SF6 End-of-life Measurement for high voltages

A service life of 50 years for GIS of the first and second generation is readily achievable for GIS with hitherto acceptable reliability, if a few measures for lifetime extension are introduced: Replacement of cast resin insulated voltage transformer, if any, by SF6 film insulated transformer.
