Autorecloser Close command to CB: Initiates the reclose
command pulse to the circuit breaker. This output feeds
a signal to the Reclose time-delay, which maintains the
linked reclose contact closed for a time sufficient to
ensure reliable CB mechanism operation. This DDB
signal may also be useful during relay commissioning to
check the operation of the autoreclose cycle. Where
three single pole circuit breakers are used, the AR Close
contact will need to energise the closing circuits for all
three breaker poles (or alternatively assign three CB
Close contacts).
One-pole autoreclose cycle in progress: A single pole
autoreclose cycle is in progress. This output will remain
activated from the initial protection trip until the circuit
breaker is closed successfully or the autoreclose
function is Locked Out, indicating that a dead time
timeout is in progress. This signal may be useful during
relay commissioning to check the operation of the
autoreclose cycle.
Three-pole autoreclose cycle in progress: A three phase
autoreclose cycle is in progress. This output will remain
activated from the initial protection trip until the circuit
breaker is closed successfully or the AR function is
Locked Out, indicating that a dead time timeout is in
progress. This signal may be useful during relay
commissioning to check the operation of the autoreclose
cycle.
First high speed autoreclose cycle in progress: Used to
indicate the autorecloser is timing out its first dead time,
either a high-speed single-pole shot or a high speed
three-pole shot.
Further autoreclose cycles in progress: Used to indicate
the autorecloser is timing out delayed autoreclose dead
times for shots 2, 3 or 4. Where some protection
elements should not initiate autoreclosure for Delayed
Autoreclose (DAR) shots, the protection element
operation is combined with 'A/R 234 in Prog' as a logic
AND operation in the Programmable Scheme Logic, and
then set to assert the DDB:'BAR' input, forcing lockout.
Autorecloser signal to force all trips to be 3 Ph: This is
an internal logic signal used to condition any protection
trip command to the circuit breaker(s). Where single-
pole tripping is enabled, a fixed logic converts single-
phase trips for faults on autoreclosure to three-pole trips.
A/R Trip 3P can be connected to Main2 as an external
"Force 3-pole"
1 = ('Internal A/R' setting enabled) AND (No 'A/R SPAR
Enable')
0 = 'A/R SPAR Enable' AND ('Internal A/R' setting enabled)+
('Inhibit Window' at 0)
