PM180 Substation Automation Unit 23
The logical controller launches the Waveform recorder and Data recorder to record
the input waveforms and measured quantities at the time of the event. Control
setpoints can also be linked to the Event recorder and Sequence-of-Events recorder
to record setpoint transition events into the event log files.

Recording
Event Recorder
The Event recorder automatically records time-tagged self-supervision events related
to configuration changes, resets and device diagnostics. The logical controller can
also be programmed to trigger the Event recorder in order to put the events
monitored through programmable setpoints into the event report. See
Configuring the
Event Recorder in Chapter 8 for more information on programming the Event
recorder.
Sequence-of-Events Recorder
The Sequence-of-Events recorder automatically records time-tagged fault events and
programmable digital inputs, relay outputs and setpoint transition events. See
Configuring the Sequence-of-Events Recorder in Chapter 8 for more information on
programming the Sequence-of-Events recorder.
Power Quality Recorder
Depending on the order, the PM180 may be supplied with either the IEEE 1159
Power Quality recorder, or EN50160 Power Quality recorder.
The recorder continuously monitors voltage inputs and records time-tagged
disturbances and faults into the power quality event log. The EN 50160 Power
Quality recorder also provides the EN 50160 statistics counters for standard
compliance reports, and long-term harmonics survey statistics. All power quality
triggers have programmable thresholds and can be adjusted for specific applications.
The IEEE 1159 Power Quality recorder automatically classifies disturbance events by
IEEE 1159 disturbance categories. The IEEE 1159 Power Quality reports can also
combine traditional IEEE 1159 voltage disturbance categories with fault current
disturbances and protective relay fault information for complete “cause and effect”
fault and disturbance analysis.
The Power Quality recorder is programmed to trigger the Waveform recorder and
Data recorder to record input waveforms and long-duration RMS trends during the
time of the disturbance. See
Configuring the IEEE 1159 Power Quality Recorder and
Configuring the EN50160 Power Quality Recorder in Chapter 8 for more information.
Fault Recorder
The programmable Fault recorder records time-tagged fault events into the fault
event report. It can be triggered externally through any digital input or internally from
the embedded fault detector. The internal fault detector can automatically detect
different fault categories using the device’s own sub-cycle measurements. The fault
triggers have programmable thresholds and hysteresis that can by adjusted for
specific substation conditions.
The Fault recorder can be programmed to trigger the Waveform recorder and Data
recorder to record input waveforms and long-duration RMS trends during the time of
the fault. See
Configuring the Fault Recorder in Chapter 8 for more information.
Time Synchronization
Time synchronization can provide a common time basis for the fault recorders in a
protection or control system so that events and disturbances within the entire station
can be compared to one another.
The PM180 can receive time synchronization signal either from a GPS satellite clock
that has an IRIG-B time code output, or from another device that can provide minute-
