  • Decomposition Characteristics of SF6 and Partial Discharge

    Experimental results show that the negative DC partial discharges caused by the four defects decompose the SF6gas and generate five stable decomposed components, namely, CF4, CO2, SO2F2, SOF2, and SO2. The concentration, effective formation rate, and concentration ratio of SF6decomposed components can be associated with the PD types.

  • Drying and particle filters absorb moisture, gas and dust

    On the suspicion that SF 6 gas in a circuit breaker is contaminated or humid, we strongly recommend the use of drying and particle filters between switchgear and service cart. Moisture and both gaseous and dusty decomposition products as well as oil aerosols are adsorbed by special drying and particle filters during the recovery operation. Thus, service carts are protected effectively against contamination as most of the moisture and decomposition products are collected by the prefilter units.
