Power Disturbances

When your PQube 3 records an event, it places files on your SD card (and optionally emails them to you). Your PQube 3 generates summary files, GIF picture graphs, and .CSV spreadsheet files that provide much more information.

PQube 3 automatically generates GIF files which can be opened by any picture program. You don’t need any special software. You can also place GIF Graphs directly in Windows PowerPoint® presentations, Microsoft Word® reports, and so on.
Waveform Graph  |  CSV (ASCII) waveform data files (generated by PQube 3)
The waveform graphs show you the detailed shapes of the instantaneous voltage and current waveforms.
This is useful when you are looking for specific details, at the millisecond level. Your PQube 3 measures all of the waveforms at 512 samples per cycle, but to graph a longer duration, you can choose to record fewer samples per cycle if you prefer (the measurements will not be affected).
RMS Graph  |  CSV (ASCII) RMS data files (generated by PQube 3)
The RMS graphs show the cycle-by-cycle true RMS values of the voltage and current, updated every half cycle, and they also show the frequency. This is useful when you are looking at more general characteristics of the event, at roughly the one-second level, especially if you are interested in the available energy.
The CSV files contain every data point recorded for an event. It is a standard file format and so it can be opened with almost any spreadsheet program, including Excel®.
CSV Files
The CSV files are useful if you want more detailed data, and the ability to sort individual recordings and customize your own graphs.
The event summary files give you all the critical data on an event. Each file format contains the same information, it is just formatted differently for different applications.
.HTM files
Very user friendly and open automatically with any web browser (just double-click them)
.TXT files
Easy to read. Universal
.XML files
Easier for a computer to read than the other formats.
Consider using this file if you are building an automated monitoring system.

Power flows, load currents, harmonics, unbalance, energy... trended daily, weekly or monthly

Your PQube 3 records minimum/average/maximum for all parameters, cumulative probability statistics, and load duration statistics over the day, week or month. Those continuous recordings are trended in graphs generated by the PQube 3 itself!

Trends and statistics are very useful to assess power consumption, or correlate power disturbances with other parameters at the time of the disturbance. They are always available independently, even if there is no occurrence of events. Trends and statistics recordings give you information about what happened on the systems that your PQube 3 is monitoring, even if there weren’t any events.

Graphs provide all of the trend and statistics data every day, week, and month. Your PQube 3 records graphs for every channel, including voltage, current, power, THD, RMS Flicker, Carbon, and more. These recordings include readings every minute (for daily recordings) or every 5 minutes (for weekly and monthly recordings).
Power Trend and Statistics Graph  |  Graph (GIF) files (generated by PQube 3)
Your PQube 3 records trend and statistic data for all channels that it measures. This is an example of a power trend and statistics graph. These recordings include readings every minute (for daily recordings) or every 5 minutes (for weekly and monthly recordings). This graph contains the average reading every one or five minutes as well as the minimum and maximum updated five times a second.

CSV Spreadsheet files contain all of the same information that the GIF Graphs do. It is a standard file format and so it can be opened with almost any spreadsheet program, including Excel®.

Trend CSV Spreadsheet  |  CSV data files (generated by PQube 3)
The CSV Spreadsheet files are useful if you want more detailed data, and the ability to customize your own graphs.

Trend summary files give you all the critical data from your trend data. Each file format contains the same information, it is just formatted differently for different applications.

PQDIF  |  PQDIF data files (generated by PQube 3)

PQube 3 is standards-based: it supports PQDIF, 61000-4-30 Ed3, and has advanced standards-based communication abilities (email, FTP, web server, etc).

.HTM files

2kHz-150kHz Conducted Emissions

When your PQube 3 records an event, it places files on your SD card (and optionally emails them to you). Your PQube 3 generates summary files, GIF picture graphs, and .CSV spreadsheet files that provide much more information.

GIF picture files can be opened by any picture program. You don’t need any special software. You can also place GIF Graphs directly in Windows PowerPoint® presentations, Microsoft Word® reports, and so on.
GIF picture
The 2kHz-150kH range voltage conducted emissions, captured at a major laboratory building. The start and end hours of operation of the lab are clearly identifiable, and there is a typical frequency signature around 88kHz and 100kHz.

CSV Spreadsheet files contain all of the same information that the GIF Graphs do. It is a standard file format and so it can be opened with almost any spreadsheet program, including Excel®.

Trend CSV Spreadsheet
The CSV Spreadsheet files are useful if you want more detailed data, and the ability to customize your own graphs.

Other disturbances: earthquakes, DC supplies, and more

When your PQube 3 records an event, it places files on your SD card (and optionally emails them to you). Your PQube 3 generates summary files, GIF picture graphs, and .CSV spreadsheet files that provide much more information.

GIF picture files can be opened by any picture program. You don’t need any special software. You can also place GIF Graphs directly in Windows PowerPoint® presentations, Microsoft Word® reports, and so on.
Seismic Disturbance
A small earthquake, captured by a PQube 3 with an ENV2 EnviroSensor®‘s X-Y-Z accelerometer.
DC Monitoring
Disturbance on a 380 VDC supply, caused by a brief AC power interruption
High Frequency impulse recording  |  Download data files (generated by PQube 3)
A PQube 3 captures a high-frequency impulse, caused by switching a nearby inductive load. Recorded at one million samples-per-second simultaneously on four channels (four million samples-per-second on one channel is user-selectable, too).

Mechanical Shock
A tiny mechanical shock — in this case, an operator’s rolling chair bumping into a sensitive semiconductor tool — captured by a PQube 3 with an ENV2 EnviroSensor®‘s X-Y-Z accelerometer.
