4. Select the waveform logging options for PQ
events.
5. Download your setup to the device.
The picture above shows the default PQ recorder settings. The available options are
listed in the following table.
Option Range Default Description
PQ Log
Threshold, % 0-200.0% Defines the operating threshold for the PQ trigger in
percent of the nominal (reference) value
Hysteresis, % 0-50.0% Defines the hysteresis for the PQ trigger in percent of
the threshold
Enabled Checked
Unchecked
Enables recording PQ events for specific voltage
characteristics
Waveform Log
On Start Checked
Unchecked
Checked Enables waveform log when the PQ event starts
On End Checked
Unchecked
Unchecked Enables waveform log when the PQ event ends
Log No. 7-8 Specifies the waveform log file used for waveform
recording on the PQ event
The waveform log options allow recording waveforms both at the start and the end of
a PQ event. Since the voltage variations can last from some seconds to minutes, this
allows capturing and analyzing the voltage transitions using short time waveform
recording at the start and at the end of the voltage sag or swell.
You can temporary disable the PQ recorder in your device. To enable or disable the
PQ recorder:
1. Check or uncheck the “Recorder Enabled”
checkbox.
2. Send your setting to the device.
Note that disabling the PQ recorder in your device does not affect the evaluation and
recording of the EN50160 statistics.
Power Quality Event Indication and Cross Triggering
When the PQ recorder detects a power quality fault, it generates the specific internal
event PQ EVENT that can be monitored through a control setpoint to give a fault
indication via relay contacts. The event can be found under the STATIC EVENTS
group in the setpoint trigger list.
