SF6-alternatives Components Detection for testing

PDF Alternatives to SF6 in HV Circuit Breaker Insulation. A SF6 gas insulated circuit breaker uses the superior dielectric SF6 gas at a moderate pressure (typically 600 kPa) for phase to ground insulation and insulation across open contacts. The high voltage conductors and circuit breaker interrupter mechanisms are encapsulated

  • Western Power Distribution - SF6 Alternatives

    The project will improve on the current knowledge of SF6 alternatives. The test results will provide a clear indication on SF6 alternatives in 11kV RMUs. This will support the development of SF6 free switchgear. Reports generated through the project will be disseminated to other DNOs and other relevant stakeholders.
