Abstract :
This paper discuses the properties of negative-sequence active power stream relative to the point of measurement in the unbalanced three-phase electric circuit. Analysis of the negative-sequence active power stream for the typical circuit asymmetry cases is carried out. It was shown that the stream direction can be used as an unbalance source index.
