Doble has created a variety of online devices to manage the state of your bushings/CTs, transformers, circuit breakers, and other apparatus.
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.
Accurate moisture and temperature data is necessary to determine the condition of electrical apparatus or its insulating liquid. However, the data by itself may not always be sufficient to identify potential problems, especially in transformer systems. Doble developed one of the first analytical techniques for measuring dissolved water in oil and the first online moisture monitor: DOMINO.
Intelligent Diagnostic Devices
Intelligent Diagnostic Devices (IDDs), a family of continuous online diagnostic devices for power system apparatus, are designed to detect incipient problems with bushings/CTs, transformers, and circuit breakers. Now you can safely manage progressive problems and efficiently schedule corrective action. There are three types of IDD instruments: Moisture, Bushings, and Dissolved Gas Analysis.
