Hi Hmani
I red the an-1171 its a good note but i have 3 questions regarding the 4 equation at the beginning of page 11 in an-1171
q1- what is the VRMS[LSB] and IRMS[LSB] mentioned in two eqations
V constant [V/LSB] = Voltage Input [V]
VRMS[LSB]
I constant [Amps/LSB] = Current Input [A]
IRMS[LSB]
q2 - registers xVGAIN and xIGAIN are they only used to register the channel gain or the contents are used by the ADE7880 to make power calculations ?
q3 - Voltage input is it the 220v ac or the 0.219780v ac from the voltage divider witch is 1Mohm and 1Kohm also Current input is it the 10amps that are consumed by the load or 0.005amps the output of the current transformer with the CTratio of 2000:1?
best regards
Current
