AbolishedGuide to the analysis and the diagnosis of gases dissolved in transformer oil
变压器油中溶解气体分析和判断导则
Application Summary AI generated
This standard provides a systematic methodology for analyzing gases dissolved in transformer insulating oil and interpreting the results to diagnose internal faults such as partial discharge, overheating, or arcing. It is applied by power utilities and electrical equipment manufacturers for condition monitoring of oil-filled transformers, reactors, and other high-voltage apparatus to prevent failures and guide maintenance decisions. The standard is specifically used in the context of periodic oil sampling and laboratory testing for power transmission and distribution systems.
