There are 4 time stages that can be set differently:
•
Dead time after 1-phase short circuits
•
Dead time after 2-phase short circuits
•
Dead time after 3-phase short circuits
•
Dead time for evolving faults
In this way, setting the parameter
Dead time aft.1ph. pickup
to
invalid
avoids an automatic
reclosing after 3-pole tripping due to 1-phase short circuits. This also applies to
Dead time aft.2ph.
pickup
and
Dead time aft.3ph. pickup
.
As soon as an evolving fault is recognized (see chapter
7.2.4.13 Evolving-Fault Detection During Dead Time
),
a separate dead time for faults begins with the stopping of the fault. The total dead time is composed of the
part of the dead time that expired until the evolving fault was stopped for the 1st disruption plus the dead
time for the evolving fault. With the setting of the
Dead time aft. evolv. fault
to
invalid
, no
other automatic reclosing cycle is executed after tripping through the evolving fault. The tripping through
evolving faults is then finished.
