15.2.7 Operation principle
GUID-4A46757C-EC5D-4BCE-9D09-C8152B062CE1 v3
The instantaneous output values of active and reactive power from the
Measurements function CVMMXN are used and integrated over a selected time
tEnergy to measure the integrated energy. Figure
328 shows the overall
functionality of the energy calculation and demand handling function ETPMMTR.
