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°. 180° should be used for generator reverse power protection in 50Hz
network while -179.5° should be used for generator reverse power protection in 60Hz
network. This angle adjustment in 60Hz networks will improve accuracy of the power
function.
