To enable or disable the Fault recorder in your
meter:
1. Check or uncheck the "Recorder Enabled" checkbox.
2. Send the new setting to the device.
Voltage and current thresholds are normally specified as a
percent of a nominal (reference) voltage and current. The
voltage reference is the line-to-neutral PT secondary
voltage for the 4LN3 and 3LN3 wiring configurations, and
the line-to-line PT secondary voltage for other wiring
configurations. The reference value for current triggers is
the CT secondary current rating. See
in Chapter 5 for information on specifying voltage and
current ratings in your device.
To make easier specifying thresholds for voltage and
current triggers, PAS shows you threshold values in
secondary units that match the percentage you selected
for the triggers. To update the secondary thresholds, type
the threshold for a trigger in percent, and then press Enter
or click elsewhere on the Fault recorder setup tab.
Default
Thresholds
Defines the operating threshold for the fault
trigger in percent of the nominal (reference)
value
Shows the setup value in secondary units for
the selected operating threshold
5.0 Defines the hysteresis for fault trigger in
percent of the threshold
Checked Links the fault trigger to the Fault Recorder. If
the box is leaved unchecked, the Fault Recorder
does not respond to the trigger.
Waveform Log
Checked Enables waveform log when the fault event
starts
Unchecked Enables waveform log when the fault event
ends
7 Specifies the waveform log file used for
waveform recording on the fault event
1/2-cycle RMS Plot
Unchecked Enables concurrent RMS trace plot to the data
log file while the fault event continues
100 Maximum duration of the 1/2-cycle data trend
log. The logging is stopped automatically when
either a fault event ends or the specified
number of cycles has been recorded.
4 The number of cycles to be recorded prior to
the event
4 The number of cycles to be recorded after the
event
13 Specifies the data log file used for data
recording on the fault event
