GlobalBaseSel : Selects the global base value group used by the function to define
IBase , UBase and SBase as applicable.
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 40 .

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 smaller than the set pick up power value Power1(2)
