Tony McGrail, Solution Manager for On-line Diagnostics at Doble Engineering Company said that the dissolved gas analysis was a critical component of power transformer asset management and condition-based maintenance programs. They had been working with their clients to give them a DGA product that meets their needs, at the quality level expected from Doble.
The Doble Delphi provides both dissolved gas monitoring and moisture measurements and will set new standards in on-line monitoring he said. It is the latest addition to the company’s on line condition monitoring tools. It delivers critical information in real time and provides substation engineers with intelligent alerts and trend analysis to aid in the management of high value assets.
The Delphi is a tough and rugged device which has been designed to with stand the harsh environmental conditions of a substation as it tracks the by-products of deterioration. It is available as a hydrogen monitor or composite gas monitor and can be mounted directly to a transformer valve.
It uses proven fuel cell technology and optional micro-pump circulation for accurate measurements with easy to read alarms that appear on the Delphi display and computer software. The Doble Delphi comes with the option to measure moisture in oil.
