ADE7763 Negative Active Power Measurement

Hi All,

In my project the aim is measurement of Positive and Negative Active Power.

So I calibrated the device with current flowing in one verse, that give me Positive Active Power.

I tested with a reference power meter and ADE7763 measures are good.

 

 

But, when I switch source and load (so the current verse change), measurement are not right, anymore

 

 

I tried with many ADE7763, different circuits, with CT or Shunt, but the scenario is always the same.

 

 

Could you explain me why this happen?

 

 

Thank you.

Kind Regards.

AlessandroMorgan
