Abstract

Electrical utilities use sulfur hexafluoride (SF₆) as an electrical insulator in many components of their power systems. Under normal conditions SF₆ is stable, but in electrical discharges SF₆ decomposes into many byproducts. With an FT-IR spectrometer and a 20-m cell, we have examined the byproducts from various discharges and obtained quantitative analyses of components down to 1 ppm (part per million) or less. We discuss the advantages and disadvantages of FT-IR spectroscopy relative to other techniques for diagnosing the insulating gas condition inside electrical power equipment.
