The reversal of SF6/N2 gas mixtures polarity effect under lightning impulse

In recent years, SF<sub>6</sub>/N<sub>2</sub> gas mixture gains much popularity as an alternative insulating medium of pure SF<sub>6</sub> gas among gas-insulated equipment because of the greenhouse effect and poor economy effectiveness of the latter. This paper investigated the breakdown characteristics of SF<sub>6</sub>/N<sub>2</sub> gas mixture with low… CONTINUE READING
