cos
φ
(U) procedure
In this procedure the cos
φ
displacement factor is used as control value.
By changing the displacement factor, it is possible to influence the voltage at the grid
connection point by recording the voltage U at the grid connection point by the
selected measuring device and transferring the results to the data logger. The logger
then assigns the cos
φ
control value to the relevant power using for example a two-
point characteristic curve.
Depending on the selected characteristic curve type, value pairs (interpolation points)
and the associated excitation types per interpolation point are needed in order to
produce the characteristic curve (line) for this procedure.
