Apparent power: components and physical interpretation

This study explains the basic attributes as well as the physical properties of the apparent power S. The apparent power is divided in active and nonactive powers. It is shown that all forms of nonactive power have a common form of manifestation, parasitic oscillations of energy among electrical components and electromechanical, electrochemical, or electrothermal systems. The main conclusion of this paper is summarized in a recommendation to incorporate all the nonactive powers, except the fundamental one, in one entity
