I have a question regardign the sign of reactive power..
I have made some final tests, all looks fine, but one thing I do get confused about...
When I apply a signal with a "lagging" current waveform, I would expect a negative Q, and when applying a waveform with a leading current waveform, i would expect a positive Q, but the read-outs from the ADE7878 are quite opposite..
I have made some drawings and a screen dump of my scope, while adding the leading and lagging waveform. This one is attached.
Could You please help me, what I am missing here? (Sorry for the newbee question :-))
Kind regards, Lars Ulrik Hune
