Doble Engineering Company products

The Doble Delphi is a compact on-line DGA sensor that mounts directly to a transformer valve or can be mounted adjacent to the transformer when the need arises. The Delphi is a robust instrument housed in a stainless steel enclosure that uses proven fuel cell technology to provide a reliable indication of the gas levels in the oil with easy to understand displays. It is made specifically for the substation environment both in durability and immunity to interference from substation noise.
