Dissolved gas analysis, measurements and interpretations
2018Oil-filled power transformers were first conceived and manufactured in the mid-tolate-1800s. They were (and to this day are) an essential component of the electrical power transmission and distribution infrastructure. Power transformers perform a power conversion function.

Highly sensitive Raman system for dissolved gas analysis in water
Applied Optics, 2016The detection of dissolved gases in seawater plays an important role in ocean observation and exploration. As a potential technique for oceanic applications, Raman spectroscopy has already proved its advantages in the simultaneous detection of multiple species during previous deep-sea explorations.

Transformer Fault Diagnosis by Dissolved-Gas Analysis
IEEE Transactions on Industry Applications, 1980The great majority of incipient faults occurring in power transformers gives evidence of their presence early in their developmental stages. Oil and oil-impregnated electrical insulating materials can decompose under the influence of thermal and electrical stresses generating gaseous decomposition products which dissolve in the mineral oil.

New techniques for dissolved gas-in-oil analysis
IEEE Electrical Insulation Magazine, 2003Dissolved gas analysis (DGA) is one of the major maintenance tools for monitoring faults in high-voltage electrical equipment in service. An increasing number of oil samples are analyzed for DGA in laboratories. This paper, a report of CIGRE Task Force 15-01-07, evaluates several newly developed techniques to extract gas from oils.
