Dear Support,

We are using ADE7880, in which I can understand that I can read the below phase angles from **ANGLE0, ANGLE1, ANGLE2** registers using below combination of **ANGLESEL**

**Using ANGLESEL[1:0] = 00, I can measure below values: **

1. R Phase voltage-current phase angle

2. Y Phase voltage-current phase angle

3. B Phase voltage-current phase angle

**Using ANGLESEL[1:0] = 01, I can measure below values: **

4. R-Y Phase voltage-voltage phase angle

5. Y-B Phase voltage-voltage phase angle

6. B-R Phase voltage-voltage phase angle

**I have a doubt on how to read/derive the phase angles for the below combination:**

7. R-B Phase voltage-voltage phase angle

8. Y-R Phase voltage-voltage phase angle

9. B-Y Phase voltage-voltage phase angle

Also, please comment if all the above **9 angles** can be measured/read via ADE if the connection is 3P,4W and 3P3W.

Best Regards,

Anyone, Could you please reply ?
