Energy Meter VM-3P75CT Leistungsfaktor stimmt nicht

Hi @DStuder, I think you are referring to the negative value (-0.974) of the power factor correct? This is the result of the power factor convention used in the VM-3P75CT.

Hi @phaseshifter and @BartChampagne, the VM-3P75CT uses the IEEE sign convention for its reported power factor. The sign of the power factor in combination with the sign of the real power indicates in which quadrant the system is operating, and thus if the system is nominally capacitive or inductive.

The negative power factor in combination with the negative total power tells us that the system is slightly inductive. If the installation isn’t actually exporting power to the grid, then the CTs are flipped (for the grid role: negative power is exporting, positive power is importing).
