1/ My question is about the ground in the phase why ? is it possible to not connect the phase to the ground ?
2/ in eval board R2=R9=150k but in the datasheet (test circuit ) R1=R2=150ohm why??
For Question Number 1: No, you have to connect the Phase to the Ground because this will become your reference ground to the chip ADE9153A. IN single phase meteringFor Question Number 2: PLease use the 150k in the schematic of the user guide and not the 150 of the test circuit. Thank you
but from the phase i will connect in ac/dc convertor ? in this way will connect to the ground !!!
