This paper mentions the deficiency of present test methods for oil-dissolved gas content of the 330 kV and 500 kV oil-immersed transformer in service
and suggests that it would take a comprehensive view of judging the test results and understanding the limitation of no more than 3% of oil-dissolved gas content defined in the publication of "Preventive test code for electric power equipment".
