Doble introduces the Delphi Mini to detect early signs of transformer deterioration
Doble Engineering Company has developed the Delphi Mini – a cost-effective dissolved gas analysis (DGA) monitor. The newest addition to the Doble Delphi product line came as a result of customer feedback based on meeting the needs of professional engineers in the field.
The US electric grid is under pressure lately due to rapidly aging transformers and the lack of investments. As a result, electric power professionals find it difficult to accurately test and track transformer performance.
Delphi Mini is designed as a “check engine light” for transformers as it continuously provides single value readings of either hydrogen or composite gas that indicate when intervention is necessary in real time and the requirement for further testing or more costly monitoring measures. The device helps in maintaining the reliability and life of transformers by giving professionals the ability to detect sudden changes in dissolved gas levels as they become evident and preventing possible, long-term, or catastrophic damages, that could cost up to several million dollars.
“The Delphi Mini puts us one step closer toward helping electric power professionals at every stage while they service and maintain power transformers,” said Dr. Tony McGrail, Solutions Director, asset management and monitoring technology at Doble Engineering Company.
“At Doble, we are committed to providing the best resources on the market, supported by the most advanced consulting professionals and testing services in the industry, to prevent failures where possible and give adequate warning of system deterioration,” he added.
Delphi Mini features include:
• continuous, on-line dissolved gas measurement – a key indicator of transformer health
• self-monitoring technology that ensures the data provided is valuable and actionable intelligence
• immunity to failure during oil surges, maintenance, and other activities as a result of its patented vacuum resistant membrane.
