PQDIF Explorer is a simple desktop application designed for low-level visualization of data stored in the Power Quality Data Interchange Format.

The following lists some of the features of the PQDIF Explorer.

  • Low-level visualization to complement other higher-level tools, such as PQDiffractor.
  • Allows unambiguous discovery of all information in PQDIF files -- including information hidden by higher-level tools, such as invalid tags.
  • Useful for validation of the output produced by systems that need to write PQDIF files.
  • Includes an XML file which describes all the tags and IDs in the PQDIF standard.
  • Custom tags or IDs can be added to the XML and will be reflected in the PQDIF Explorer.
  • Includes the GSF.PQDIF library which contains GPA's PQDIF parser for .NET applications.
  • Ability to gracefully handle malformed files.
  • Ability to see exceptions encountered while parsing files.
