I am working with an ADE7880 and set to 3-phase, 4 wire configuration. I set to use the Regular accumulation mode.
Here is the settings is 50Hz and 240, 100 meter
CT turns ratio = 1:5000 = 1/5000 = 0.0002
Burden = 13.2 ohms , ADE fs I/P(V) = 0.5 volt
Voltage divider = 1096k = 1096000
Ifs = 0.5 fs *ct ratio/(R1+R2 x1.414) = 133.9 A
Like that Ufs = 387.8 v
Vn = 240 v
Based on above value i calculate VLEVEL = 6464134
WTHR = ?
Now i set WTHR = VARTHR = VATHR value = 0x03(default value) like that
LCYCMODE = 0x40
MC = 1600 and n= -3 (fixed it) n - how calculate it ?
COMPMODE = 0x3FF
I successfully get the Current, Voltage, V = 238.7 ,I = 2 ams and But when PF = 1 i Read watt value from reg. xWATTHR = 535 and PF = 0.5 watt value xWATTHR= 170 like that is correct value? Please help me ?
