ADE7816 Power factor Measurment

Question asked by Ramesh@146 on Dec 21, 2017

We are doing Testings with ADE7816 Energy metering IC

Following parameters need be measured

1. Vrms
2. Irms
3.Frequency
4.Active Power
5.Reactive Power
6.Power factor

while testing with Power Factor above 0.9 we are getting above values near to Actual values with some error which can be calibrated.

But for Power Factor around 0.6  reactive Power and Power factor ( deriving from Phase angle)  are not showing correct values and parameters were dynamically changing.


We have following queries

1.Whether this IC  is suitable  for measuring at any power factor  ?

2. If so is there any specific configuration to be done please suggest ?

3.It is given in datasheet " Power factor does not take into account the effect of any harmonics ". Is not considering
harmonics is the reason for wrong values of Reactive Power and Power factor we are getting?

Please suggest is there any way to solve this problem ?
