  • Fourier transform infrared spectroscopy quantitative

    Feb 05, 2015A critical PD quantity exists when electrical decomposition occurs in SF 6 gas. If the PD quantity is under the critical value, SF 6 decomposes minimally. By contrast, complicated decomposition occurs when the PD quantity is higher than the critical value. Fig. 6(a) shows the variation trend of the characteristic component SOF 2.Cited by: 21
