2. Adjust the injected current and voltage to the set values in % of
to secondary current and voltage). The angle between the injected current and voltage shall
be set equal to the set direction
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
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
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
