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 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 PICKUP1 signal, pickup of stage 1, is activated.
5. Increase the current to 100% of IBase.
6. Switch the current off and measure the time for activation of TRIP1, trip of stage 1.
7. If a second stage is used, repeat steps
