Revision Standard - Active - Draft.
General types of on-load tap-changer (OLTC) mechanisms, breathing configurations, and electrical designs, described for reference for determining methods of testing and evaluating dissolved gases in mineral-based transformer oils in OLTCs, are discussed and recommended in this guide. Measurements of dissolved gas concentrations in the OLTC oil are required to implement this guide. This guide is not manufacturer specific, rather category specific.
