I am use 2500:1 CT.
What are the configuration needs to be done for phase calibration.
Please provide the procedure for doing phase calibration for ADE7880.
THe ADE7880 Calibration Application Note is a great resource, http://www.analog.com/media/en/technical-documentation/application-notes/AN-1171.pdf. On page 12, the phase calibration procedure is outlined.
The equation here has a small error in sign, the numerator of the degree error equation is off and should be:
Then after finding the degree error, the actual APHCAL value can be calculated and then applied to the APHCAL register.
Let me know if you want me to go into more details.
