Description
Block distance element time delay
At 1: The distance timer will be blocked & DIST will
start but will not perform a Trip command.
Reset to 0: Opto input power off if signal assigned to
an opto input
OR DDB at 0 if signal assigned to a DDB cell
Authorization signal from external check Synchroniser
(via opto input, with a dedicated PSL) for reclosing with
internal autoreclose (indicates that Check Sync
conditions are met by an external device – The DDB
cell should be assigned afterwards an internal AR
logic),
If an opto input is assigned in the PSL, the autoreclose
close command will be verified by an external check
synchronism device. The input is energised when the
Check Sync conditions are met.
Phase A trip by external protection relay. This input
can be used to update the CB condition monitoring.
Opto input is assigned to External Trip A (external Trip
command issued by main 2 or to initiate the internal
A/R backup protection). External trip is integrated in
the DDB: 'Any Trip'. As for an internal trip, no dwell
timer is associated to it.
Phase B trip by external protection relay. This input
can be used to update the CB condition monitoring.
Opto input is assigned to External Trip B (external Trip
command issued by main 2 or to initiate the internal
A/R backup protection). External trip is integrated in
the DDB: 'Any Trip'. As for an internal trip, no dwell
timer is associated to it.
Phase C trip by external protection relay. This input
can be used to update the CB condition monitoring.
Opto input is assigned to External Trip C (external Trip
command issued by main 2 or to initiate the internal
A/R backup protection). External trip is integrated in
the DDB: 'Any Trip'. As for an internal trip, no dwell
timer is associated to it.
Frequency Inhibition
Frequency tracking does not work correctly (provides a
Frequency Out-of-Range indication)
Excessive Fault Frequency CB Trip pre lockout Alarm
(maximum number of fault): An alarm is issued at (n)
value in the counters of Main lock out or Fault
