Question asked by TomMitchell on Jan 9, 2014

I use the ADE7878E evaluation board + Labview software


Eventually I have managed to get the currentRMS & VoltageRMS readout good.

AIRMS = 488804 (0,488A)

VRMS = 2315222 (231V)


I still have problems to get correct values for the power measurements.

When using Line Accumulation Mode xWATTHR,xVARHR are the same and have a value of 400. (positive & negative). – LINECYC value is 10.

These values do not changes when adding a new or removing a device to measure.


Can somebody help me to get correct values for power measurement.
