De-energised line ‘Dead Line’ (‘Dead Line 2’) with checking
of synchronism ‘synchroChck’ (‘synchroChck2’)
Before the ‘Close CB’ (or ‘Close CB2’) instruction can be issued,
either the ‘Dead line’ or the ‘synchroChck’ I/P (or ‘Dead line 2’ or
‘synchroChck2’ in a duplex scheme) must be at logical ‘1’.
Logic: [(‘synchroChck’ AND ‘CO ready’) OR ‘Dead Line’ OR
‘ExtSCBypas']
Logic: [(‘synchroChck2’ AND ‘CO ready 2’) OR ‘Dead Line 2’ OR
‘ExtSCBypas']
External blocking ‘ExtBlkAR’ and ‘CondBlkAR'
The reclosure function is always blocked by an active ‘ExtBlkAR’
I/P.
An active ‘CondBlkAR’ I/P will only block the function, providing
a reclosure cycle is not running (i.e. the ‘AR in prog.’ signal is at
logical ‘0’).
The ‘Cond.Blk AR’ signal is needed to prevent a reclosure cycle,
when no reclosure is wanted for a first trip that occurs during ‘t
Oper’. This is the case, for example, for trips by the switch-ontofault (SOTF) protection or by a directional E/F protection via
PLC.To prevent the SOFT from initiating auto-reclosure, the distance
protection ‘SOFT start’ signal must be connected to the
‘CondBlkAR’ input.
'Manual close'
The reclosure function is immediately blocked (for the blocking
time ‘t AR Block’) by a ‘Manual close’ signal. This signal is also
needed for the overreaching logic to switch the ‘ZExtension’ signal to ‘on’.
External synchrocheck bypass signal ‘ExtSCBypas'
This I/P provides facility for bypassing the ‘synchroChck’ and
‘CO Ready’ (or SynchroChck2’ and ‘CO Ready 2’ for CB2) enabling I/P’s.
It is only active for the first fast three-phase or single-phase reclosure attempt.
External extension of the dead time ‘Extend t1'
A logical ‘1’ at the ‘Extend t1’ I/P extends the dead times ‘t Dead1
1P’ and ‘t Dead1 3P’ by the setting ‘t Dead1 Ext’ for the first
(fast) reclosure attempt. This could be necessary, for example, in
the event of a communication channel failure or in a redundant Close CB and signalling outputs
The most important auto-reclosure output is the ‘Close CB’
command which must be assigned to a heavy-duty auxiliary O/P
relay. This and 14 other heavy-duty and signalling O/P’s are provided.
