IEEE Guide for Dissolved Gas Analysis in Transformer Load Tap Changers

Methods of testing and evaluating dissolved gases in mineral based transformer oils found in Load Tap Changers (LTCs) are discussed and recommended in this guide. General types of LTC mechanisms, breathing configurations and electrical design are included as evaluation criteria for determining when mechanical damage or failure has occurred. Dissolved Gas of the LTC is required. This guide is not manufacturer specific, rather category specific.

IEEE Guide for Dissolved Gas Analysis in Transformer Load Tap Changers

General types of load tap changer (LTC) mechanisms, breathing configurations, and electrical designs, described for reference for determining methods of testing and evaluating dissolved gases in mineral-based transformer oils in LTCs, are discussed and recommended in this guide. Measurements of dissolved gas concentrations in the LTC oil are required to implement this guide. This guide is not manufacturer specific, rather category specific. ** Downloads file posted at http://standards.ieee.org/downloads/C57/C57.139-2015/
