Annotation of standard text IEEE C57.146-2025 :

Revision Standard - Active.

This guide is intended to apply to silicone-immersed transformers for which the silicone liquid was the liquid supplied when the transformer was originally manufactured. It does not address transformers that have been retro-filled. The theory of combustible gas generation in a silicone-filled transformer, recommended procedures for sampling and analysis, recommended actions based on the interpretation of results, and a bibliography of related literature are addressed in this guide.
