Power Quality Analysis

PSM-A includes extensive power quality analysis features:

      • Trigger on voltages and/or currents.
      • Trigger on sags, swells, absolute transients, and relative transients
      • Capture data as logged events for scatterplots and table views of events
      • Capture events as a detailed waveform view of the event
      • Capture events as Half-cycle RMS summaries for recognition of overall profile of the sag/swell event
Voltage Dip Waveform with 7 labels

Waveform Captures

  1. Master scroll bar for quick navigation through each of the waveforms of the study session
  2. Recursive zooming
  3. Filter by event type
  4. Summary of event by magnitude and duration
  5. Numbered order of the event
  6. Trigger threshold
  7. Precise time of event
Voltage Dip Waveform with Labels

Advanced Analysis and Custom Presentation

  1. Set name and sub-title of presentation
  2. Custom on-graph labels
  3. Multitude of “Measurement Cursors”, for precise measurement and presentation
  4. Time or magnitude of each measurement cursor
  5. Elapsed time or magnitude between two measurement cursors
Inrush Event Logs with Labels

Half-Cycle RMS Graphs

  1. Summary of event by magnitude and duration
  2. Trigger threshold, as a number
  3. Numbered order of the event
  4. Trigger threshold, graphical
  5. Precise time of the event
Abs and Rel Transients with 7 labels

Scatter Plot View

  1. The Event Scroll Bar allows you to quickly cycle through event points for comparison and review.
  2. switch between graph of magnitude or graph of duration
  3. flexible triggered event type selection
  4.  Combine as many (or few) different signals as you wish. As many vertical axes as are needed will appear to support the selections.
  5. Display and highlight different phases.
  6. Sample Values.  Wherever your cursor lies on an event, the timestamp, magnitude, and trigger type of events is shown under the cursor
  7. Zooming.  Repetitive zooming is supported to allow viewing any detail of interest.
Transient Graph with Labels

Event Analysis

  1. Title and Sub-Title Control.  In addition to the global settings for title and sub-title, you can set them for specific displays prior to to printing or export to reports.
  2. You can quickly switch to viewing other data types from the same monitoring session
  3. On-Screen Labels.  If there is a point of special interest, insert a label pointing to the spot with the text of your choice.
  4. Summary Measurements. Values are displayed at the top in the Summary Header.
Event Logs with Labels

Event Log View

  1. Easy navigation among all the various associated data views and files
  2. Sort events by signal or trigger type
  3. Sort events by magnitude or duration
  4. All the same export methods as other displays enjoy
Percent to Standard Trigger Config

Percent to Standard Triggering

  1. The default thresholds for swell/sag and fast relative/absolute transients are automatically set as a % deviation from the standard for the attached voltage system. You can over-ride the defaults to suit your needs.
  2. Extensive collection of “standard” voltages from around the world that are automatically detected and used for triggering by % deviation.
Fixed Trigger Level Configuration

Fixed Trigger Level

  1. Set specific trigger magnitudes for voltage swell/sag and for high speed absolute and relative transient triggering
  2. Optional tool to get “suggested” transient trigger levels
  3. Set specific trigger magnitudes for current inrush/swell/sag and high speed transient triggering.
  4. Select or deselect the signals that you wish to trigger on.
Harmonics Graph with 6 Labels

Waveform Harmonics: Bar Chart

  1. Choose to view harmonics as a graph or as a table
  2. Select signals to show, in multiple ways
  3. Optional “context summary” measurements can be displayed on the graph, showing W, PF, and VA at the time of the waveform capture
  4. Summary measurements for each signal are at top: including THD as % or magnitude and showing specific harmonic measurements wherever the mouse cursor is located
  5. Values can be presented as % to the fundamental or as V and A RMS magnitudes.
  6. Values are shown in brackets for the specific harmonic where cursor is located
PSM-A Harmonics Text

Waveform Harmonics: Table

  1. Show each harmonic as percent or as RMS magnitude
  2. Choose to limit or expand the data shown
        • Toggle between all harmonics or only odd harmonics
        • Toggle phase angles on or off
        • Toggle between all magnitudes or only magnitudes of relevant size

Data Export

  1. Capture the display as a picture, in multiple picture formats (such as .jpg), excluding the ribbons and controls
  2. Export to Excel for custom analysis of the formatted raw data
  3. Share the data file via email
  4. Print in high definition color
  5. Control the colors and line thickness for print and/or display.
