2. Adjust the injected current and voltage to the set values in % of IBase and VBase
(converted to secondary current and voltage). The angle between the injected
current and voltage shall be set equal to the set direction Angle1, angle for stage 1
(equal to 0° for low forward power protection and equal to 180° for reverse
