Description
Current transformers supervision indication: Indicates a
CT Fail detected after time delay has elapsed is issued
Circuit breaker failure on any trip
Broken current maintenance alarm (1st level): An alarm
maintenance is issued when the maximum broken
current (1st level) calculated by the CB monitoring
function is reached (see setting: 'CB monitor setup / I^
Maintenance')
Broken current lockout alarm (2nd level): An alarm Lock
Out is issued when the maximum broken current (2nd
level) calculated by the monitoring function is reached
Circuit breaker operations number alarm (1
alarm is issued when the maximum of CB operations is
reached. This alarm is initiated by internal (any
protection function) or external trip (via opto input). The
Alarm can be set with 'CB Monitor Setup / N° CB Ops
Maint.' setting.
Set to 0: Until number of operations is below the 'N° CB
0ps Maint.' setting. The DDB:'Reset all values' resets
this counter.
Circuit breaker operation number lockout (2
alarm): An alarm is issued when the maximum of CB
operations is reached [initiated by internal or external
trip, see setting: 'CB Monitor Setup\N° CB Ops Lockt.]
Set to 0: Until number of operations is below the 'N° CB
Ops Lockt." setting. The DDB:'Reset all values' resets
this counter.
CB excessive operating time alarm: An alarm is issued
when the operating tripping time on any phase pass over
the 'CB monitor setup / CB Time Maint' setting (slowest
pole detection calculated by I< from CB Fail logic)
CB locked out, due to excessive operating time: An
alarm is issued when the operating tripping time on any
phase pass over the 'CB monitor setup / CB Time
Lockout' setting (slowest pole detection calculated by I<
from CB Fail logic)
Excessive Fault Frequency CB Trip lockout Alarm
(maximum number of fault): An alarm is issued at (n-1)
value in the counters of Main lock out or Fault frequency
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 frequency
Lockout alarm: An alarm is issued with: 'Man CB
Unhealthy'or no 'Check Sync OK' (CB conditioning) or
'Man CB Cls Fail' or 'Man CB Fail Trip' or 'F.F. Lock' or
'CB Op Time Lock' or 'CB Ops Lockout'
Circuit Breaker Alarm
Displayed when a CB Failure or CB State unknown
condition is detected (the 'System data / Plant Status'
two last digits = 00 or 11). The CB discrepancy status is
detected after CBA time-delay issued by opto input or
internally by CBAux logic – Alarm issued after 5 s
Alarm CB Fail for manual trip command
Alarm CB fail for manual closing command
Alarm CB performed by unhealthy condition
Autoreclosed works without check synchronism (high
when the internal Check Synchronism conditions are not
met).
