ADE7880 - Inverted Signal for Active Power/Energy

Question asked by carlos.affonso on Nov 8, 2016

We are facing some strange behaviors using ADE7880:

 

We are applying  the follow signals on meter:

 

- 240V;

- 5 A;

- angle V-I = 60 o.;

 

We are getting the following values:

 

Active = -1800W

Reactive = +3117 var

 

Changing the quadrant :

 

- 240V;

- 5 A;

- angle V-I = 120 o.;

 

Active = +1800W

Reactive = +3117 var

 

The other registers values (instead of active power/energy) seems to be OK.

 

The Internal ADE7880 Registers :

   Can you help us to figure out what could be wrong?
