Dissolved Gas Analysis in Transformer Oil Using Transformer Oil Gas Analyzer and TurboMatrix HS Sampler



Transformers aid in the delivery of electricity, and issues with transformers can result in an interruption of power supply to consumers. To prevent such interruptions, transformers must be properly maintained and monitored. An effective means of conducting routine monitoring towards this goal of reduced outages includes the analysis of oil insulting the transformers for a variety of dissolved gases.

ASTM offers reference test methods, such as ASTM D3612 Method C which utilizes a headspace sampler to extract dissolved gases for GC analysis. In this application note, an analysis following this method is outlined, utilizing a PerkinElmer turnkey Transformer Oil Gas Analyzer (TOGA) system with a TurboMatrix Headspace Sampler.
