We are 3-phase 4w energy meter based on the ADE 7880
I Used CT Ratio - 2 : 2500
Single Burden resister = 39 Ohms(not used Tapped)
Voltage = 240 and I = 5A Fq =50 hz
VLEVEL = 5833666
CFxDEN = 1752
successfully get the Current, Voltage after Gain calibration and KW we got. but pules Error going totally out of range How to calculate CFxDEN . Please help me.
