This guide is intended for the application of dissolved gas analysis (DGA) techniques on oil-immersed transformers and reactors applied during factory temperature rise tests. It contains recommended procedures for sampling, recommended actions based on interpretation of results, and a bibliography of related literature.

This document provides guidance in the application of dissolved gas analysis (DGA) to transformers and reactors subjected to factory temperature rise tests. This document consists of evaluation procedures and guidelines for acceptable levels of gases generated in conventional mineral oil-fi lled transformers and reactors during factory temperature rise tests.
