Abstract Infrared spectroscopy shows an enormous potential for the analysis of by-products generated from electrical discharges in sulfur-hexafluoride (SF6) insulated equipment. Since by-product composition can be related to the fault genesis (arc, partial discharge or corona), the analysis of contaminated SF6 provides a valuable diagnostic tool. The IR-spectrometric results from discharge experiments are presented, carried out with the application of SF6 pressures around 300 kPa and an alternating voltage up to 30 kV. Under the discharge conditions used, the main by-products found are the sulfuroxyfluorides SOF4 and SO2F2 with concentrations correlated to the discharge time. Due to its toxicity, special attention is also paid to S2F10. The experimental conditions and practical aspects for reliable quantitative analysis of reactive species are discussed.
