for low frequencies, above some frequence (few Hz probably) it could be detected even if it is not harmonics. Normally harmonics are important because this is the only possible frequency generated by passive components... subharmonics, or non synchronous frequency appear on the scope display, as instabilities... anyway if the voltage is pure fundamental sinus (without DC offset), no current harmonics, no DC current, no harmonics, no subharmonics, no asynchronous frequency, can transport current.
if the voltage is a little deformed, harmonics may transport a little power, but the job of the powermeter is to measure it precisely. If voltage and current are crazy, but in the allowed bandwidth, the power meter can measure the power without problem. That is it's job... if AC voltage is triangular (I've seen it with college PC labs and exhausted transformers) and current is big asynchronous pulse or submodulation (switching device in bad mood) of few hundred Hz or few Hz, no problems... if there is DC offset, only a DC current can transport energy, beside the usual AC energy. 2013/6/11 Alan Fletcher <[email protected]> > > From: "Alain Sepeda" <[email protected]> > > Sent: Monday, June 10, 2013 11:07:52 AM > > > the model of the current clamps should be documented (maybe I missed > > it). > > It have some impact on PCE-830 performance on various measures > > (power, harmonics...) > > They used voltage to determine there is no DC component.
