Abstract
In the three-phase circuit at sinusoidal mode a constant and variable components of the vectorial instantaneous power (IP) define two new integrated powers: the power imbalance vector and the non-pulsed power vector. Together with the standard scalar powers of sinusoidal mode (the standard complex power and the complex pulsation power), these two vectorial powers determine power equation of unbalanced mode and pulsing mode. It is shown that under asymmetrical voltage the vectorial MM is zero only if the standard reactive power and the power imbalance equal to zero. The power factor is equal to unity.
