We will briefly see how it became the most popular test, whether it is justified, the principle of the gas formation mechanism from a chemist’s point of view, and finally the significant changes that appear in the new version of IEEE and new CIGRE brochure. The changes will also influence the revision of IEC60599.

In this lecture, students will understand the new principle of the correct DGA diagnosis from an insight view of a chemist, users, and analyst on this field.

The presentation will clarify:
1. How and why DGA gained its popularity in our days. It has only occurred in the last two decades.
2. A concise summary of how DGA has technologically advanced throughout the last century.
3. What are the main principles of the previous approach for DGA diagnosis
4. What are the main developments for the new DGA diagnosis
5. A summary of existing devices for achieving DGA results, online, portable, and laboratory.
6. A brief review of the advantages and disadvantages.
