Some features of the instantaneous active and reactive powers p and q , not reported earlier, are discussed in this paper. It is shown that oscillating components and of these powers may not depend on the order of the load current harmonic. It was shown, moreover, that a load supplied with a nonsinusoidal voltage may not be distinguished in terms of p and q powers from a harmonics generating load (HGL) supplied with a sinusoidal voltage. This observation is important for compensator control. Also it was shown that the instantaneous reactive power q cannot be interpreted as a measure of amount of energy exchanged between supply lines of a load or as amount of energy rotating around such lines, as it was suggested in some publications on the IRP p-q Theory. A phenomenon of energy rotation or exchange between lines does not exist.
