SF6 Filling and Recovery

Gas insulated switchgear utilizes an insulating gas between each phase and ground to minimize the overall physical size of the installed equipment. The maintenance and inspection procedures share many of the same attributes as HV SF6 circuit breakers. The specific manufacture procedures should be adhered to for each GIS installation. PowerSafe can assist manufactures who do not have local support to perform gas handling, vacuum processing, pre-energization tests and commissioning, and support warranty and maintenance activities.

SF6 services include

  • Onsite SF6 testing (for purity, moisture content, and by-products).
  • Gas filling for new equipment
  • Gas recovery, vacuum and refilling of SF6 gas, for maintenance and decommissioning

Our teams are experienced with HV and MV equipment from all major manufacturers, including Alstom, Siemens, ABB, Meppi, Hico, and Mitsubishi
