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.

This guide is intended to apply to **silicone-immersed transformers** in which the silicone liquid was the liquid supplied when the transformer was originally manufactured.

This guide addresses the following:

  • The theory of combustible gas generation in a silicone-filled transformer
  • Recommended procedures for sampling and analysis
  • The interpretation of gas analysis
  • Recommended actions based on the interpretation of 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 for silicone-filled transformers.

Other techniques such as fixed instruments and gas space analysis may well have utility for silicone-filled units; however, due to a lack of data at this time, this guide will focus only on DGA.
