Convert PQA to another file type

To convert your PQA file to another format, you need PQSCADA Sapphire or other Data software.

Convert a file to PQA

To convert other file formats to the "Electrical Grid Analysis" file type, you need software like PQSCADA Sapphire or a similar tool.

About PQA files

A .pqa file is most commonly a Power Quality Analysis data archive generated by Elspec electrical network recorders. These files act as high-resolution containers for continuous waveform recordings, capturing critical grid parameters like voltage sags, swells, harmonics, and frequency deviations.

The Problem: The .pqa format is proprietary and heavily compressed to store gigabytes of time-series data efficiently. You cannot open it with Microsoft Excel, Notepad, or standard database tools. Users often find themselves locked out of their own data without the specific, enterprise-grade PQSCADA Sapphire software.

The Solution: To analyze this data in MATLAB, Python, or Excel, you must convert the file.

For Analysis: Convert to CSV or XLSX. This flattens the complex time-series data into rows and columns, making it readable by standard data science tools.
For Interoperability: Convert to PQDIF (Power Quality Data Interchange Format) or COMTRADE. These are the IEEE standard formats for sharing disturbance data between different software vendors.
For Reporting: Export to PDF for non-technical stakeholders.

Secondary Use Case: In rare legacy contexts, a .pqa file may be a Palm Query Application. These are obsolete "web clippings" (mini-websites) from the early 2000s used on Palm OS PDAs. They are essentially PDB databases containing HTML 3.2 assets.

Convert.Guru analyzes your PQA file, detects the exact format, and lets you read the text inside.

FAQ

If you want to convert PQA file to DB, SQLITE, SQLITE3, MDB, ACCDB, DBF, ODB, FDB, GDB, MYD, FRM or SQL, you can use PQSCADA Sapphire or similar software from the "Power Quality Analysis Data" category. In the File menu, look for Save As… or Export….

The PQA Converter Story

The history of Convert.Guru began over 25 years ago in California with Tom Simondi’s file-format database. A former contributor to Space Shuttle development and a software pioneer of the 1980s, Simondi established a trusted resource for file type analysis that was even referenced by Microsoft Windows XP. Today, we use modern technology to process and convert thousands of file formats while continually improving our PQA converter.
