Manual econ sens3 Version 3.0
“Phase check” installation test routine
The econ sens3 has a small installation test routine called “Phase check”.
Generally, it is assumed that all measuring coils were installed correctly and the measured load has a
power factor of > 0.71 (phase displacement between U and I < 45°). The measurement value table is
then displayed for the user as shown in Fig. 34.
If an error was made during installation, for example if the L2 coil was laid around the L1 conductor of
the voltage path, the power factor will fall below 0.71. A phase angle check can be performed by
pressing the “Phase check” button.
