  • Static Field Breakdown of SF6-N2 Mixtures in Rod-Plane Gaps

    Mixtures containing 0 to 100% SF6 are studied over a pressure range of 100 to 500 kPa. The results show that for such gaps, the dielectric behavior of SF6-N2 mixtures is very similar to that of pure SF6. A discontinuity is reported in the breakdown voltagepressure characteristics of SF6 and SF6-N2 mixtureswhen the rod electrode is positive.

  • Problems of the application of N2/SF6 mixtures to gas

    Sep 21, 2001 · In designing a gas‐insulated bus (GIB) using N 2 /SF 6 mixtures, there are many application problems, such as the mixture pressure needed in order to maintain the required dielectric and heat transfer performance. Problems of recycling SF 6 are also essential in applying N 2 /SF 6 mixtures.
