Symbol: P
Definition: for a polyphase line mean value, taken over one period, of the instantaneous power

NOTE – For a three-phase line under symmetric and sinusoidal conditions, the active power is P=UI 3 cosϕ MathType@MTEF@5@5@+=feaagCart1ev2aaatCvAUfeBSjuyZL2yd9gzLbvyNv2CaerbuLwBLnhiov2DGi1BTfMBaeXatLxBI9gBaerbbjxAHXgarqqtubsr4rNCHbGeaGqipG0dh9qqWrVepG0dbbL8F4rqqrVepeea0xe9LqFf0xc9q8qqaqFn0lXdHiVcFbIOFHK8Feea0dXdar=Jb9hs0dXdHuk9fr=xfr=xfrpeWZqaaeaabiGaciaacaqabmaacaqaaqaaaOqaaiaadcfacqGH9aqpcaWGvbGaamysamaakaaabaGaaG4maaWcbeaakiGacogacaGGVbGaai4Caiabew9aMbaa@3E46@ , where U is the RMS value of any line-to-line voltage, I is the RMS value of any line current and ϕ is the displacement angle between any line-to-neutral voltage and the corresponding line current.
