GlobalBaseSel : Selects the global base value group used by the function to define ( IBase ),
(
UBase ) and ( SBase ).
Operation : With the parameter Operation the function can be set On / Off .
Mode : The voltage and current used for the power measurement. The setting possibilities are
shown in table 22.

The function has two stages that can be set independently.
With the parameter OpMode1(2) the function can be set On / Off .
The function gives trip if the power component in the direction defined by the setting
Angle1(2) is larger than the set pick up power value Power1(2)
