Re: Using CT with ADE7758

Hi dlath,

Thanks for the reply.

I am working with 2500:1 CT, But in case if we want to make use of 100/5, then what are the things need to be taken care?

 

This schematic I have taken from standard circuits as per applications notes of Analog. I think AVDD & DVDD can be shorted but they application notes state that AGND & DGND should be separated with choke or inductor to avoid noise on digital side. Even general theory also say that digital & analog grounds should be connected at a single point. Here in schematic they have been connected at a single point using choke.

Still I would try with your suggestion.

 

Please excuse here for my mis printing. These values are for AIRMS register with load on & load off. Above readings are with AIRMSOS=0.

 

With Regards,

Krunal
