Abstract
High Voltage (HV) insulation relying on the use of sulfur hexafluoride SF6 has passed the required qualification tests to become the most commonly used insulating gas in electrical systems to date1. Gas Insulated Switchgear (GIS) power substations have all of their components interconnected and insulated via compressed SF6, i.e. circuit breakers, dissconnectors, power switches, bushbars, current transformers, power transformers, cable insulation etc2, 3. Due to their compactness and steel shielding, they offer significant savings in land use, are aesthetically acceptable, have relatively low radio and audible noise emission levels, and enable substation installation in cities very close to the loads.
