  • Decomposition Characteristics of SF6 and Partial Discharge

    The decomposition characteristics of SF6 under four types of negative DC partial discharge (DC-PD) are obtained. The relationship between the decomposition characteristics of SF6 and the PD types was further studied. Moreover, back propagation (BP) neural network algorithm [29–38] is used to recognize the PD types.

    Sep 01, 2000 · Abstract Insulating gas mixtures containing SF 6 have been promoted to serve as replacements for pure SF 6 in order to reduce SF 6 atmospheric emission. It has been argued that some synergism may be achieved by choosing proper buffer gases in mixtures with SF 6 such that the buffer gases efficiently slow down electrons into an energy range where the electron attachment cross section for SF 6
