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 protection relay 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 signals.
5.2.2
Disturbance record analysis
The protection relay 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 read and analyzed with
PCM600.
For more information, see the PCM600 documentation.
5.2.3
Disturbance reports
PCM600 can be used for creating reports of disturbance recorder data.
For more information, see the PCM600 documentation.
5.2.4
Relay self-supervision
The relay self-supervision handles internal run-time fault situations.The main
indication of an internal fault is a flashing green Ready LED.
More detailed information can be found from
Main menu/Monitoring/IED status
or
Main menu/Monitoring/Internal events
.
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.
Only authorized and skilled personnel should analyze the errors and
decide on further actions.
