Now i am using ade7878 and can get the voltage and current,according to my circuit the Vfs = 884,Ifs = 35 and then WTHR = 33516139*8000*3600*10^-3/Vfs/Ifs = 0X1D721F1.I want to get the three phase active power and reactive power.But i see the datasheet,i did`t find any register to get value,only instantaneous values.The power values that i read AWATT register is it actual value,or should i make a translate.look forward to somebody can tell me .
