7.15.2.2 Setting guidelines
GlobalBaseSel: Selects the global base value group used by the function to define (IBase),
(VBase) and (SBase).
Operation: With the parameter Operation the function can be set Enabled/Disabled.
Mode: The voltage and current used for the power measurement. The setting possibilities
are shown in table
14.
For reverse power applications PosSeq or Arone modes are strongly recommended.
