in the https://www.analog.com/media/en/technical-documentation/user-guides/ev-ade9000shieldz-ug-1170.pdf at page 3 it's written that it's possible to use voltage output CTs, simply removing the burden resistors.
I was considering to replace the CTs with 0.333V voltage output CTs to avoid the CT open circuit potential risks.
I see in some posts you confirm that the 0.333V CTs are supported RE: ADE9078ACPZ 0.333V TC
Anyway from this and other posts RE: Regarding current transformer in ade9000 I see that in this case it's recommended to connect one of the CT's leg to GND to avoid common mode issues.
For my understanding this is the required change in the single-ended case, where Rb is the single burden resistor (embedded in the CT):
In other posts I see that the single burden is not suggested: RE: CT burden connection so there are no clear indications about this setup.
Could you please confirm that the voltage output CTs setup it's supported, that the provided change to the CT connection in the schematic is required and what are the other implications of this setup (if any)?
I would like to understand if it's worthy to proceed in this direction.
