SF₆ Monitoring, Recycling and Regeneration: Circular Solutions for the Energy Sector

Sulfur hexafluoride (SF₆) has long been the reference insulating medium for high-voltage and extra-high-voltage installations due to its remarkable dielectric strength, chemical stability, and capability to ensure compact, reliable, and safe equipment. Gas-insulated switchgear, circuit breakers, and other HV components rely extensively on SF₆ to guarantee service continuity under demanding operating conditions. However, its extremely high global warming potential makes the environmental impact of SF₆ emissions a critical issue for the electrical power sector.
