  • Breakdown Gradients in SF6-N2, SF6-Air and SF6-CO2 Mixtures

    Abstract: A method to calculate the uniform field breakdown gradients for SF6-N2, SF6-air and SF6-CO2 mixtures is discussed. Calculated values of the breakdown gradients in these mixtures are compared with experimentally measured values using plane-plane electrode configuration and direct applied voltages. The results show a reasonably good degree of agreement between the calculated and the measured values.

  • Thermal Decomposition Properties of Epoxy Resin in SF6/N2 Mixture

    Abstract. As a promising alternative for pure SF 6, the mixture of SF 6 /N 2 appears to be more economic and environment-friendly on the premise of maintaining similar dielectric properties with pure SF 6. But less attention has been paid to the thermal properties of an SF 6 /N 2 mixture, especially with insulation materials overheating happening simultaneously.

  • Characteristics of Partial Discharges on a Dielectric Surface

    Due to the strong electronegative character of SF 6 and its tendency to decompose during a discharge, the PD patterns in SF 6-N 2 mixtures are notably different from those in air. The measured PD pulse rate and average current show that partial discharges in SF 6 -N 2 mixtures in the presence of an epoxy surface are non-stationary, that is they
