Voltage reading in delta 3-wire configuration for ADE7880

Good morning,

 

I am trying to do a reading of the voltages of a three-phase, 3-wire delta configuration with an ADE7880.

 

As it is indicated in the data sheet, I have defined the CONSEL bits as 01, so the lecture of the phase B will be the difference between phase A and phase C.

 

Also, the connections are:

 

-Phase A connected to VA.

 

-Phase B connected to VN.

 

-Phase C connected to VC.

 

My question is, with this configuration, what is the expected readings of the voltages?

 

I am obtaining three sinusoidal signals with a difference of 60º each, but shall it not be 120º of difference? Am I doing something wrong?

 

Thank you.
