The guide's application is for natural and synthetic ester-immersed transformers. This guide addresses the following: The theory of combustible gas generation in a natural and synthetic ester-filled transformer; Interpretation of the dissolved gas analysis results; Recommended actions based on the interpretation of dissolved gas analysis results; A bibliography of related literature. The purpose of this guide is to assist the transformer operator in evaluating dissolved gas analysis (DGA) data obtained from natural ester and synthetic ester-filled transformers. New IEEE Standard - Active. Natural and synthetic ester-immersed transformers are handled in this guide.
