The performance of dissolved gas analysis (DGA) in network transformers is a growing industry trend, and a technique which may aid utilities in managing network transformer fleets. This technology has been applied in large power transformers for many years, but utilities have limited experience with it on distribution transformers. This research presents current practices and understanding of the use of DGA in network transformers through case studies of application and describes laboratory-based assessments of online DGA monitors.
