This is done with a speed so that the final impedance is reached after 1s. As
the injected voltage is lower than 0.92 UBase the STAR
T signal should be
activated. In addition to this the signal ZONE2 should be activated.
7. Set N2Limit to 1 and repeat step
6.
Now the signals TRIP2 and TRIP should be activated.
