10. To select the channels, click on the “Channels” button, check the
boxes for channels to be recorded, and then click OK. Note that
the standard (20A) and extended (100A) current channels may not
be recorded together in the same file.
11. Save your waveform setup to the site database, and send it to the
device.
The picture above shows the factory preset waveform logs. Waveform log #7 is used
with the PQ and Fault recorders to store fault events, and PQ transient and short
duration events. Waveform log #8 is used with the PQ recorder to store waveforms
related to harmonics events.
Configuring the IEEE 1159 Power Quality Recorder
The Power Quality (PQ) recorder identifies the IEEE 1159 power quality events and
records them to the log file with the precise start and end timestamps and a fault
magnitude. The IEEE 1159 PQ report can be retrieved from the device, stored on a
PC and displayed on the screen as shown in Section “Viewing the IEEE 1159 Power
Quality Log”. Impulsive transients and short-duration voltage variations (sags and
swells) can also be viewed as magnitude/duration pairs on the well-known ITIC curve
chart for assessing the minimum equipment immunity.
The PQ recorder can trigger the waveform recorder to record the fault waveforms
before, during and after the PQ event for detailed event analysis. It may be useful for
troubleshooting problems throughout electrical networks, for example, to identify and
locate the source of a power quality event and to select an appropriate solution.
PQ Events Evaluation
The events are classified in accordance with the IEEE 1159 power quality categories.
The table below shows the categories recorded by the device, the metering data
