This signal picks up when the closing command is issued and
resets at the end of the time ‘t Close’ or earlier if there is a tripping occurs upon reclosing.
Status of the auto-reclosure function (‘AR Ready’ and ‘AR
Blocked’)
The signal ‘AR Ready’ is generated when the auto-reclosure
function is ready to perform a reclosure cycle and the signal ‘AR
Blocked’ when it is blocked.
The ‘AR Ready’ signal is active providing a reclosure cycle is not
blocked (no ‘AR Blocked’ signal) and a dead time is not running.
The ‘AR Ready’ signal is active during a reclose command for
purposes of enabling the synchrocheck function (see Fig. 3 in
the synchrocheck function section).Auto-reclosure cycle in progress
There are six signals which show that a reclosure cycle is running and what stage has been reached:
'AR in prog.' reclosure cycle in progress
'First AR 1P' first single-phase reclosure attempt
'First AR 3P' first three-phase reclosure attempt
‘second AR' second reclosure attempt
'Third AR' third reclosure attempt
'Fourth AR' fourth reclosure attempt.
The signal ‘AR in prog’ picks up at the start of the dead time and
is reset by the falling edge of the last reclose command.
Circuit-breaker closing signals ‘Close CB’ and ‘Close CB2'
The CB closing command is normally assigned to a heavy-duty
auxiliary O/P relay by correspondingly configuring the parameter
‘Close CB’ (also ‘Close CB2’ in a duplex scheme). It is also possible to assign the same signal to a signalling O/P under the
same parameter name.
A trip subsequent to a close command during the time ‘t Close’ +
300 ms switches the dead time step (second, third and fourth
AR) or initiates a lock-out trip (depending on the setting). A close
command is reset immediately after a trip.
Definitive trip ‘Def. Trip'
The ‘Def. Trip’ signal indicates that the circuit-breaker will remain
tripped and no further reclosure attempts will be made. The following conditions can cause a definitive trip:
All reclosure attempts were unsuccessful
