This is done with a speed so that the final impedance is reached after 1 second. As the
injected voltage is lower than 0.92
addition to this the signal ZONE1 should be activated.
5. Set
Now the signals TRIP1 and TRIP should be activated.
6. With reduced amplitude of the injected voltage to 0.8
angle is changed via ZC + (ZA – ZC)/2 to a value corresponding to half
between the injected current and voltage.
This is done with a speed so that the final impedance is reached after 1s. As the injected
voltage is lower than 0.92
the signal ZONE2 should be activated.
7. Set
Now the signals TRIP2 and TRIP should be activated.
