Is there an example of how to connect the ADE7933 with current transformers?
I understand better now, I can also suggest the ADE7923, this is a non-isolated version of the ADE7933 with the same footprint and slightly different package (without increased creepage).
As for connecting the CT, it is very similar to using a shunt with the addition of a burden resistor. The input still should look like the diagram in the data sheet, with the 1kOhm and 33nF anti-aliasing filter.
Then a burden resistor value needs to be chosen based on the maximum current expected, the turns ratio of the CT and the full scale inputs to the current channel.
Once this burden value is found, I would recommend a center-tapped burden like the diagram above.
I replied here is this the same question?
