Definition

quantity given by the product of voltage phasor $\underset{̲}{U}$ (voltage phasor) and the complex conjugate of the electric current phasor $\underset{̲}{I}$ (electric current phasor):

\underset{̲}{S} = \underset{̲}{U} \underset{̲}{I}

grandeur donnée par le produit du phaseur de tension électrique $\underset{̲}{U}$ (voltage phasor) et du conjugué complexe du phaseur de courant électrique $\underset{̲}{I}$ (electric current phasor);

\underset{̲}{S} = \underset{̲}{U} \underset{̲}{I}

Notes

\underset{̲}{S} = P + j Q

where $P$ is active power (active power) and $Q$ is reactive power (reactive power)

See IEC 60050-131,locality:item="131-11-39".

\underset{̲}{S} = P + j Q

où $P$ est la puissance active (active power) et $Q$ est la puissance réactive (reactive power).
