Advanced DGA Diagnostics


Advanced perspective on how dissolved gas analysis (DGA) results are interpreted – an important tool in the overall transformer maintenance program. Includes hands-on break out groups.

This class is intended to identify fault gases and what causes their formation; explain and provide examples of qualitative and quantitative interpretation of dissolved gasses. This class will also evaluate the condition of cellulose insulation and other non-routine tests, examine the role DGA plays in new oil testing and discuss procedures to obtain a representative sample from transformers, and how to mitigate risk.

Attendees are encouraged to bring their own transformer data to use as a case study for interpretation of dissolved gases or to help develop a maintenance program.
