Fundamental power factor of phase (i+1) or cosine of the angle of the phase-to-neutral voltage fundamental of phase (i+1) with
respect to the current fundamental of phase (i+1) with i ∈ [0; 2]
Note: The fundamental power factor is also called the displacement factor.
Tangent of phase (i+1) or tangent of the angle of the phase-to-neutral voltage fundamental of phase (i+1) with respect to the cur-
rent fundamental of phase (i+1) with i ∈ [0; 2]
