Waveform Visualization Tool.


LiveWire is a simple data analysis program for scientists and engineers who want to visualize and analyze large amounts of waveform data. It supports the importation and exportation of industry standard data file formats, such as COMTRADE[1], EMTDC[2], and PTI (PSS/E). It also provides users with the ability to import and export general data formats such as comma separated variable files (*.csv) and text files (*.txt). LiveWire even provides the means to generate data from user-defined equations and import/export data from other applications using the clipboard.

LiveWire has a very wide range of built in features like smart axis and dynamic aperture controls in both the graphs and plots allow the user to easily navigate through their data. Enhanced tool tips present the user with thumbnail views of data sets. The ability to save and restore LiveWire workspaces (*.lww) provide support for worksheets and imported data files with recreating them each time. The capability to generate Bitmap and Metafile images on a frame-by-frame basis, allowing users to add results and visual depiction to their reports quickly.


  • Power quality
  • View  and study of logged process data
  • Performance automotive
  • Electro-magnetic/mechanical transients
  • Control systems
  • Signal analysis
  • Economic projections
  • Stock analysis
  • Geological fault analysis
  • Metallurgy (strain and stress analysis)
  • Astronomy (background noise radiation analysis)

What kind of data can be imported?

LiveWire can import/export files that are compliant with the following industry standards:

  • COMTRADE[1] - (IEEE industry standard for transient data exchange, power quality studies)
  • EMTDC[2] - (PSCAD file format)
  • PTI (PSS/E) - (Power Technologies Inc. PSS/E 25)
  • Comma Separated Variable - (General format)
  • Text and Tab Delimited - (General format)

Data can also be copied from any application complying with Microsoft Windows standards and pasted directly into LiveWire.

Simple to use.

LiveWire fills that need with a simple robust design. The workspace is a split window containing a "navigation tree" on the right and a "worksheet" on the left.


Z Systems has a 3-step approach to data analysis.

  • Step 1
    Import your data - Data will appear as a tree item on the navigation tree.
  • Step 2
    Create your graph - Choose from any of the many graphs and place it anywhere on the worksheet.
  • Step 3
    Insert your data into the graph - Copy the data from the navigation tree and paste into the graph.
