Q(P
tan
φ
(fix)) procedure
In this procedure the reactive power Q is used as control value.
Here the reactive power is set according to the power fed in by recording the active
power P at the grid connection point by the selected measuring device and transferring
the measurements to the data logger. The logger assigns the control value Q to the
relevant power via tan
φ

This procedure requires a power quality analyzer that has been
connected to the data logger and configured.
