The Doble Delphi Instruments are dissolved gas analysis monitors that help you track transformer health by providing early warning signs of problems such as overheating, insulation degradation or mechanical movement within the unit. The Doble Delphi provides this valuable information in real time, second by second. 

The Doble Delphi is immune to oil surges and vacuums that may affect other sensors; in addition, it contains self-testing diagnostics to monitor its own performance. 

The Doble Delphi is available in Standard and Mini models. Each mounts directly to a transformer valve or can be mounted adjacent to the transformer when the need arises. Use the Delphi Mini as part of your comprehensive fleet management program or to monitor smaller transformers in a cost-effective manner.
