That is, when the trigger is activated, the GE will wait until phase U voltage reaches 0 V. Once
0V
U
are reached, then GE will wait until phase U reaches angle β (Fault delay). At this point, the
specified fault will start. The first image above shows how the GE waits
β
= 0º, so the defect
starts immediately. The second image the GE waits
β
= 90º (always in phase U) and then the
defect starts.
At the same time the fault starts, one digital output generates a signal that will remain activated
until the fault finishes.
