Errors can be caused by external or internal events damaging the IED. Internal
supervision functionality monitors different types of internal errors. These can be
divided to hardware errors, runtime errors in application or operating system and
communication errors. Further actions always depend on the cause of the errors.
Only authorized and skilled personnel should analyze the errors and
decide on further actions.
Internal IED errors may be caused by:
•
Hardware errors
•
Runtime errors
•
Communication errors
The IED records:
•
IED self-supervision report
•
Event list
•
System registrations
Document all the recorded data from the IED before you reset the
tripping and IED lockout functions.
5.2.4
Disturbance recording triggering
Disturbance recordings are normally triggered by IED applications when they detect
fault events. Disturbance recordings can also be triggered manually or periodically.
5.2.5
Disturbance record analysis
The IED collects disturbance records of fault events which are set to trigger the
disturbance recorder. Disturbance data is collected and stored for later viewing and
analysis. The disturbance recorder data can be uploaded and analyzed, for example,
with PCM600.
For more information, see PCM600 documentation.
5.2.6
Disturbance reports
PCM600 can be used for creating reports of disturbance recorder data.
