DELPHI
Dissolved Gas Analysis Instruments
®

The Doble Delphi is a dissolved gas analysis (DGA) monitor that helps you
track transformer health by providing early warning signs of problems such as
overheating, insulation degradation or mechanical movement within the unit. The
Delphi provides this valuable information in real time, second by second. The Delphi
is immune to oil surges and vacuums that may affect other sensors; in addition,
the Delphi contains self-testing diagnostics to monitor its own performance. Use
the Delphi as part of your comprehensive fleet management program or to monitor
smaller transformers in a cost-effective manner.

• Cost-effective updates on transformer health between
regular DGA samples
• Alerts you when there is a sudden change in DGA levels due
to a developing fault within the transformer
• Notifications give you time to plan instead of reacting to a failure
• Actionable intelligence helps you determine what steps to
take: maintenance, testing, load management or replacement
