hysteresis
4 point with hysteresis
Curve with 4 interpolation points with hysteresis
Interpolation point P1 to P4
Interpolation points 1 to 4 for the curve
x: P/P
AV
P/P
AV
ratio of the individual interpolation points
y: cos
ϕ
excitation
Displacement factor control value for the individual
interpolation points (incl. excitation type)
Hysteresis P
Hyst
Hysteresis of the curve as the P/P
AV
ratio
This procedure requires a power quality analyzer that has been connected
to the data logger and configured.
