Long trip signal

In normal circumstances the trip command resets quickly because of fault clearance. The user
can set a maximum trip pulse duration
the reclosing sequence in the same way as a signal to input INHIBIT. If
trip time inhibit is disabled and

Maximum number of reclosing shots

The maximum number of reclosing shots in an auto-reclosing cycle is selected by the setting
parameter
parameter
include some single-phase or two-phase reclosing. Usually there is no two-phase tripping
arranged, and then there will be no two-phase reclosing.
The decision for single and 3 phase trip is also made in the tripping logic (SMPTTRC) function
block where the setting

ARMode = 3ph, (normal setting for a single 3 phase shot)

12.2.2.8
3-phase reclosing, one to five shots according to setting
three-phase trip PREP3P is always set (high). A trip operation is made as a three-phase trip at
all types of fault. The reclosing is as a three-phase Reclosing as in mode 1/2/3ph described
below. All signals, blockings, inhibits, timers, requirements and so on. are the same as in the
example described below.

ARMode = 1/2/3ph

12.2.2.9
1-phase, 2-phase or 3-phase reclosing first shot, followed by 3-phase reclosing shots, if
selected. Here, the auto-reclosing function is assumed to be "On" and "Ready". The breaker is
closed and the operation gear ready (operating energy stored). Input START (or STARTHS) is
received and sealed-in. The output READY is reset (set to false). Output ACTIVE is set.
• If inputs TR2P is low and TR3P is low (1-phase trip): The timer for 1-phase reclosing open
time is started and the output 1PT1 (1-phase reclosing in progress) is activated. It can be
used to suppress pole disagreement and earth-fault protection trip during the 1-phase
open interval.
• If TR2P is high and TR3P is low (2-phase trip): The timer for 2-phase reclosing open time is
started and the output 2PT1 (2-phase reclosing in progress) is activated.
• If TR3P is high (3-phase trip): The timer for 3-phase auto-reclosing open time,
started and output 3PT1 (3-phase auto-reclosing shot 1 in progress) is set.
• If STARTHS is high (3-phase trip): The timer for 3-phase auto-reclosing open time, t1
3PhHS is started and output 3PT1 (3-phase auto-reclosing shot 1 in progress) is set.
While any of the auto-reclosing open time timers are running, the output INPROGR is activated.
When the "open time" timer runs out, the respective internal signal is transmitted to the
output module for further checks and to issue a closing command to the circuit breaker.
When a CB closing command is issued the output prepare 3-phase trip is set. When issuing a
CB closing command a "reclaim" timer
that time the auto-reclosing function resets to the "Ready" state and the signal ACTIVE resets.
If the first reclosing shot fails, a 3-phase trip will be initiated and 3-phase reclosing can follow,
if selected.
