Section 6
IED operation
6.2.1

DFR recording triggering

DFR recordings are normally triggered by IED applications when they detect fault events. DFR
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.
6.2.2

DFR record analysis

The IED collects disturbance records of fault events which are set to trigger the DFR recorder. DFR
data is collected and stored for later viewing and analysis. The DFR recorder data can be read and
analyzed, for example, with PCM600.
6.2.3

DFR reports

PCM600 can be used for creating reports of DFR recorder data.
6.2.4

IED self-supervision

The IED self-supervision handles internal run-time fault situations. The main indication of an
internal fault is a flashing green Normal 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.
The IED records IED status data and events.
6.3

IED parameterization

IED parameters are set via the LHMI or PCM600.

Only authorized and skilled personnel should analyze the errors and decide on
further actions.
Document all the recorded data from the IED before resetting the tripping and IED
lockout functions.
