How can compressed-air leakage and electrical partial-discharge measurements recorded with the SONASCREEN 2 be evaluated and documented?

Two separate report applications are available for application-specific evaluation and documentation of SONASCREEN 2 measurements:

• LeakReport for compressed-air leaks
• PDReport for electrical partial discharges

The measurement is first performed using the corresponding measurement mode on the SONASCREEN 2 and is then saved in a format suitable for the respective report software.

LeakReport – documenting compressed-air leaks

In Compressed Air Leakage mode, the SONASCREEN 2 locates the leak and can already display the calculated:

• volumetric flow rate, and
• resulting leakage costs

during the measurement.

The measurement can then be saved for further processing in LeakReport.

LeakReport provides functions including:

• creation and editing of leakage reports,
• description of the leak location,
• documentation of the estimated loss,
• recording of repair status,
• individual processing of individual leaks,
• export of the report as a PDF.

A report can therefore provide an overview of the compressed-air leaks detected within a system and serve as a basis for necessary repair activities.

Potential energy and cost savings associated with the detected leaks can also be documented.

PDReport – analysis and documentation of partial discharges

In Partial Discharge mode, the SONASCREEN 2 locates the acoustic source and displays a live PRPD diagram during the measurement.

The measurement can then be saved in a format suitable for PDReport.

PDReport supports further analysis and assessment of the measurement and provides functions including:

• display of the acoustic signal as a PRPD diagram,
• automatic line-frequency detection,
• automatic differentiation between corona and surface partial discharge,
• documentation of detected anomalies or defects,
• creation of reports,
• export as a PDF.

The documented results can, for example, serve as a basis for further technical assessment and planning of necessary maintenance activities.

What is the difference between LeakReport and PDReport?

As a simplified guide:

• compressed-air leak measured: LeakReport
• electrical partial discharge measured: PDReport

LeakReport focuses on leakage loss, costs, and repair status, while PDReport is designed for the analysis and assessment of electrical partial discharges based on the acoustic signal and PRPD pattern.

Both applications therefore complement the application-specific SONASCREEN 2 measurement modes by providing structured evaluation and documentation.
