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.
