DELPHI PORTABLEPortable Dissolved Gas Analyzer

DOBLE IN-SERVICE TESTING & ASSESSMENT

FEATURES

Measures key gases and moisture

Combines traditional DGA analysis and Dobles own Dissolved Gas Anomaly Indication system: DG-AI

Easy to operate user interface within the device

Printer built in to the test set for a hard copy of your results

Dissolved gas analysis (DGA) is a powerful diagnostic tool to help you understand the health and condition of power transformers and other oil-filled equipment. The Delphi Portable, part of Dobles line of DGA instruments, provides timely and actionable information on key dissolved gases in insulating oil. This portable device helps identify and track faults by monitoring composite gas levels and tracking individual gases when those levels change.

The Delphi Portable uses patented technology for accuracy and repeatability, giving you the data you need to make effective asset maintenance and operational decisions. The standard Delphi provides a highly cost-effective check engine light monitoring approach; the Delphi Portable is used when you need a closer look at the data.
