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.
