Guide for the Interpretation of Gases Generated in Silicone-Immersed Transformers
|Publication Date:||22 September 2005|
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:
- 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
- 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.
