Description
Block internal autoreclose: Block Autoreclose (via an
opto input or in the PSL).
The DDB:'BAR' input will block the autoreclosure and
lockout the autoreclose if a cycle is in progress. If a
single-pole cycle is in progress a three-pole trip will be
issued and the autorecloser will lock out. It can be
used when protection operation is required without
autoreclose. A typical example is for a transformer
feeder, where autoreclosing may be initiated by the
feeder's protection relay but blocked by the
transformer's protection relay. Similarly, where a circuit
breaker low gas pressure or loss of vacuum alarm
occurs during the dead time, autoreclosure should be
blocked – and BAR can be used to perform this
blocking logic.

CB Phase A status (from internal logic and CBAux opto
inputs state: 1 = CB-Pole A is open.
This signal is used for Any Pole Dead & All Pole Dead
internal detection.
Circuit breaker pole A closed
(status input from CB, 52-A = normally open)
Circuit breaker pole A open
(Status input from CB, 52-B = normally closed)
CB Phase B status (from internal logic and CBAux opto
inputs state: 1 = CB-Pole B is open.
This signal is used for Any Pole Dead & All Pole Dead
internal detection.
Circuit breaker pole B closed
(status input from CB, 52-A = normally open)
Circuit breaker pole B open
(Status input from CB, 52-B = normally closed)
CB Phase C status (from internal logic and CBAux
opto inputs state: 1 = CB-Pole C is open.
This signal is used for Any Pole Dead & All Pole Dead
internal detection.
Circuit breaker pole C closed
(status input from CB, 52-A = normally open)
Circuit breaker pole C open
(Status input from CB, 52-B = normally closed)
CB Discrepancy (one pole open).
If it is assigned to an opto input in the PSL and
energised, the DDB:'CB Discrepancy' signal will inform
the protection of a pole discrepancy status (one pole
opened and the other two poles closed). It must be set
to high logical level before Dead time 1 has elapsed –
it can also be generated internally (see Cbaux logic).
