  • A Partial Discharge Detection Method for SF 6 Insulated

    Abstract: A partial discharge (PD) detection method for SF 6 insulated inverted current transformers (SIICTs) adopting an inner shield case as an ultra-high frequency (UHF) sensor is proposed in this paper. The inner shield case is a component of the SIICT. Its structure is similar to that of an antenna and can be used as a UHF sensorCited by: 6

  • High-precision density sensor for concentration

    2013-11-1The dielectric strength of SF 6 mixtures, i.e., its insulation capability, depends on the density and the mixing ratio which can change as a result of various fault scenarios. For the mixtures SF 6 /N 2 and SF 6 /CF 4, the dielectric strength does not vary linearly with SF 6 content. Both mixtures give rise to synergism, i.e., an over-proportional influence of SF 6Cited by: 11
