Setting guidelines

GlobalBaseSel: Selects the global base value group used by the function to define IBase, VBase and
SBase. Note that this function will only use IBase .
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 20.

The function has two stages that can be set independently.
With the parameter OpMode1(2) the function can be set Enabled/Disabled.
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)
