  • PGE Phases Out SF6 in HV Substation GIS | TD

    10 mins readJan 27, 2020Dry-air/vacuum is the lowest-cost life-cycle option at present. Dry-air/vacuum has been tested up to 65-kA interrupting current and 230-kV rated voltage. From the three qualified GIS suppliers that used dry-air/vacuum, one could not meet PGE’s schedule, so the decision came down to the initial cost of the equipment.
