Monitoring
Indications (IND)
Indications is a list of signals that were activated during the total recording time of the
disturbance (not time-tagged).
Event recorder (ER)
The event recorder may contain a list of up to 150 time-tagged events, which have occurred during
the disturbance. The information is available via the local HMI or PCM600.
Sequential of events (SOE)
The sequetial of events may contain a list of totally 1000 time-tagged events. The list information
is continuously updated when selected binary signals change state. The oldest data is overwritten.
The logged signals may be presented via local HMI or PCM600.
Trip value recorder (TVR)
The recorded trip values include phasors of selected analog signals before the fault and during the
fault.
Disturbance recorder (DR)
Disturbance recorder records analog and binary signal data before, during and after the fault.
Time tagging
The IED has a built-in real-time calendar and clock. This function is used for all time tagging within
the disturbance report
Recording times
Disturbance report DRPRDRE records information about a disturbance during a settable time
frame. The recording times are valid for the whole disturbance report. Disturbance recorder (DR),
event recorder (ER) and indication function register disturbance data and events during
tRecording, the total recording time.
The total recording time, tRecording, of a recorded disturbance is:
tRecording =
1084
PreFaultrecT + tFault + PostFaultrecT or PreFaultrecT + TimeLimit , depending on
which criterion stops the current disturbance recording
