單相接地跳閘和重合閘故障（單相死區時間），相位故障無重合閘
1.1P-3P單相跳閘后接三相約20 ms后跳閘，接地故障的三相重合閘（三相由單相跳閘啟動的死區時間），
三相故障無重合閘1.接地1P3P-3P三相跳閘和重合閘和相位故障（三相死區時間）
1.1P3P-1P3P單相接地跳閘和重合閘故障（單相死區時間）、三相跳閘和相故障重合閘（三相死區時間）
外部選擇：通過二進制輸入進行外部選擇1P_ 1P、MD1_，
MD1_EXT_1P3P_3P和自最后一次重合閘嘗試下降沿起的MD1_EX_1P3P_1P3周期（CB恢復時間），在此期間，自動重合閘功能為被阻止，之后該功能被重置。
如果歧視和死區時間，一段時間從另一段時間的瞬間開始兩次之間發生的跳閘。
如果保護在以下情況下跳閘，回收計時器也會啟動：故障持續時間“t Oper”已過。條件阻塞信號的I/P。
阻塞僅在AR循環未進行時發生。
如果不需要，則設置為“off”（“F”或“False”）。當跳閘由距離保護SOTF邏輯或方向E/F PLC信號，相應的信號可以連接到該I/P以防止自動重合閘。手動關閉阻止由手動斷路器關閉信號激勵的I/P。
即使是正在進行的自動重合閘循環也會立即被施加到該輸入的信號阻止。
如果不需要，則設置為“off”（“F”或“False”）。抑制Inp。
I/P，用于在冗余狀態下阻止跟隨器重合閘功能
計劃從主對象的末端阻止跟隨器關閉信號，直到回收時間結束。
如果不需要，則設置為“off”（“F”或“False”）。擴展t1
有條件延長死區時間的輸入（單和三相）用于第一次（快速）重合閘。
如果不需要，則設置為“off”（“F”或“False”）。
single-phase trip and reclosure for earth
faults (single-phase dead time), no reclosure for phase faults
1. 1P-3P single-phase trip followed by three phase
trip after approx. 20 ms, three-phase reclosure for earth faults (three-phase
dead time initiated by single-phase trip),
no reclosure for -phase faults
1. 1P3P-3P three-phase trip and reclosure for earth
and phase faults (three-phase dead time)
1. 1P3P-1P3P single-phase trip and reclosure for earth
faults (single-phase dead time), threephase trip and reclosure for phase faults
(three-phase dead time)
Ext.Selection External selection by the binary inputs
MD1_EXT_1P_1P, MD1_EXT_1P_3P,
MD1_EXT_1P3P_3P and
MD1_EX_1P3P_1P3PPeriod (CB recovery time) from the falling edge of the last reclosure attempt during which the autoreclosure function is
blocked and after which the function is reset.
In the event of an evolving fault between discrimination and
dead times, the period commences at the instant of another
trip occurring between the two times.
The reclaim timer is also started if the protection trips after
the fault duration time ‘t Oper’ has elapsed.I/P for a conditional blocking signal.
Blocking only takes place providing an AR cycle is not in progress.
Set to ‘off’ (‘F’ or ‘False’), if not needed.
When tripping is by the distance protection SOTF logic or a
directional E/F PLC signal, the corresponding signals can be
connected to this I/P to prevent auto-reclosure.
Manual Close
Blocking I/P excited by the manual CB close signal.
Even an autoreclosure cycle that is in progress is immediately blocked by a signal applied to this input.
Set to ‘off’ (‘F’ or ‘False’), if not needed.
Inhibit Inp.
I/P for blocking the follower reclosure function in a redundant
scheme. The follower is blocked from the end of the master
closing signal until the end of the reclaim time.
Set to ‘off’ (‘F’ or ‘False’), if not needed.
Extend t1
Input for conditionally extending the dead time (single and
three-phase) for the first (fast) reclosure.
Set to ‘off’ (‘F’ or ‘False’), if not needed.
