| Abstract: | Aimed at three 500 kV single-phase transformer's insulating oil all appear the excess hydrogen content before operation,based on characteristics of insulating oil gas produced in the mechanism and test data,the estimate and analysis are carried out.It is shown that the excess hydrogen content caused by the release of hydrogen adsorbed on the transformer components surface. |
