  • Optical Partial Discharge Diagnosis in SF 6 Gas-Insulated

    May 15, 2018Abstract: This paper aims to promote optical partial discharge (PD) detection from laboratory scale to practical application for sulfur hexafluoride (SF 6)-insulated power equipment.First, a micro silicon photomultiplier (SiPM)-based PD sensor is evaluated for detecting PDs in SF 6 gas and is proven to have the equivalent properties with pulse current acquisition and vacuum photomultiplier

  • Formation Characteristics of SF 6 Decomposition under

    As partial discharge applied voltage increases, the production rates of CO 2 and CF 4 increase, but the ratio of CO 2 to CF 4 decreases. Based on the experiments, the formation mechanisms of SF 6 decomposition by-products under varying degrees of severity of partial discharge are analyzed.

  • Characterization of SF6 / Argon Plasmas for

    Two mixtures of Ar/SF6, 10/90 and 50/50, and pure C4F8 discharges were investigated. The 10/90 Ar/SF6 mixture was investigated using actinometry (F atom line at 703.75 nm intensity ratio vs. Ar atom line at 750.39 nm). We could not sustain a pure SF6 discharge with the oxide wafer in place. The center of the matrix of power and

  • Evaluating DC Partial Discharge With SF 6 Decomposition

    Abstract: This study mainly aims to obtain the decomposition characteristics of SF6 under various degrees of negative partial discharge (PD) and establish a method for evaluating the internal PD fault for gas-insulated equipment (GIE). Thus, metal protrusion, a frequent insulation defect in DC GIE, was used in the study of PD characteristics from the initial discharge to the near breakdown

  • Mechanism of Trace O 2 on SF 6 Characteristic Decomposed

    Jan 17, 2020Trace O 2 significantly affects the diagnosis accuracy of decomposed components analysis method for spark discharge due to its direct participation in SF 6 decomposition process. Therefore, spark discharge decomposition experiments were conducted under different proportions of SF 6 /O 2 mixtures. The influence rules and mechanisms of φ(O 2) on the content and characteristic ratio of SF 6

  • Fourier transform infrared spectroscopy quantitative

    Feb 05, 2015However, when partial discharge (PD), a spark, an arc, or overheating occurs in SF 6 gas, some SF 6 molecules decompose and produce SF 4, SF 3, SF 2, S 2 F 10, and some other low-fluoride sulfides. These low-fluoride sulfides have very active chemical properties and react with impurities, such as H 2 O and O 2 in SF 6 gas.
