I am using ADE7758 for energy measurement using Line accumulation.
what is the expected value of APCFDEN ?
How should we select the range of voltage and current ?
Now i am taking voltage full scale -500 V and current 40A, after calculating APCFDEN comes to be 900.
My set up is having following values.
voltage - 233V, current- 3.96A, 50Hz and Power factor=1.
In LINECYC i have stored 600(Dec), Accumalation time = 5.99.
I am using only one phase for calculation.
After 6 sec if i read Watthr register i got 11635d, and based on equations 60 and 61 i calculated expected value, it comes to be 17695d.
What are the typical values of xWG ?
where am i doing wrong ?
what steps to be followed in offset calculation ? can i select same LINECYC for both Itest and Imin ?
