What are the standards for dissolved gas analysis of transformer oil?

The standards for dissolved gas analysis of transformer oil typically reference methods including IEC 60567 and ASTM D3612, which outline the procedures for sampling and analyzing the gases dissolved in transformer oils, such as hydrogen, methane, ethane, and others. These standards specify the appropriate equipment, sampling techniques, and analytical methods to provide accurate and reliable results. Compliance with these standards is essential for assessing the condition of transformer oil and diagnosing potential issues in transformers, ensuring the reliable operation of electrical equipment. Regular dissolved gas analysis helps detect insulation breakdown, overheating, and other electrical faults, making it a critical practice in transformer maintenance.
