  • Quantitative infrared spectroscopic analysis of SF6

    May 30, 2001The quantitative analysis of the decomposition products of SF 6, obtained under various electrical stress conditions, was investigated using FT-IR spectroscopy and PLS-calibration. This technique provides the sensitivity necessary to determine reliable concentrations in the low ppm v and for some components even in the sub-ppm v range using a transmission cell of 10 cm pathlength.

  • 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.
