Power Quality Analyzer Model 8335
Displacement 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].
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 current fundamental of phase (i+1)
with i
∈
[0 ; 2].
