2.3.2 Extended AR open
time, shot 1
By setting the Extended t1 parameter (On/Off), this function can either
be selected or not. The purpose is to adapt the length of the AR Open
time to the possibility of non-simultaneous tripping at the two line ends.
If a permissive communication scheme is used, and the permissive com-
munication channel (for example, PLC, power-line carrier) is out of serv-
ice at the fault, there is a risk of sequential, non-simultaneous tripping.
To ensure a sufficient line dead time, the AR open time is extended by
0,4 s. The input signal AR01-PLCLOST is checked at tripping. See Fig.
4.
2.3.3 Long trip signal
Under normal circumstances the trip command resets quickly, due to fault
clearing. You can set a maximum trip pulse duration by tTrip. At a longer
trip signal, the AR open dead time is extended by Extend_t1. If the
Extended t1 = Off, a long trip signal interrupts the reclosing sequence in
the same way as AR01-INHIBIT.
2.3.4 Reclosing programs
Select these reclosing programs to fit the application:
3ph
3-phase reclosing, 1 shot
2*3ph
3-phase reclosing, 2 shots
3*3ph
3-phase reclosing, 3 shots
4*3ph
3-phase reclosing, 4 shots
1ph
1-phase reclosing, 1 shot
1/3ph
1-phase or 3-phase reclosing, 1 shot
1ph + 3ph
1-phase followed by 3-phase reclosing, or just one 3-
phase reclosing depending on fault
1/3ph + 3ph
1-phase or 3-phase reclosing, followed by 3-phase
reclosing, 2 shots
2.3.4.1 1/3ph reclosing
One-shot reclosing is used as an example of the operation for single-phase
or three-phase. See Figures 3, 5, and 8. Here, the AR function is assumed
On and Ready. The breaker is closed and charged.
AR01-START is received and sealed-in at operation of the line protec-
tion. The AR01-READY output is reset (Ready for a new AR cycle).
If the AR01-TPTRIP (three-phase trip) is...
low,
the timer for single-phase reclosing open time t1S is started and
the AR01-SP1 output (auto-reclosing single-phase, shot 1, in
progress) is activated.
It can be used to suppress Pole disagreement and Earth-fault pro-
tection during the single-phase open interval.
