ADE7753 Test Circuit

Hello everybody

 

I want to make a test circuit for measurement using ADE7753. I want to use a current transformer and a AC/AC voltage transformer as transducers. Using available designs I have created a schematic and I am going to put together a PCB and test it. But before I do it I would like to share it here so if someone sees something wrong they would tell me - I really want to get this working from the first trial.

 

I am going to power the ADE7753 from a microcontroller circuit - perhaps an Arduino to get it running initially. Since it is isolated from the power supply, I believe this will not be a problem? Also my analog ground will be the neutral output of the voltage transformer; it will also be connected to the mcu ground. I do not know if this is a good design, so this is why I am posting here.

 

Please take a look and let me know if there is something I need to change. Thanks a lot
