Any one please help me to do this.


I am using ADE7878 for 3phase energy meter purpose. Now, from the previous threads I have read the values from the VRMS registers.

I designed a voltage divider for three pahse input with input-400V & output - 0.35V(rms).  Please find the attached Excel sheet of my applied voltage & VRMS register value. Please explain me to correct this values to get exact voltage value as actual.


Please guide me to do this.. Awaiting for the replies.
