QAre the RMS values with respect to V and I true RMS or calculated RMS?
AThe ADE7878 computes the true rms values. Please see ADE7878 rev F data sheet,
page 40. It explains that the ADE7878 computes exactly the expression 10, so
the rms calculation is a good one. As the bandwidth of the ADC measurements is
2kHz (see spec table at page9), signifies that the rms results contains all
harmonics up to 2kHz.
