1038 BAR
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.

1045 CB Discrepancy 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).
