2. Adjust the injected current and voltage to the set values in % of IBase and UBase
(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
power protection). Check that the monitored active power is equal to 100% of
rated power and that the reactive power is equal to 0% of rated power.
3. Change the angle between the injected current and voltage to Angle1 + 90°.
Check that the monitored active power is equal to 0% of rated power and that the
reactive power is equal to 100% of rated power.
4. Change the angle between the injected current and voltage back to 0°. Decrease
the current slowly until the START1 signal, start of stage 1, is activated.
