Waveforms on your meter’s webpages
You can use the waveform viewer on the meter’s webpages to view waveforms
generated as a result of power quality events.
Overview of how to setup and view waveforms on your meter’s webpages
Before you can view waveforms on the meter’s webpages, you need to perform
some basic configuration to enable waveform capture and store the waveforms in
COMTRADE format.
1. Enable waveform capture on
your meter
Set the meter’s nominal voltage using ION
Setup or the webpages.
2. A waveform is captured when
a power quality event occurs
A COMTRADE record is generated and
saved to your meter’s ftp site.
3. View the waveform on the
meter’s webpages
Go to the waveform viewer (Monitoring >
Waveforms) to explore the waveform data.
The waveform viewer uses the meter’s COMTRADE files to display the
waveforms. If the events you want to capture are not included in the default
framework, you can customize the meter’s waveform recording framework.
