnt seeing the 400V Line to Line boltage? I thought it might work like this in any case - but Im not sure exactly how the meter and Venus measure and display the values.
If this is the reason - is there any way to get around this without wiring into each individual phase?
Any idea smore than welcome!
