The setting

Power1(2)

gives the power component pick up value in the

Angle1(2)

direction. The setting is given in p.u. of the generator rated power, see equation

Minimum recommended setting is 1.0% of S

(Equation 79)

The setting

Angle1(2)

gives the characteristic angle giving maximum sensitivity of the

power protection function. The setting is given in degrees. For active power the set angle
should be 0° or 180°. 0° should be used for generator low forward active power protection.
