PQube File Formats
Your PQube provides data in several useful formats.
• Events, trends, and statistics as universal GIF formats and .CSV
data files
• Text, XML and HTML summaries
• PQDIF files (IEEE standard for power quality data files)
Each graph and chart is labeled in two languages (28 languages total).
All PQube graphs are generated by your PQube directly, without software, and can be viewed in a browser or opened in any picture viewer.
They are included in event notification emails as simple GIF file attachments, and can be forwarded to a third party, such as a facility engineer
or utility company.
PQube Sample Files
You can see more graphs like these at map.PQube.com—free
PQube data streamed live from around the globe.
The PQube web interface access screen. From here, you can check
your PQube status, access the meters, view events, and give
commands to your PQube. Each PQube can be labeled with a unique
name and location, making it easy to moinitor multiple PQubes.

PQube-generated waveform and RMS
graphs of a voltage sag recorded at a
machine shop. The graphs give you the
time, depth, and duration of the event, and
a snapshot of your power at the beginning
and end of the event.
With PQube-generated graphs like this
you can:
• Prove to your utility that a sag
happened
• Rule out power problems during
troubleshooting—by showing that no
events occurred
• Identify the source of your power
problems
• Understand how your equipment
affects the power in your facility.

Weekly harmonics distortion
graph for voltage and current.
Voltage harmonics can pollute
the grid and affect other loads.
Current harmonics increase
losses in transformers and wiring.
High current harmonics will
distort the voltage, which can
affect your loads.

PQube-generated temperature and humidity graph. Your PQube
has two temperature-humidity ports, alowing you to monitor
the temperature and humidity at two locations, up to 10 meters
away from the meter (with optional PSL extension cables). This
is important in applications that are sensitive to environmental
conditions, such as photovoltaic plants and data centers.
Customize your PQube data. All
PQube data is available in .CSV
format. You can open these files
in any spreadsheet program such
as Microsoft Excel® and use it to
create your own custom graphs and
reports.
