Superseded Standard

IEEE C57.139-2010

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.

PC57.139

Guide for the Interpretation of Gases generated in Liquid-Type Load Tap Changers

This guide describes methods of evaluating dissolved gases in insulating liquids used with load tap changers (LTCs). General types of LTC mechanisms, breathing configurations, and electrical design are included for evaluation criteria in determining when mechanical damage, deterioration or failure might have occurred.

C57.139-2015

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/

These standards have been replaced with a revised version of the standard, or by a compilation of the original active standard and all its existing amendments, corrigenda, and errata.


No Superseded Standards

These standards have been removed from active status through a ballot where the standard is made inactive as a consensus decision of a balloting group.


No Inactive-Withdrawn Standards

These standards are removed from active status through an administrative process for standards that have not undergone a revision process within 10 years.


No Inactive-Reserved Standards
