SF6 decomposition QUALITY for KEPCO

SF6 decomposition QUALITY for KEPCO

Sulphur Dioxide is the most common decomposition by-product measured during sf6-gas gas quality analysis. Unlike most other decomposition products, it is relatively unreactive once formed, so its concentration remains stable over time, so measurement results are more.
