Only authorized and skilled personnel should analyze possible
errors and decide on further actions. Otherwise, stored disturbance
data can be lost.

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.

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.

Disturbance reports

PCM600 can be used for creating reports of disturbance recorder data.
For more information, see the PCM600 documentation.

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.
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.
The protection relay records system registrations, relay status data and events.
