IEEE C57.146-2005 PDF
This guide is intended to apply to silicone-immersed transformers in which the silicone fluid was the fluid supplied when the transformer was originally manufactured. This guide also addresses the following: a) The theory of combustible gas generation in a silicone-immersed transformer; b) Recommended procedures for sampling and analysis; c) The interpretation of Gas Analysis; d) Recommended actions based on the interpretation of the results and e) A bibliography of related literature.
The purpose of this project is to write a guide 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 Dissolved Gas Analysis.
