description | In this paper, the amount of SF<sub>6</sub> decomposition gases due to the partial discharge (PD) was studied in the SF<sub>6</sub> gas-insulated transformer. The long-term PD degradation experiment was performed while controlling the discharge magnitude using the surface discharge, and the gas generation amount was measured by using gas chromatography for SO<sub>2</sub>F<sub>2</sub>, SOF<sub>2</sub>, SO<sub>2</sub>, CO, and CF<sub>4</sub>. In addition, to investigate the relationship between the partial discharge energy and the decomposed gas generation amount, partial discharge energy was calculated by a data processing program and converted to the unit of joule per mole. With the finite element method (FEM), the electric field distribution and SF<sub>6</sub> gas decomposition mechanism were explained for the partial discharge energy effect on the gas generation. This study helps understand the relationship between the partial discharge energy and the decomposed gas generation ratio with the experimental results and can be used for the diagnosis of PD and maintenance process for the gas-insulated transformers. |
