Indications (IND)
Indications is a list of signals that were activated during the total recording time of the
disturbance (not time-tagged), see section
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, see section
"Event recorder"
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, see section
"Sequential of events"
Trip value recorder (TVR)
The recorded trip values include phasors of selected analog signals before the fault and
during the fault, see section
Disturbance recorder (DR)
Disturbance recorder records analog and binary signal data before, during and after the
fault, see section
"Disturbance recorder"
Fault locator (FL)
The fault location function calculates the distance to fault, see section
LMBRFLO"
for more detailed information.
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:
PreFaultrecT + tFault + PostFaultrecT or PreFaultrecT + TimeLimit , depending on
tRecording =
which criterion stops the current disturbance recording
