Tóm tắt

The components of desorbed gases from alumina at surface flashover were analyzed by using a monochromator. As a result, we found spectra of hydrogen, oxygen and the material of electrodes (stainless steel Fe, Ni, Cr) and component of alumina (Al) at surface flashover. The intensity of spectra of hydrogen decreased with the accumulation of the number of surface flashover.
