Document the disturbance before clearing the information from the
IED.
Only authorized and skilled personnel should analyze possible errors
and decide on further actions. Otherwise, stored disturbance data can
be lost.
5.2.1
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.
The manual trigger generates an instant disturbance report. Use this function to get a
snapshot of the monitored line.
5.2.2
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 with
PCM600.
For more information, see PCM600 documentation.
5.2.3
Disturbance reports
PCM600 can be used for creating reports of disturbance recorder data.
For more information, see PCM600 documentation.
5.2.4
Internal IED errors
The IED self-supervision handles internal run-time fault situations. The main
indication of an internal fault is a flashing green Ready LED.
Internal faults can be divided to hardware errors, run-time errors in the application
or operating system and communication errors. Further actions always depend on the
cause of the error.
